課題を解決するための手段及び発明の効果Means for Solving Problems and Effects of Invention

上記課題を解決するために、本発明のブラケットの取付構造は、
電子制御部品のケースに組付け可能なブラケットのパネル部材への取付構造であって、
前記ブラケットは、前記ケースとの組み付け状態において前記ケースの主面に対面する主面対向部と、前記主面対向部における第一側で、前記組み付け状態の前記ケースから離れる向きに延出する挿通係止部と、前記主面対向部における前記第一側とは逆の第二側で、前記組み付け状態の前記ケースから離間する向きに延出し、その先で前記第二側へと向きを変えて延出する弾性変形可能なアーム状の回り込み係止部と、を備え、
前記パネル部材は、前記挿通係止部に対応して設けられた第一取付孔と、前記回り込み係止部に対応して設けられた第二取付孔と、を備え、
前記挿通係止部が、前記第一取付孔に対し挿通係止された挿通係止状態となり、かつ前記回り込み係止部が、前記第二取付孔に対し挿通され、前記パネル部材の背面側に回り込んで前記第二側へと延出し、その先端部が前記パネル部材を背面側から押し付ける回り込み係止状態となることにより、前記ブラケットが前記パネル部材に取り付けられることを前提とする。 In order to solve the above problems, the bracket mounting structure of the present invention is
It is a mounting structure for the panel member of the bracket that can be assembled to the case of the electronic control component.
The bracket is inserted so as to extend away from the case in the assembled state at the main surface facing portion facing the main surface of the case and the first side of the main surface facing portion in the assembled state with the case. The locking portion and the second side of the main surface facing portion opposite to the first side extend in a direction away from the case in the assembled state, and then change the direction to the second side. Equipped with an elastically deformable arm-shaped wraparound locking part that extends
The panel member includes a first mounting hole provided corresponding to the insertion locking portion and a second mounting hole provided corresponding to the wraparound locking portion.
The insertion locking portion is inserted and locked with respect to the first mounting hole, and the wraparound locking portion is inserted through the second mounting hole and placed on the back surface side of the panel member. It is premised that the bracket is attached to the panel member by wrapping around and extending to the second side, and the tip portion thereof is in a wraparound locking state in which the panel member is pressed from the back surface side.

上記構成によれば、パネル部材の第一取付孔に、ブラケットの挿通係止部が挿通して係止し、パネル部材の第二取付孔に、ブラケットの回り込み係止部が挿通してパネル部材の裏側に回り込む形で係止することにより、ブラケットがパネル部材に取り付けられる。このとき回り込み係止部の先端部は、パネル部材を裏側から弾性的に押し付け続けるため、パネル部材とブラケットとの間に生じるガタつきを常に吸収することができる。 According to the above configuration, the insertion locking portion of the bracket is inserted into the first mounting hole of the panel member to lock it, and the wraparound locking portion of the bracket is inserted into the second mounting hole of the panel member to insert the panel member. The bracket is attached to the panel member by locking it around the back side of the. At this time, since the tip of the wraparound locking portion continues to elastically press the panel member from the back side, it is possible to always absorb the rattling that occurs between the panel member and the bracket.

本発明における前記主面対向部は、前記挿通係止部と前記回り込み係止部との間の、当該回り込み係止部側の位置に、前記パネル部材に正面側から当接する支点部を有して構成できる。この構成によれば、パネル部材にブラケットを組み付ける際に、てこの原理を利用することが可能になる。即ち、まずはブラケットの回り込み係止部をパネル部材の第二取付孔に挿通して当該パネル部材の裏面側に回り込ませ、その先端部を当該裏面に当接させる。この状態で、ブラケットの挿通係止部をパネル部材の第一取付孔に挿通して係止させる場合、挿通係止部を第一取付孔に押し込む途中で、ブラケットの支点部がパネル部材の正面に当接する。これにより、挿通係止部の第一取付孔への押し込みには、パネル部材に対する回り込み係止部の当接位置を作用点、パネル部材に対する支点部の当接位置を支点、挿通係止部を力点とした、てこの原理を利用できる。このとき、支点部は、回り込み係止部側に偏った位置に設けられているため、力点である挿通係止部を第一取付孔に押し込む力が小さくて済むから、組み付けやすい。 The main surface facing portion in the present invention has a fulcrum portion that abuts on the panel member from the front side at a position on the wraparound locking portion side between the insertion locking portion and the wraparound locking portion. Can be configured. According to this configuration, it is possible to utilize the principle of leverage when assembling the bracket to the panel member. That is, first, the wraparound locking portion of the bracket is inserted into the second mounting hole of the panel member to wrap around to the back surface side of the panel member, and the tip end portion thereof is brought into contact with the back surface side. In this state, when the insertion locking portion of the bracket is inserted into the first mounting hole of the panel member to be locked, the fulcrum portion of the bracket is in front of the panel member while the insertion locking portion is being pushed into the first mounting hole. Contact. As a result, when pushing the insertion locking portion into the first mounting hole, the contact position of the wraparound locking portion with respect to the panel member is the point of action, the contact position of the fulcrum portion with respect to the panel member is the fulcrum, and the insertion locking portion is used. You can use the principle of leverage as a fulcrum. At this time, since the fulcrum portion is provided at a position biased toward the wraparound locking portion side, the force for pushing the insertion locking portion, which is a force point, into the first mounting hole is small, so that it is easy to assemble.

本発明における前記挿通係止部は、前記第一取付孔への挿通係止状態において弾性変形して前記第一取付孔の前記第一側の内縁を前記第一側に押し付けて、前記ブラケットの全体を前記第二側へと押し付ける弾性係止片を有する一方、当該第二側への押し付けによって、前記回り込み係止状態の前記回り込み係止部の基端部が前記第二取付孔の前記第二側の内縁に押し付けるよう構成できる。これにより、パネル部材に取り付けられたブラケットは、上記第一側と上記第二側とにおいて押し付けあった状態となるため、上記第一側や上記第二側へのガタつきを抑制できる。 The insertion locking portion in the present invention is elastically deformed in the insertion locking state to the first mounting hole and presses the inner edge of the first side of the first mounting hole against the first side of the bracket. While having an elastic locking piece that pushes the whole to the second side, by pressing against the second side, the base end portion of the wraparound locking portion in the wraparound locking state is the first of the second mounting holes. It can be configured to be pressed against the inner edges on the two sides. As a result, the bracket attached to the panel member is in a state of being pressed against each other on the first side and the second side, so that rattling on the first side and the second side can be suppressed.

本発明における前記挿通係止部及び前記第一取付孔の内縁には、前記第一側に向けて押し付けてくる前記弾性係止片を前記第一取付孔の前記第一側の内縁に接触させた状態で、前記第一取付孔内の第一所定位置に止める第一の位置保持部を設けることができる。具体的にいえば、上記構成における前記挿通係止部は、前記主面対向部から延出し、その先端側から基端側に向かって前記弾性係止片が延出形成される支柱部と、前記支柱部に設けられ、前記第一取付孔への挿通係止状態において前記弾性係止片の押し付け方向に対し直交する直交方向の両側へと当該第一取付孔の内縁を押し付ける第一取付孔内縁押付部と、を有しており、前記第一の位置保持部は、前記第一取付孔内縁押付部と、前記第一取付孔における前記直交方向の両側の内縁と、により構成することができる。これにより、挿通係止部は、第一取付孔内において、上記第一側から上記第二側に向かう方向に対し直交する方向において押し付けあった状態となるため、当該直交方向へのガタつきを抑制できる。 With respect to the insertion locking portion and the inner edge of the first mounting hole in the present invention, the elastic locking piece pressed toward the first side is brought into contact with the inner edge of the first side of the first mounting hole. In this state, a first position holding portion that stops at the first predetermined position in the first mounting hole can be provided. Specifically, the insertion locking portion in the above configuration includes a strut portion extending from the main surface facing portion and the elastic locking piece extending from the tip end side to the proximal end side. A first mounting hole provided in the support column and pressing the inner edge of the first mounting hole to both sides in a direction orthogonal to the pressing direction of the elastic locking piece in a state of being inserted and locked into the first mounting hole. It has an inner edge pressing portion, and the first position holding portion may be composed of the first mounting hole inner edge pressing portion and the inner edges on both sides of the first mounting hole in the orthogonal direction. it can. As a result, the insertion locking portion is in a state of being pressed against each other in the direction orthogonal to the direction from the first side to the second side in the first mounting hole, so that rattling in the orthogonal direction is caused. Can be suppressed.

本発明における前記第一取付孔内縁押付部は、前記支柱部の前記直交方向の一方の端部から前記第一側へと延び出し、前記直交方向の内側へと弾性変形可能な弾性片を有し、前記第一取付孔は、前記挿通係止状態において当該弾性片に押し付けられる内縁が前記第一側に向かうほど前記直交方向の内側に位置する湾曲形状を有し、押し付けるその弾性片の延出先端側を当該湾曲形状に沿うよう弾性変形させるように構成できる。この構成によると、第一取付孔の湾曲形状をなす内縁に沿うよう弾性変形した弾性片によって、ブラケットは、前記直交方向の外側と前記第一側との双方に押し付けることができる。これにより、当該直交方向と、両係止部（挿通係止部及び回りこみ係止部）の対向方向との双方におけるブラケットのガタつきを抑制できる。 The inner edge pressing portion of the first mounting hole in the present invention has an elastic piece that extends from one end of the support column portion in the orthogonal direction toward the first side and elastically deforms inward in the orthogonal direction. The first mounting hole has a curved shape in which the inner edge pressed against the elastic piece in the insertion-locked state is located inward in the orthogonal direction toward the first side, and the elastic piece to be pressed is extended. It can be configured to elastically deform the protruding tip side so as to follow the curved shape. According to this configuration, the bracket can be pressed against both the outside in the orthogonal direction and the first side by the elastic piece elastically deformed along the curved inner edge of the first mounting hole. As a result, rattling of the bracket can be suppressed in both the orthogonal direction and the opposite direction of both locking portions (insertion locking portion and wraparound locking portion).

本発明において、前記第一取付孔の前記第一側の内縁は、円弧状に形成され、前記弾性係止片は、前記挿通係止部の挿通係止状態において円弧状の当該内縁に対し、前記第一側への押し付け方向に直交する直交方向における一方側とその逆の他方側との２位置で押し付ける形状をなし、前記回り込み係止部は、前記基端部が前記第二取付孔の内縁に対し前記直交方向の両側で接触する形状を有するとともに、それら両側の接触位置が、前記弾性係止片が前記第一取付孔の内縁を押し付ける前記２位置に対し、前記直交方向において外側に位置するように構成できる。この構成によると、第一取付孔の円弧状内縁を、弾性係止片が２点で押し付けることになる。そして、パネル部材に取り付けられたブラケットに、それら２点の対向方向への振動が生じた場合、それら２点は、第一取付孔の円弧状内縁上を摺動する形でガタつくが、それら２点のうちの一方が、当該円弧状内縁に食い込むよう押し付ける方向にも力を作用させるため、当該円弧状内縁上を摺動する方向への力が抑えられ、ガタつきを抑制することができる。 In the present invention, the inner edge of the first mounting hole on the first side is formed in an arc shape, and the elastic locking piece is formed with respect to the arc-shaped inner edge in the insertion locking state of the insertion locking portion. It has a shape of pressing at two positions, one side in the orthogonal direction orthogonal to the pressing direction to the first side and the other side opposite to the pressing direction, and the wraparound locking portion has a base end portion of the second mounting hole. It has a shape that makes contact with the inner edge on both sides in the orthogonal direction, and the contact positions on both sides are outward in the orthogonal direction with respect to the two positions where the elastic locking piece presses the inner edge of the first mounting hole. Can be configured to be located. According to this configuration, the elastic locking piece presses the arcuate inner edge of the first mounting hole at two points. Then, when the bracket attached to the panel member vibrates in the opposite direction of the two points, the two points rattle in the form of sliding on the arcuate inner edge of the first mounting hole. Since one of the two points also exerts a force in the direction of pressing against the arc-shaped inner edge, the force in the direction of sliding on the arc-shaped inner edge can be suppressed, and rattling can be suppressed. ..

上記構成における前記回り込み係止部及び前記第二取付孔の内縁には、前記弾性係止片によって前記第二側に向けて押し付けてくる前記基端部を、前記第二取付孔の前記第二側の内縁に接触させた状態で、前記第二取付孔内の第二所定位置に止める第二の位置保持部を設けることができる。具体的にいえば、上記構成における前記回り込み係止部は、前記基端部に設けられ、前記回り込み係止状態において前記挿通係止部が前記挿通係止状態となった場合に、前記第二取付孔の内縁を、当該基端部による前記第二側への押し付け方向に対し直交する直交方向の両側へと押し付ける第二取付孔内縁押付部を有しており、前記第二の位置保持部は、前記第二取付孔内縁押付部と、前記第二取付孔における前記直交方向の両側の内縁と、により構成できる。これにより、回り込み係止部は、第二取付孔内において、上記第一側から上記第二側に向かう方向に対し直交する方向において押し付けあった状態となるため、当該直交方向へのガタつきを抑制できる。 The base end portion that is pressed toward the second side by the elastic locking piece is pressed against the wraparound locking portion and the inner edge of the second mounting hole in the above configuration. A second position holding portion that stops at a second predetermined position in the second mounting hole can be provided in a state of being in contact with the inner edge on the side. Specifically, the wraparound locking portion in the above configuration is provided at the base end portion, and when the insertion locking portion is in the insertion locking state in the wraparound locking state, the second It has a second mounting hole inner edge pressing portion that presses the inner edge of the mounting hole to both sides in a direction orthogonal to the pressing direction of the base end portion to the second side, and has the second position holding portion. Can be configured by the second mounting hole inner edge pressing portion and the inner edges of the second mounting hole on both sides in the orthogonal direction. As a result, the wraparound locking portion is in a state of being pressed against each other in the second mounting hole in a direction orthogonal to the direction from the first side to the second side, so that rattling in the orthogonal direction is caused. Can be suppressed.

上記構成における前記挿通係止部において前記第一取付孔を前記第一側に押し付ける第一側押付領域と、前記回り込み係止部において前記第二取付孔を前記第二側に押し付ける第二側押付領域とにおいて、それぞれの押し付け方向に対し直交する直交方向の両端間の長さが異なるよう構成できる。これにより、ブラケットは、第一側押付領域と第二側押付領域とのうち領域幅の狭い側で１点、領域幅の広い側の両端で２点、合わせて３点でそれぞれ押し付け合う形で、パネル部材に対し組み付けられる。このような３点での支持は、それらのうち領域幅の狭い側と領域幅の広い側との対向方向へのガタつきを防止するだけでなく、それら３点を通過する平面上でそれら３点のうち１点を中心に回転する方向へのガタつきも抑えることができる。また、このような３点支持は、三脚等のように、２点や１点での支持に比べて安定し、かつ４点以上での支持より効率的である。 In the insertion locking portion of the above configuration, the first side pressing region for pressing the first mounting hole to the first side and the second side pressing for pressing the second mounting hole to the second side in the wraparound locking portion. It can be configured so that the length between both ends in the orthogonal direction orthogonal to each pressing direction is different from that of the region. As a result, the brackets are pressed against each other at one point on the narrow area side of the first side pressing area and the second side pressing area, and two points on both ends on the wide area side, for a total of three points. , Assembled to the panel member. Such support at three points not only prevents rattling in the opposite direction between the narrow area side and the wide area side of them, but also prevents them from rattling in the opposite direction on the plane passing through these three points. It is also possible to suppress rattling in the direction of rotation around one of the points. Further, such a three-point support is more stable than a two-point or one-point support, and is more efficient than a four-point or higher support, such as a tripod.

上記構成において、前記挿通係止部によって前記第一取付孔を前記第一側に押し付ける押し付け位置と、前記回り込み係止部によって前記第二取付孔を前記第二側に押し付ける押し付け位置とが合わせて３か所に設けられ、それら３つの係止部において、１つの係止部から他の２つの係止部までの押し付け位置間の距離がそれぞれ異なるようにすることができる。３つの係止部でパネル部材に対し組み付けられる場合、１つの係止部から他の２つの係止部までの距離が一致していると、パネル部材と平行な平面上において、１つの係止部から等距離にある２つの係止部が、その１つの係止部を中心に揺動する形で、ブラケットがガタつく可能性がある。しかしながら、１つの係止部から他の２つの係止部までの距離がそれぞれ異なっていることで、その１つの係止部を中心に揺動する２つの係止部の揺動軌跡が、径が異なる円弧状の軌跡となって一致しないため、それら２つの係止部が互いの揺動を阻止し、ガタつきを抑制することができる。 In the above configuration, the pressing position where the first mounting hole is pressed against the first side by the insertion locking portion and the pressing position where the second mounting hole is pressed against the second side by the wraparound locking portion are aligned. It is provided at three places, and in those three locking portions, the distances between the pressing positions from one locking portion to the other two locking portions can be made different from each other. When assembled to a panel member with three locking parts, if the distances from one locking part to the other two locking parts are the same, one locking on a plane parallel to the panel member. The bracket may rattle in the form of two locking portions equidistant from the portion swinging around the one locking portion. However, since the distances from one locking portion to the other two locking portions are different, the swing locus of the two locking portions swinging around the one locking portion has a diameter. Are different arcuate loci and do not match, so that the two locking portions can prevent each other from swinging and rattling can be suppressed.

上記構成における前記主面対向部は、前記第一側の端部から前記挿通係止部の前記弾性係止片の直下までを切り欠いた切り欠き部を有し、前記ブラケットが前記パネル部材に取り付けられた状態において、前記切り欠き部の前記第一側の開放側から棒状治具を進入させることにより、前記第一取付孔を通って前記ブラケット側に突出する前記弾性係止片の先端部を前記支柱部側に弾性変形させることを可能にできる。これにより、当該弾性変形によって前記挿通係止部の前記第一取付孔への挿通係止状態が解除されるから、ブラケットをパネル部材から容易に取り外すことが可能になる。 The main surface facing portion in the above configuration has a notch portion notched from the end portion on the first side to just below the elastic locking piece of the insertion locking portion, and the bracket is attached to the panel member. In the mounted state, the tip of the elastic locking piece that protrudes toward the bracket through the first mounting hole by allowing the rod-shaped jig to enter from the open side of the first side of the notch. Can be elastically deformed toward the support column side. As a result, the elastic deformation releases the insertion / locking state of the insertion / locking portion into the first mounting hole, so that the bracket can be easily removed from the panel member.

本発明の実施の形態につき図面に示す実施例を参照して説明する。 Embodiments of the present invention will be described with reference to the examples shown in the drawings.

本実施例では、図１及び図２に示すように、ブラケット１をケース１０１に組み付けるための組み付け構造１０００（図２参照）が形成されるとともに、図３及び図４に示すように、このブラケット１をパネル部材２００へ取り付けるための取付構造２０００（図４参照）が形成される。以下、これらの組み付け構造１０００及び取付構造２０００に関して説明する。 In this embodiment, as shown in FIGS. 1 and 2, an assembly structure 1000 (see FIG. 2) for assembling the bracket 1 to the case 101 is formed, and as shown in FIGS. 3 and 4, the bracket is formed. A mounting structure 2000 (see FIG. 4) for mounting 1 to the panel member 200 is formed. Hereinafter, these assembling structure 1000 and mounting structure 2000 will be described.

ケース１０１は、ＥＣＵ１００（Electronic Control Unit：電子制御部品）の筐体である。このため、本実施例の組み付け構造１０００は、ブラケット１をＥＣＵ１００に組み付けるための組み付け構造ともいえる。ＥＣＵ１００は、図１８及び図１９に示すように、ケース１０１と、ケース１０１に内包される回路基板１２０と、回路基板１２０と接続するコネクタ１３０と、を有する。 The case 101 is a housing of an ECU 100 (Electronic Control Unit). Therefore, the assembly structure 1000 of this embodiment can be said to be an assembly structure for assembling the bracket 1 to the ECU 100. As shown in FIGS. 18 and 19, the ECU 100 includes a case 101, a circuit board 120 included in the case 101, and a connector 130 connected to the circuit board 120.

ケース１０１は、互いに対向する四角形状の主面１０１ｂと、それら主面１０１ｂの対向空間の外周を取り囲む外周側面１０１ａと、を有する。ただし、ケース１０１の本体部１１１は、それら主面１０１ｂの対向空間の外周のうち三方（即ち３面）を被うのみであり、それら３方にそれぞれ長方形状の外周側面１０１ａを有する一方で、残りの一方（即ち１面）には開口部１１１Ｈが形成されている。回路基板１２０は、この開口部１１１Ｈから本体部１１１の内部に収容される。回路基板１２０には、端子部１３１を接続させる形でコネクタ１３０が組み付けられている。回路基板１２０が本体部１１１に収容された際、コネクタ１３０は、相手コネクタと接続する接続部１３２を開口部１１１Ｈから露出した状態とされる。ケース１０１は、この開口部１１１Ｈを覆うように本体部１１１に組み付けられるカバー１１２を有する。カバー１１２は、コネクタ１３０を露出させるコネクタ用開口部１１２Ｈを有し、コネクタ１３０とケース１０１の開口部１１１Ｈの内縁との間の隙間を塞ぐ形で、本体部１１１に対し組み付けられる。 The case 101 has a rectangular main surface 101b facing each other and an outer peripheral side surface 101a surrounding the outer periphery of the facing space of the main surfaces 101b. However, the main body 111 of the case 101 only covers three sides (that is, three sides) of the outer circumferences of the facing spaces of the main surfaces 101b, and each of the three sides has a rectangular outer peripheral side surface 101a, while the rest. An opening 111H is formed on one side (that is, one surface). The circuit board 120 is housed inside the main body 111 through the opening 111H. A connector 130 is assembled to the circuit board 120 so as to connect the terminal portion 131. When the circuit board 120 is housed in the main body 111, the connector 130 is in a state where the connecting portion 132 connected to the mating connector is exposed from the opening 111H. The case 101 has a cover 112 that is assembled to the main body 111 so as to cover the opening 111H. The cover 112 has a connector opening 112H that exposes the connector 130, and is assembled to the main body 111 so as to close the gap between the connector 130 and the inner edge of the opening 111H of the case 101.

ブラケット１は樹脂製であり、図１及び図２に示すように、ブラケット本体１０と、ケース１０１を組み付けるための組付け部２０と、を有する。 The bracket 1 is made of resin and has a bracket main body 10 and an assembling portion 20 for assembling the case 101 as shown in FIGS. 1 and 2.

ブラケット本体１０は、組付け部２０によってケース１０１が組み付けられた組み付け状態（図２参照）において、ケース１０１の主面１０１ｂと対面して配置される主面対向部３と、主面対向部３から主面１０１ｂ側へと延び出し、ケース１０１の外周側面１０１ａと対向する位置に配置される側面対向部２と、を有する。 The bracket main body 10 has a main surface facing portion 3 arranged to face the main surface 101b of the case 101 and a main surface facing portion 3 in an assembled state (see FIG. 2) in which the case 101 is assembled by the assembling portion 20. It has a side surface facing portion 2 which extends from the main surface 101b to the side and is arranged at a position facing the outer peripheral side surface 101a of the case 101.

主面対向部３は、図７及び図８に示すように、上記組み付け状態（図２参照）において、ケース１０１の主面１０１ｂと対面する主面３ａを有するとともに、その主面３ａから突出するリブ状の当て止め部３１と、その主面３ａから斜め方向に延び出し、組み付けられたケース１０１の主面１０１ｂを弾性的に押し付ける弾性押付片３２と、を有する。 As shown in FIGS. 7 and 8, the main surface facing portion 3 has a main surface 3a facing the main surface 101b of the case 101 in the assembled state (see FIG. 2), and protrudes from the main surface 3a. It has a rib-shaped retaining portion 31 and an elastic pressing piece 32 that extends obliquely from the main surface 3a and elastically presses the main surface 101b of the assembled case 101.

側面対向部２は、主面対向部３からその主面３ａ側に向かって、主面対向部３に直交する方向２００Ｚ（図４参照）へ延び出す形で形成されている。図１１に示すように、側面対向部２は、上記組み付け状態（図２参照）において、主面対向部３に対し主面３ａ側で対向する先端フレーム部２Ａと、ケース１０１の外周方向Ｓ（図２１参照）における一方の側で先端フレーム部２Ａと主面対向部３とを連結する第一の側方フレーム部２Ｂと、他方の側で先端フレーム部２Ａと主面対向部３とを連結する第二の側方フレーム部２Ｃと、外周方向Ｓの中央で先端フレーム部２Ａと主面対向部３とを連結する中央フレーム部２Ｄと、を有した枠形状を形成している。 The side surface facing portion 2 is formed so as to extend from the main surface facing portion 3 toward the main surface 3a side in a direction 200Z (see FIG. 4) orthogonal to the main surface facing portion 3. As shown in FIG. 11, in the assembled state (see FIG. 2), the side surface facing portion 2 has the tip frame portion 2A facing the main surface facing portion 3 on the main surface 3a side and the outer peripheral direction S of the case 101 (see FIG. 2). (See FIG. 21), the first side frame portion 2B that connects the tip frame portion 2A and the main surface facing portion 3 on one side, and the tip frame portion 2A and the main surface facing portion 3 are connected on the other side. A frame shape having a second lateral frame portion 2C and a central frame portion 2D connecting the tip frame portion 2A and the main surface facing portion 3 at the center of the outer peripheral direction S is formed.

組付け部２０は、図７及び図８に示すように、挿入部２１と、抜け止め係止部２２と、を有する。一方、ケース１０１は、図２３に示すように、その外周側面１０１ａ上に、挿入部２１が挿入される間隙１０２Ｇを形成する組付け部１０２を有する。組付け部２０は、この間隙１０２Ｇに挿入部２１を挿入させる形で、ケース１０１の組付け部１０２に対し組み付けられる。 As shown in FIGS. 7 and 8, the assembling portion 20 has an inserting portion 21 and a retaining locking portion 22. On the other hand, as shown in FIG. 23, the case 101 has an assembly portion 102 that forms a gap 102G into which the insertion portion 21 is inserted on the outer peripheral side surface 101a. The assembling portion 20 is assembled to the assembling portion 102 of the case 101 by inserting the inserting portion 21 into the gap 102G.

ケース１０１の組付け部１０２は、図２１及び図２２に示すように、外周側面１０１ａ上で互いがケース１０１の外周方向Ｓ（図２１参照）において対向する形で上方に向けて突出形成される対向壁部１０２Ｂ、１０２Ｂと、それら対向壁部１０２Ｂ、１０２Ｂの先端側から屈曲してケース１０１の外周方向側へと延び出す弾性押付部１０２Ａ、１０２Ａと、を有したＬ字状対向壁部である。両弾性押付部１０２Ａは、図２３の最下図に示すように、対向壁部１０２Ｂ側から外周側面１０１ａと平行をなして互いが接近する方向に延び出す弾性基端部１０２Ｑと、その弾性基端部１０２Ｑの先端側で外周側面１０１ａ側に向かうよう傾斜する弾性先端部１０２Ｐと、をそれぞれが有している。挿入部２１が挿入される間隙１０２Ｇは、対向壁部１０２Ｂ、１０２Ｂの対向間（図１３参照）で、なおかつ互いに接近するよう延び出す弾性押付部１０２Ａ、１０２Ａと外周側面１０１ａとの間（図１２Ａ及び図１２Ｂ参照）に形成されている。間隙１０２Ｇへの挿入部２１の挿入方向Ｉは、ここではケース１０１において組付け部１０２（弾性押付部１０２Ａ、１０２Ａ）を有する外周側面１０１ａに平行で、なおかつ外周方向Ｓ（図２１参照）に直交する方向とされている。他方、挿入部２１は板状に形成され、ケース１０１の組付け部１０２が形成する上記間隙１０２Ｇへと挿入されることにより、組付け部１０２に対し抜け止め状態となり、その結果、図２のようにブラケット１がケース１０１に組み付く。 As shown in FIGS. 21 and 22, the assembling portion 102 of the case 101 is formed so as to project upward on the outer peripheral side surface 101a so as to face each other in the outer peripheral direction S (see FIG. 21) of the case 101. An L-shaped facing wall portion having facing wall portions 102B and 102B and elastic pressing portions 102A and 102A that bend from the tip side of the facing wall portions 102B and 102B and extend toward the outer peripheral direction of the case 101. is there. As shown in the lowermost view of FIG. 23, both elastic pressing portions 102A have an elastic base end portion 102Q extending parallel to the outer peripheral side surface 101a from the facing wall portion 102B side and extending in a direction approaching each other, and an elastic base end thereof. Each has an elastic tip portion 102P that is inclined toward the outer peripheral side surface 101a side on the tip end side of the portion 102Q. The gap 102G into which the insertion portion 21 is inserted is between the facing wall portions 102B and 102B (see FIG. 13) and between the elastic pressing portions 102A and 102A extending so as to approach each other and the outer peripheral side surface 101a (FIG. 12A). And FIG. 12B). The insertion direction I of the insertion portion 21 into the gap 102G is parallel to the outer peripheral side surface 101a having the assembly portions 102 (elastic pressing portions 102A, 102A) in the case 101, and is orthogonal to the outer peripheral direction S (see FIG. 21). It is said to be the direction to do. On the other hand, the insertion portion 21 is formed in a plate shape and is inserted into the gap 102G formed by the assembly portion 102 of the case 101 to prevent the assembly portion 102 from coming off. As a result, FIG. The bracket 1 is assembled to the case 101 as described above.

挿入部２１は、組み付け状態にあるブラケット１の側面対向部２において、ケース１０１の外周側面１０１ａに近い側に位置し（図２参照）、主面対向部３からその直交方向２００Ｚ（図１２Ａ参照）に延出形成されている。また、挿入部２１は、図７及び図８に示すように、中央フレーム部２Ｄにおける外周方向Ｓ（図２１参照）の一方の側（即ち、第一の側方フレーム部２Ｂ側）と他方の側（即ち、第二の側方フレーム部２Ｃ側）で、ケース１０１の外周側面１０１ａに向かう下方向へと延び出す基端壁部２４、２４の先端側から、互いに離間する方向へとそれぞれ延び出した板状壁部であり、互いに離間する方向へと延び出した先の先端面２１ｂ、２１ｂ（挿入部２１の両側面２１ｂ、２１ｂともいう）には、図１１に示すように、摺動突起部２１Ｔが形成されている。 The insertion portion 21 is located on the side facing portion 2 of the bracket 1 in the assembled state near the outer peripheral side surface 101a of the case 101 (see FIG. 2), and is 200Z orthogonal to the main surface facing portion 3 (see FIG. 12A). ) Is extended. Further, as shown in FIGS. 7 and 8, the insertion portion 21 is one side (that is, the first side frame portion 2B side) of the outer peripheral direction S (see FIG. 21) in the central frame portion 2D and the other. On the side (that is, the second side frame portion 2C side), the base end wall portions 24, 24 extending downward toward the outer peripheral side surface 101a of the case 101 extend in directions away from each other. As shown in FIG. 11, it slides on the tip surfaces 21b and 21b (also referred to as both side surfaces 21b and 21b of the insertion portion 21), which are the protruding plate-shaped wall portions and extend in the direction of being separated from each other. The protrusion 21T is formed.

摺動突起部２１Ｔは、図１１及び図１３に示すように、上記間隙１０２Ｇへの挿入部２１の挿入に際して対向壁部１０２Ｂ、１０２Ｂと対面する挿入部２１の両側の側面２１ｂ、２１ｂに、それぞれ突出形成された円弧状の突出部である。これら摺動突起部２１Ｔは、間隙１０２Ｇへの挿入部２１の挿入に際して、上記対向壁部１０２Ｂ、１０２Ｂに対し面接触というよりも点接触に近い形で押し付けられるから、接触面積が小さく、挿入部２１の挿入抵抗を大きく減じることができる。これにより、ブラケット１とケース１０１の組み付けが容易になっている。 As shown in FIGS. 11 and 13, the sliding protrusions 21T are provided on the side surfaces 21b and 21b on both sides of the insertion portions 21 facing the facing wall portions 102B and 102B when the insertion portion 21 is inserted into the gap 102G, respectively. It is an arc-shaped protrusion formed by a protrusion. When the insertion portion 21 is inserted into the gap 102G, these sliding protrusions 21T are pressed against the facing wall portions 102B and 102B in a form closer to point contact rather than surface contact, so that the contact area is small and the insertion portion is inserted. The insertion resistance of 21 can be greatly reduced. This facilitates the assembly of the bracket 1 and the case 101.

ここでの摺動突起部２１Ｔは、図１１に示すように、当該両側の側面２１ｂ、２１ｂのうちの一方の側（即ち、第一の側方フレーム部２Ｂ側）の側面２１ｂに２つ、その逆の他方の側（即ち、第二の側方フレーム部２Ｃ側）の側面２１ｂに１つ、合わせて３つ形成されている。それら３つの摺動突起部２１Ｔによって対向壁部１０２Ｂ、１０２Ｂと３点で接触することにより、挿入によってケース１０１に組み付けられたブラケット１は、当該ケース１０１に対しそれら３点を通過する平面内における任意の方向への移動が全て規制されたガタつき防止状態となる。 As shown in FIG. 11, two sliding protrusions 21T are provided on the side surface 21b of one of the side surfaces 21b and 21b on both sides (that is, the first side frame portion 2B side). A total of three are formed on the side surface 21b on the opposite side (that is, the second side frame portion 2C side). The bracket 1 assembled to the case 101 by insertion by contacting the facing wall portions 102B and 102B at three points by the three sliding protrusions 21T is in a plane passing through these three points with respect to the case 101. All movements in any direction are restricted to prevent rattling.

また、挿入部２１は、上記間隙１０２Ｇに挿入される際に、その上面２１ａが弾性押付部１０２Ａによって下方に押し付けられる。ここでの上面２１ａは、図１２Ａに示すように、挿入部２１の挿入方向Ｉにおける後方側上面２１ａ３と、その後方側上面２１ａ３から挿入方向Ｉの前方に向かって下る中間斜面２１ａ２と、その中間斜面２１ａ２から挿入方向Ｉの前方に向かって延びて後方側上面２１ａ３よりも下側に位置する前方側上面２１ａ１と、を有し、更にその前方側上面２１ａ１の挿入方向Ｉの前方に上記ガイド斜面をなす前端上面２１ａ０を有している。挿入部２１が上記間隙１０２Ｇに挿入される際、弾性押付部１０２Ａは、これら上面２１ａ０、２１ａ１、２１ａ２、２１ａ３を挿入方向Ｉにおける前方側から後方側へと順に摺動していく。さらにいえば、挿入部２１は、上面２１ａの裏の底面が平坦に形成されているから、これら上面２１ａ０、２１ａ１、２１ａ２、２１ａ３に応じて、挿入方向Ｉにおける前方側ほど薄い形状になっている。なお、これら上面２１ａ０、２１ａ１、２１ａ２、２１ａ３は、少なくとも弾性押付部１０２Ａが摺動する領域に形成されていればよく、残余の領域は同様の形状でなくともよい。ここでは挿入部２１における弾性基端部１０２Ｂと対向する面領域が、最も厚みのある上面２１ａ３の領域と同じ厚みで形成されている。 Further, when the insertion portion 21 is inserted into the gap 102G, its upper surface 21a is pressed downward by the elastic pressing portion 102A. As shown in FIG. 12A, the upper surface 21a here is the rear upper surface 21a3 in the insertion direction I of the insertion portion 21, the intermediate slope 21a2 descending from the rear upper surface 21a3 toward the front in the insertion direction I, and the middle thereof. The guide slope has a front upper surface 21a1 extending from the slope 21a2 toward the front in the insertion direction I and located below the rear upper surface 21a3, and further in front of the front upper surface 21a1 in the insertion direction I. It has a front end upper surface 21a0 forming the above. When the insertion portion 21 is inserted into the gap 102G, the elastic pressing portion 102A slides the upper surfaces 21a0, 21a1, 21a2, 21a3 in order from the front side to the rear side in the insertion direction I. Furthermore, since the bottom surface of the back surface of the upper surface 21a is formed flat, the insertion portion 21 has a thinner shape toward the front side in the insertion direction I according to the upper surfaces 21a0, 21a1, 21a2, and 21a3. .. The upper surfaces 21a0, 21a1, 21a2, and 21a3 may be formed at least in a region where the elastic pressing portion 102A slides, and the remaining region does not have to have the same shape. Here, the surface region of the insertion portion 21 facing the elastic base end portion 102B is formed to have the same thickness as the region of the thickest upper surface 21a3.

また、摺動突起部２１Ｔは、図１３に示すように、挿入方向Ｉに向かって、挿入部２１の両側の側面２１ｂ、２１ｂに交互に現れるよう形成されている。ここでの摺動突起部２１Ｔは、図１１に示すように、挿入部２１の一方の側面２１ｂ上で前方側上面２１ａ１に対応する区間に１つ、挿入部２１の他方の側面２１ｂ上で中間斜面２１ａ２に対応する区間に１つ、挿入部２１の一方の側面２１ｂ上で後方側上面２１ａ３に対応する区間に１つ形成されている。 Further, as shown in FIG. 13, the sliding protrusions 21T are formed so as to appear alternately on the side surfaces 21b and 21b on both sides of the insertion portion 21 in the insertion direction I. As shown in FIG. 11, there is one sliding protrusion 21T on one side surface 21b of the insertion portion 21 in a section corresponding to the front upper surface 21a1 and an intermediate portion on the other side surface 21b of the insertion portion 21. One is formed in the section corresponding to the slope 21a2, and one is formed in the section corresponding to the rear upper surface 21a3 on one side surface 21b of the insertion portion 21.

抜け止め係止部２２は、図１１に示すように、側面対向部２において挿入部２１の挿入方向Ｉの前方側で、ケース１０１の外周側面１０１ａへの接近方向である下方に向かって突出形成される。挿入部２１は、側面対向部２においてこの抜け止め係止部２２よりも下側に位置するとともに、自身の挿入方向Ｉの前方側端部２１Ａが抜け止め係止部２２よりも挿入方向Ｉの後方側に位置している。 As shown in FIG. 11, the retaining locking portion 22 is formed so as to project downward on the side facing portion 2 on the front side of the inserting portion 21 in the insertion direction I, which is the approaching direction to the outer peripheral side surface 101a of the case 101. Will be done. The insertion portion 21 is located below the retaining locking portion 22 in the side surface facing portion 2, and the front end portion 21A of its own insertion direction I is located in the insertion direction I with respect to the retaining locking portion 22. It is located on the rear side.

ここでの抜け止め係止部２２は、図８に示すように、側面対向部２の先端フレーム部２Ａにおいて下方に突出する形で形成されている。具体的にいえば、図１１、図７、図８に示すように、抜け止め係止部２２は、先端フレーム部２Ａにおいて、中央フレーム部２Ｄが接続する中央接続部２ＡＤと側方フレーム部２Ｂ、２Ｃが接続する側方接続部２ＡＢ、２ＡＣとの間の区間に形成されている。さらにいえば、図１０に示すように、抜け止め係止部２２は、先端フレーム部２Ａにおける中央接続部２ＡＤと側方接続部２ＡＢ、２ＡＣとの間の区間の中央に形成されている。一方で、それら区間中央の両側には、抜け止め係止部２２が非形成とされており、この部分が脆弱部２ＡＥ、２ＡＥ（図１４参照）とされている。つまり、先端フレーム部２Ａにおいて、抜け止め係止部２２が形成された中央区間や他のフレーム部２Ｂ、２Ｃ、２Ｄとの接続部２ＡＢ、２ＡＣ、２ＡＤが形成される両端区間は、いずれも剛性の高い高剛性部として形成される一方、それら抜け止め係止部２２や接続部２ＡＢ、２ＡＣ、２ＡＤが非形成の区間は、それら高剛性部よりも剛性が低く弾性変形の生じやすい脆弱部２ＡＥとして形成されている。 As shown in FIG. 8, the retaining locking portion 22 here is formed so as to project downward at the tip frame portion 2A of the side facing portion 2. Specifically, as shown in FIGS. 11, 7, and 8, the retaining locking portion 22 is the central connecting portion 2AD and the side frame portion 2B to which the central frame portion 2D is connected in the tip frame portion 2A. 2C is formed in the section between the side connecting portions 2AB and 2AC to which the 2C is connected. Further, as shown in FIG. 10, the retaining locking portion 22 is formed in the center of the section between the central connecting portion 2AD and the side connecting portions 2AB and 2AC in the tip frame portion 2A. On the other hand, retaining locking portions 22 are not formed on both sides of the center of these sections, and these portions are fragile portions 2AE and 2AE (see FIG. 14). That is, in the tip frame portion 2A, the central section in which the retaining locking portion 22 is formed and the both end sections in which the connecting portions 2AB, 2AC, and 2AD with the other frame portions 2B, 2C, and 2D are formed are both rigid. In the section where the retaining locking portion 22 and the connecting portions 2AB, 2AC, and 2AD are not formed, the fragile portion 2AE is less rigid than the high-rigidity portion and is prone to elastic deformation. Is formed as.

抜け止め係止部２２は、ケース１０１との組み付け状態（図２参照）においては、ケース１０１にて所定の係止部をなす組付け部１０２に対し係止し、ケース１０１を抜け止め状態に保持する。具体的にいえば、抜け止め係止部２２は、上記弾性押付部１０２Ａと外周側面１０１ａとの間の間隙１０２Ｇに挿入部２１が所定の組み付け位置まで挿入された際に、弾性押付部１０２Ａに対し挿入部２１の挿入方向Ｉの前方側に回り込んで、弾性押付部１０２Ａの前方側端面１０２ａに対し係止される（図１２Ｂの下図参照）。 In the assembling state with the case 101 (see FIG. 2), the retaining locking portion 22 is locked to the assembling portion 102 forming a predetermined locking portion in the case 101, and the case 101 is brought into the retaining state. Hold. Specifically, the retaining locking portion 22 is inserted into the elastic pressing portion 102A when the inserting portion 21 is inserted into the gap 102G between the elastic pressing portion 102A and the outer peripheral side surface 101a to a predetermined assembly position. On the other hand, the insertion portion 21 wraps around the front side in the insertion direction I and is locked to the front end surface 102a of the elastic pressing portion 102A (see the lower figure of FIG. 12B).

このようにブラケット１は、ケース１０１の外周側面１０１ａ上で、Ｌ字状対向壁部をなす組付け部１０２によって形成される間隙１０２Ｇに、挿入部２１を挿入させることで、当該組付け部１０２を抜け止め係止部２２が係止した抜け止め状態となることにより、ケース１０１に対し組み付けられる。 In this way, the bracket 1 is formed by inserting the insertion portion 21 into the gap 102G formed by the assembling portion 102 forming the L-shaped facing wall portion on the outer peripheral side surface 101a of the case 101. When the retaining locking portion 22 is locked, the case 101 can be assembled.

ここで、組付け部２０によるブラケット１とケース１０１（ＥＣＵ１００）との組み付け方法及び組み付け構造１０００について、具体的に説明する。 Here, the method of assembling the bracket 1 and the case 101 (ECU 100) by the assembling unit 20 and the assembling structure 1000 will be specifically described.

既に述べたように、ブラケット１とケース１０１との組み付けは、図１２Ａと図１２Ｂと図１３とに示すように、ブラケット１の挿入部２１を、ケース１０１の組付け部１０２に設けられた間隙１０２Ｇ（第一対向間）に挿入することによってなされる。ただし、この挿入に際しては、ケース１０１の間隙１０２Ｇを形成する弾性押付部１０２Ａに、ブラケット１の抜け止め係止部２２と挿入部２１との対向間２０Ｇ（第二対向間：図１２Ａの上図参照）を通過させる必要があるが、図１２Ａの上図に示すように、ブラケット１の挿入部２１をそのままケース１０１の間隙１０２Ｇに挿入しようとしても、ブラケット１の抜け止め係止部２２とケース１０１の弾性押付部１０２Ａとが当接して、ケース１０１の弾性押付部１０２Ａはブラケット１の上記対向間２０Ｇに進入できない。このため、ブラケット１の挿入部２１も、ケース１０１の間隙１０２Ｇに進入できず、ブラケット１とケース１０１は組み付かない。 As described above, in the assembling of the bracket 1 and the case 101, as shown in FIGS. 12A, 12B and 13, the insertion portion 21 of the bracket 1 is inserted into the gap provided in the assembling portion 102 of the case 101. It is done by inserting it into 102G (between the first facing). However, at the time of this insertion, the elastic pressing portion 102A forming the gap 102G of the case 101 is 20G between the retaining locking portion 22 of the bracket 1 and the insertion portion 21 facing each other (second facing gap: upper view of FIG. 12A). It is necessary to pass through (see), but as shown in the upper figure of FIG. 12A, even if the insertion portion 21 of the bracket 1 is to be inserted into the gap 102G of the case 101 as it is, the retaining locking portion 22 of the bracket 1 and the case The elastic pressing portion 102A of the case 101 comes into contact with the elastic pressing portion 102A of the case 101, and the elastic pressing portion 102A of the case 101 cannot enter the opposed space 20G of the bracket 1. Therefore, the insertion portion 21 of the bracket 1 cannot enter the gap 102G of the case 101, and the bracket 1 and the case 101 cannot be assembled.

ところが、図１２Ａの中央図及び下図に示すように、上記当接状態のブラケット１の組付け部２０を、ケース１０１の弾性押付部１０２Ａに押し付けて、側面対向部２と組付け部２０と弾性押付部１０２Ａとのいずれか又は複数を弾性変形させることで、ケース１０１の弾性押付部１０２Ａをブラケット１の上記対向間２０Ｇ（第二対向間）に進入可能となり、これによりブラケット１の挿入部２１もケース１０１の上記間隙１０２Ｇ（第一対向間）に挿入可能になる。具体的にいえば、主に以下の３つの弾性変形が生じて、上記対向間２０Ｇに弾性押付部１０２Ａが進入可能になる。 However, as shown in the central view and the lower figure of FIG. 12A, the assembling portion 20 of the bracket 1 in the contact state is pressed against the elastic pressing portion 102A of the case 101, and the side facing portion 2 and the assembling portion 20 are elastic. By elastically deforming one or more of the pressing portion 102A, the elastic pressing portion 102A of the case 101 can enter the opposed space 20G (second facing space) of the bracket 1, whereby the insertion portion 21 of the bracket 1 can be inserted. Can also be inserted into the gap 102G (between the first facing surfaces) of the case 101. Specifically, the following three elastic deformations mainly occur, and the elastic pressing portion 102A can enter the facing space 20G.

第一の弾性変形は、側面対向部２の弾性変形であり、図１４に示すように、挿入方向Ｉ側に向かうブラケット１の抜け止め係止部２２が、弾性押付部１０２Ａによって押し上げられる弾性変形である。この第一の弾性変形は、先端フレーム部２Ａにおいて抜け止め係止部２２の両側の脆弱部２ＡＥ、２ＡＥにおいて生じる弾性変形であり、それら脆弱部２ＡＥが弾性変形することで、先端フレーム部２Ａの中央が押し上げられる。その結果、ブラケット１の抜け止め係止部２２と挿入部２１との対向間２０Ｇ（図１２Ａ参照）が拡がり、当該対向間２０Ｇに弾性押付部１０２Ａが進入しやすくなる。 The first elastic deformation is the elastic deformation of the side surface facing portion 2, and as shown in FIG. 14, the elastic deformation of the bracket 1 retaining locking portion 22 toward the insertion direction I side is pushed up by the elastic pressing portion 102A. Is. This first elastic deformation is elastic deformation that occurs in the fragile portions 2AE and 2AE on both sides of the retaining locking portion 22 in the tip frame portion 2A, and the elastic deformation of these fragile portions 2AE causes the tip frame portion 2A to be elastically deformed. The center is pushed up. As a result, the space between the retaining locking portion 22 of the bracket 1 and the insertion portion 21 facing each other (see FIG. 12A) expands, and the elastic pressing portion 102A easily enters the facing space 20G.

第二の弾性変形は、弾性押付部１０２Ａの弾性変形であり、図１２Ａの下図に示すように、弾性押付部１０２Ａの先端側の弾性先端部１０２Ｐが、その下側に入り込むブラケット１の挿入部２１によって押し上げられる弾性変形である。この第二の弾性変形は、弾性押付部１０２Ａの先端側で下方に下る傾斜片として形成されている弾性先端部１０２Ｐにおいて生じる弾性変形である。弾性押付部１０２Ａは、弾性先端部１０２Ｐが押し上げられることで、弾性基端部１０２Ｑを含む弾性押付部１０２Ａ全体が直線状に近づいて厚み方向の幅が狭くなり、その結果、ブラケット１の抜け止め係止部２２と挿入部２１との対向間２０Ｇに進入しやすい形状になる。 The second elastic deformation is the elastic deformation of the elastic pressing portion 102A, and as shown in the lower figure of FIG. 12A, the insertion portion of the bracket 1 in which the elastic tip portion 102P on the tip side of the elastic pressing portion 102A enters the lower side thereof. It is an elastic deformation pushed up by 21. This second elastic deformation is an elastic deformation that occurs in the elastic tip portion 102P formed as an inclined piece that descends downward on the tip side of the elastic pressing portion 102A. In the elastic pressing portion 102A, when the elastic tip portion 102P is pushed up, the entire elastic pressing portion 102A including the elastic base end portion 102Q approaches a straight line and the width in the thickness direction becomes narrow, and as a result, the bracket 1 is prevented from coming off. The shape is such that it is easy to enter 20G between the locking portion 22 and the inserting portion 21 facing each other.

第三の弾性変形は、組付け部２０の弾性変形であり、図１２Ａの下図に示すように、弾性押付部１０２Ａによってブラケット１の挿入部２１が押し下げられる弾性変形である。この第三の弾性変形は、挿入部２１において挿入方向Ｉの前方側から生じる弾性変形である。挿入部２１は、弾性先端部１０２Ｐが接触してくる挿入方向Ｉの前方側から押し下げられていき、これにより、ブラケット１における抜け止め係止部２２と挿入部２１との対向間２０Ｇが拡がって、当該対向間２０Ｇに弾性押付部１０２Ａが進入しやすくなる。弾性押付部１０２Ａに対し最初に接触する挿入部２１の挿入方向Ｉの前方側は、上面２１ａ０、２１ａ１が形成されている比較的薄い部分（図１２Ａの上図参照）であり、弾性変形が生じやすい。 The third elastic deformation is the elastic deformation of the assembling portion 20, and as shown in the lower figure of FIG. 12A, the elastic deformation is such that the insertion portion 21 of the bracket 1 is pushed down by the elastic pressing portion 102A. This third elastic deformation is an elastic deformation that occurs from the front side of the insertion direction I in the insertion portion 21. The insertion portion 21 is pushed down from the front side in the insertion direction I in which the elastic tip portion 102P comes into contact, whereby the gap between the retaining locking portion 22 and the insertion portion 21 in the bracket 1 is expanded by 20G. , The elastic pressing portion 102A easily enters the facing space 20G. The front side of the insertion direction I of the insertion portion 21 that first contacts the elastic pressing portion 102A is a relatively thin portion where the upper surfaces 21a0 and 21a1 are formed (see the upper view of FIG. 12A), and elastic deformation occurs. Cheap.

第一、第二、第三の弾性変形を生じさせる手順について説明する。 The procedure for causing the first, second, and third elastic deformations will be described.

まずは図１２Ａの中央図に示すように、弾性押付部１０２Ａを、ブラケット１における上側の抜け止め係止部２２と下側の挿入部２１との間となる対向間２０Ｇ（第二対向間）から、挿入部２１の挿入方向Ｉとは逆向きに進入させ、対向間２０Ｇの奥に受け入れる。当該受け入れの際には、その受け入れ方向Ｊ（挿入方向Ｉとは逆方向）の前方側が上側で後方側が下側となるようケース１０１をブラケット１に対し傾斜させる。そして、その傾斜したケース１０１を、受け入れ方向Ｊ側に向かってその傾斜方向Ｋ１に移動させて、弾性押付部１０２Ａを第二対向間２０Ｇに進入させる。つまり、弾性押付部１０２Ａを、抜け止め係止部２２の下側から斜め上方（図中では左上方向）に向かう形で、上記対向間２０Ｇに接近させていく。 First, as shown in the central view of FIG. 12A, the elastic pressing portion 102A is inserted from the facing space 20G (second facing space) between the upper retaining locking portion 22 and the lower inserting portion 21 in the bracket 1. , The insertion portion 21 is made to enter in the direction opposite to the insertion direction I, and is received in the depth of 20G between the opposing portions. At the time of the acceptance, the case 101 is tilted with respect to the bracket 1 so that the front side in the acceptance direction J (the direction opposite to the insertion direction I) is the upper side and the rear side is the lower side. Then, the inclined case 101 is moved toward the receiving direction J side in the inclined direction K1 to allow the elastic pressing portion 102A to enter the second facing 20G. That is, the elastic pressing portion 102A is brought closer to the facing space 20G in a form of obliquely upward (upper left direction in the drawing) from the lower side of the retaining locking portion 22.

そうすると、図１２Ａの下図に示すように、挿入部２１の前端上面２１ａ０に対し弾性押付部１０２Ａが当接する。ここでの挿入部２１の前端上面２１ａ０は、挿入方向Ｉの前方側に向かって下るガイド斜面として形成されているから、弾性押付部１０２Ａは、当該前端上面２１ａ０に当接した際に、挿入部２１が挿入方向Ｉの奥へと押し込まれると、そのまま当該前端上面２１ａ０上を上記受け入れ方向Ｊ側に摺動していく。このとき、弾性押付部１０２Ａは、摺動する前端上面２１ａ０を下方に押し下げ、かつ上側に位置する抜け止め係止部２２を上方へ押し上げるから、これにより、上記の第一と第三の弾性変形（図１２Ａの下図及び図１４参照）が生じ、ブラケット１の対向間２０Ｇが押し拡げられる。 Then, as shown in the lower figure of FIG. 12A, the elastic pressing portion 102A comes into contact with the front end upper surface 21a0 of the insertion portion 21. Since the front end upper surface 21a0 of the insertion portion 21 here is formed as a guide slope that descends toward the front side in the insertion direction I, the elastic pressing portion 102A comes into contact with the front end upper surface 21a0 of the insertion portion 21. When 21 is pushed into the back of the insertion direction I, it slides on the upper surface 21a0 of the front end as it is toward the receiving direction J side. At this time, the elastic pressing portion 102A pushes down the sliding front end upper surface 21a0 and pushes up the retaining locking portion 22 located on the upper side. (See the lower figure and FIG. 14 of FIG. 12A) occurs, and the facing 20G of the bracket 1 is expanded.

一方で、このときの弾性押付部１０２Ａは、図１４に示すように、上側に位置する抜け止め係止部２２から弾性基端部１０２Ｑに対する下方への押し付けと、下側に位置する挿入部２１から弾性先端部１０２Ｐに対する上方への押し付けとの双方を受けることになり、基端側の弾性基端部１０２Ｑが下方に沈み、先端側の弾性先端部１０２Ｐが上方に押し上がる上記の第二の弾性変形が生じる。その結果、弾性押付部１０２Ａは、全体の厚み方向の幅が狭くなる。厚み方向の幅が狭くなった弾性押付部１０２Ａは、ブラケット１の対向間２０Ｇを拡げる上記第一と第三の弾性変形がそれほど大きく生じなくても、対向間２０Ｇの奥へと進入可能になる。 On the other hand, as shown in FIG. 14, the elastic pressing portion 102A at this time is pressed downward from the retaining locking portion 22 located on the upper side to the elastic base end portion 102Q, and the insertion portion 21 located on the lower side. The elastic tip 102Q on the proximal end side sinks downward, and the elastic tip 102P on the distal end side is pushed upward. Elastic deformation occurs. As a result, the width of the elastic pressing portion 102A in the thickness direction of the whole becomes narrow. The elastic pressing portion 102A having a narrowed width in the thickness direction can enter the depth of the facing space 20G even if the first and third elastic deformations that expand the facing space 20G of the bracket 1 do not occur so much. ..

このようにして、ブラケット１の対向間２０Ｇ（第二対向間）に弾性押付部１０２Ａを受け入れ可能とし、弾性押付部１０２Ａを、上記受け入れ方向Ｊ側に移動させて当該対向間２０Ｇ（第二対向間）の奥へと進入させることにより、ブラケット１の挿入部２１は、ケース１０１の間隙１０２Ｇ（第一対向間）へと挿入されていく。図１３に示すように、ブラケット１の挿入部２１の間隙１０２Ｇへの挿入は、挿入部２１の両側の側面２１ｂ、２１ｂに形成された摺動突起部２１Ｔが、ケース１０１の対向壁部１０２Ｂ、１０２Ｂの内側壁面１０２ｂ上を摺動する形でなされる。更に、挿入部２１の間隙１０２Ｇへの挿入は、図１２Ｂの中央図及び下図と図１４に示すように、ケース１０１の弾性押付部１０２Ａを、挿入部２１の上面２１ａに押し付け、当該上面２１ａ上で摺動させる形でなされる。 In this way, the elastic pressing portion 102A can be received in the facing space 20G (second facing space) of the bracket 1, and the elastic pressing portion 102A is moved to the receiving direction J side so that the facing space 20G (second facing space) is received. The insertion portion 21 of the bracket 1 is inserted into the gap 102G (between the first facing surfaces) of the case 101 by advancing into the depth of the space). As shown in FIG. 13, when the insertion portion 21 of the bracket 1 is inserted into the gap 102G, the sliding protrusions 21T formed on the side surfaces 21b and 21b on both sides of the insertion portion 21 are formed on the facing wall portion 102B of the case 101. It is made by sliding on the inner wall surface 102b of 102B. Further, the insertion portion 21 is inserted into the gap 102G by pressing the elastic pressing portion 102A of the case 101 against the upper surface 21a of the insertion portion 21 and above the upper surface 21a, as shown in the central view of FIG. It is made by sliding with.

その後、図１２Ｂの下図及び図１３の右上図に示すように、弾性押付部１０２Ａ全体が抜け止め係止部２２を通り過ぎ、その受け入れが完了すると、上記の第一から第三の弾性変形が全て解除され（即ち、弾性復帰して）、挿入部２１は所定の組み付け位置に到達する。これにより、ブラケット１は、ケース１０１に対し組み付けられた状態となる。具体的にいえば、第一の弾性変形が解除されることにより、抜け止め係止部２２が弾性押付部１０２Ａに対し挿入方向Ｉの後方側に回り込んで係止した状態となって、弾性押付部１０２Ａの挿入方向Ｉの逆向き（即ち、挿入方向Ｉの後方側）への抜けを阻止された抜け止め状態となる。これにより、ブラケット１がケース１０１に対し組み付く。 After that, as shown in the lower figure of FIG. 12B and the upper right figure of FIG. 13, when the entire elastic pressing portion 102A passes through the retaining locking portion 22 and its acceptance is completed, all the above-mentioned first to third elastic deformations are completed. After being released (that is, elastically restored), the insertion portion 21 reaches a predetermined assembly position. As a result, the bracket 1 is in a state of being assembled to the case 101. Specifically, when the first elastic deformation is released, the retaining locking portion 22 wraps around the elastic pressing portion 102A toward the rear side in the insertion direction I and is locked to the elastic pressing portion 102A. The pressing portion 102A is in a retaining state in which the insertion direction I is prevented from coming out in the opposite direction (that is, the rear side of the insertion direction I). As a result, the bracket 1 is assembled to the case 101.

なお、弾性押付部１０２Ａに関する上述の第二及び第三の弾性変形は、ここでは上記抜け止め状態となったときに完全に解除されるとしているが、挿入部２１の上面２１ａ（具体的にいえば後方側上面２１ａ３）に対しては当接した状態となっている。ただし、上記抜け止め状態において、上述の第二の弾性変形及び第三の弾性変形のいずれか又は双方が、わずかに残った状態であってもよい。 The above-mentioned second and third elastic deformations related to the elastic pressing portion 102A are said to be completely released here when the above-mentioned retaining state is reached, but the upper surface 21a of the insertion portion 21 (specifically speaking). For example, it is in contact with the rear upper surface 21a3). However, in the retaining state, either or both of the second elastic deformation and the third elastic deformation described above may be slightly left.

このようにしてケース１０１に対し抜け止め状態となったブラケット１は、図４に示すように、上記所定の組み付け位置に保持される。上記組み付け位置に保持されたブラケット１は、上記組み付け位置を更に越えて、主面対向部３をケース１０１側へとさらに接近させることが可能である。ただし、その接近は、ブラケット１の主面対向部３に形成される当て止め部３１と弾性押付片３２とによって規制される。 As shown in FIG. 4, the bracket 1 that has been prevented from coming off from the case 101 is held at the predetermined assembly position. The bracket 1 held at the assembly position can further move the main surface facing portion 3 closer to the case 101 side beyond the assembly position. However, the approach is regulated by the retaining portion 31 and the elastic pressing piece 32 formed on the main surface facing portion 3 of the bracket 1.

当て止め部３１は、上記抜け止め状態において、ブラケット１の主面対向部３と対面するケース１０１の主面１０１ｂに対し近接対向する。この当て止め部３１は、ブラケット１が挿入方向Ｉの奥側に過剰に移動した際に当接して、それ以上の移動を規制する。 The padding portion 31 faces the main surface 101b of the case 101 facing the main surface facing portion 3 of the bracket 1 in the above-mentioned retaining state. When the bracket 1 is excessively moved to the back side in the insertion direction I, the retaining portion 31 comes into contact with the bracket 1 to restrict further movement.

弾性押付片３２は、上記抜け止め状態において、ブラケット１の主面対向部３と対面するケース１０１の主面１０１ｂを挿入方向Ｉの逆向きに常に押し付けるよう弾性変形している（図４参照）。これにより、ケース１０１は、組付け部１０２（ここでは弾性押付部１０２Ａ）が抜け止め係止部２２に係止（接触）した状態に保持している。 The elastic pressing piece 32 is elastically deformed so as to always press the main surface 101b of the case 101 facing the main surface facing portion 3 of the bracket 1 in the opposite direction of the insertion direction I in the retaining state (see FIG. 4). .. As a result, the case 101 is held in a state in which the assembling portion 102 (here, the elastic pressing portion 102A) is locked (contacted) with the retaining locking portion 22.

次に、上述のようにブラケット１の挿入部２１をケース１０１の間隙１０２Ｇに挿入する際の挿入抵抗について説明する。 Next, the insertion resistance when the insertion portion 21 of the bracket 1 is inserted into the gap 102G of the case 101 as described above will be described.

挿入部２１の間隙１０２Ｇへの挿入に伴い発生する挿入抵抗は、図１５の曲線Ｚに示すように、上述の第一から第三の弾性変形が生じる際に最初のピークＺ１を迎える。そして、間隙１０２Ｇに対し挿入部２１の２つ目の摺動突起部２１Ｔが進入した際に第二のピークＺ２を迎え、ケース１０１の弾性押付部１０２Ａが中間斜面２１ａ２から後方側上面２１ａ３に乗り上げる際に第三のピークＺ３を迎え、間隙１０２Ｇに対し挿入部２１の３つ目の摺動突起部２１Ｔが進入した際に第四のピークＺ４を迎える。 As shown in the curve Z of FIG. 15, the insertion resistance generated by the insertion of the insertion portion 21 into the gap 102G reaches the first peak Z1 when the above-mentioned first to third elastic deformations occur. Then, when the second sliding protrusion 21T of the insertion portion 21 enters the gap 102G, the second peak Z2 is reached, and the elastic pressing portion 102A of the case 101 rides on the rear upper surface 21a3 from the intermediate slope 21a2. At that time, the third peak Z3 is reached, and when the third sliding protrusion 21T of the insertion portion 21 enters the gap 102G, the fourth peak Z4 is reached.

なお、図１５の曲線Ａは、上述の第一から第三の弾性変形によって生じる挿入抵抗値であり、曲線Ｂは、２つ目の摺動突起部２１Ｔが間隙１０２Ｇに進入することにより生じる挿入抵抗値であり、曲線Ｃは、弾性押付部１０２Ａが中間斜面２１ａ２から後方側上面２１ａ３に乗り上げることにより生じる挿入抵抗値であり、曲線Ｄは、３つ目の摺動突起部２１Ｔが間隙１０２Ｇに進入することにより挿入抵抗値であり、曲線Ｚは、それらの挿入抵抗値を合成した挿入抵抗値である。いずれの曲線Ａ、Ｂ、Ｃ、Ｄ、Ｚもそれぞれの挿入抵抗の傾向が反映されるよう簡易的に示したものにすぎず、具体的な挿入抵抗値が反映されたものではない。 The curve A in FIG. 15 is the insertion resistance value caused by the above-mentioned first to third elastic deformations, and the curve B is the insertion caused by the second sliding protrusion 21T entering the gap 102G. The resistance value, the curve C is the insertion resistance value generated by the elastic pressing portion 102A riding on the upper surface 21a3 on the rear side from the intermediate slope 21a2, and the curve D is the insertion resistance value generated by the third sliding protrusion 21T in the gap 102G. It is the insertion resistance value by entering, and the curve Z is the insertion resistance value obtained by combining those insertion resistance values. All of the curves A, B, C, D, and Z are merely shown so as to reflect the tendency of each insertion resistance, and do not reflect a specific insertion resistance value.

図１５の曲線Ａに示すように、第一から第三の弾性変形により生じる挿入抵抗は、ケース１０１の弾性押付部１０２Ａがブラケット１の挿入部２１の前端上面２１ａ０上を摺動していく際に増大していき、前方側上面２１ａ１に達した際にピークａを迎え、その後、なだらかに減少していく。第一から第三の弾性変形による挿入抵抗のピークａは、図１４のように、抜け止め係止部２２と挿入部２１との対向間２０Ｇに弾性押付部１０２Ａが進入可能となった時、即ち上述の第一及び第二の弾性変形が最大変位で生じた時であり、その後、ブラケット１は、その弾性変形状態を保ちながら挿入部２１をケース１０１の間隙１０２Ｇに摺動させていく引き摺り抵抗を受け続ける。 As shown in the curve A of FIG. 15, the insertion resistance generated by the first to third elastic deformations occurs when the elastic pressing portion 102A of the case 101 slides on the front end upper surface 21a0 of the insertion portion 21 of the bracket 1. When it reaches the front upper surface 21a1, it reaches the peak a, and then gradually decreases. The peak a of the insertion resistance due to the first to third elastic deformations is determined when the elastic pressing portion 102A can enter the space 20G between the retaining locking portion 22 and the insertion portion 21 as shown in FIG. That is, when the above-mentioned first and second elastic deformations occur at the maximum displacement, after that, the bracket 1 slides the insertion portion 21 into the gap 102G of the case 101 while maintaining the elastic deformation state. Continue to receive resistance.

図１５の曲線Ｂに示すように、２つ目の摺動突起部２１Ｔにより生じる挿入抵抗は、挿入方向Ｉにおいてブラケット１の挿入部２１の両側面２１ｂ、２１ｂに交互に形成された摺動突起部２１Ｔのうち、挿入方向Ｉの前方側から数えて２つ目の摺動突起部２１Ｔが、ケース１０１の間隙１０２Ｇに進入した際（図１３の右下図参照）にピークｂを迎え、その後、なだらかに減少していく。ブラケット１の挿入部２１は、当該間隙１０２Ｇに挿入方向Ｉの前方側から数えて１つ目の摺動突起部２１Ｔが進入する際（図１３の左下図参照）には、その１つ目の摺動突起部２１Ｔが形成される側面２１ｂとは逆側の側面２１ｂの摺動突起部２１Ｔが、まだ当該間隙１０２Ｇに進入していないため、この段階では、当該間隙１０２Ｇに、挿入部２１は余裕を持って進入することができる。ところが、挿入方向Ｉの前方側から数えて２つ目の摺動突起部２１Ｔは、上記の１つ目の摺動突起部２１Ｔとは逆側の側面２１ｂに形成された突起であり、これが当該間隙１０２Ｇに進入する際には、それら１つ目と２つ目の両側の摺動突起部２１Ｔ、２１Ｔを双方とも押し潰す形で摺動抵抗が生じる。この摺動抵抗も、２つ目の摺動突起部２１Ｔが当該間隙１０２Ｇに進入する際にピークｂを迎えた後は、それら摺動突起部２１Ｔ、２１Ｔの間を挿入部２１が摺動していく引き摺り抵抗を受け続ける。 As shown in the curve B of FIG. 15, the insertion resistance generated by the second sliding protrusion 21T is a sliding protrusion alternately formed on both side surfaces 21b and 21b of the insertion portion 21 of the bracket 1 in the insertion direction I. When the second sliding protrusion 21T of the parts 21T from the front side in the insertion direction I enters the gap 102G of the case 101 (see the lower right figure of FIG. 13), the peak b is reached, and then the peak b is reached. It gradually decreases. The insertion portion 21 of the bracket 1 is the first when the first sliding protrusion 21T counted from the front side in the insertion direction I enters the gap 102G (see the lower left figure of FIG. 13). Since the sliding protrusion 21T on the side surface 21b opposite to the side surface 21b on which the sliding protrusion 21T is formed has not yet entered the gap 102G, at this stage, the insertion portion 21 is inserted into the gap 102G. You can enter with a margin. However, the second sliding protrusion 21T counted from the front side in the insertion direction I is a protrusion formed on the side surface 21b opposite to the first sliding protrusion 21T described above, and this is the protrusion. When entering the gap 102G, sliding resistance is generated by crushing both the first and second sliding protrusions 21T and 21T on both sides. As for this sliding resistance, after the peak b is reached when the second sliding protrusion 21T enters the gap 102G, the insertion portion 21 slides between the sliding protrusions 21T and 21T. Continue to receive drag resistance.

図１５の曲線Ｃに示すように、ケース１０１の弾性押付部１０２Ａが中間斜面２１ａ２から後方側上面２１ａ３に乗り上げていくときに生じる挿入抵抗は、ブラケット１の挿入部２１の上面２１ａを摺動していくケース１０１の弾性押付部１０２Ａが、中間斜面２１ａ２上で後方側上面２１ａ３に近づくほど増大して、後方側上面２１ａ３に乗り上げる際にピークｃを迎え、その後、なだらかに減少していく。なお、ここでの後方側上面２１ａ３は、挿入方向Ｉにおいて、上述の２つ目の摺動突起部２１Ｔよりも後方に位置するため、ピークｃは、ピークｂよりも後に発生している。中間斜面２１ａ２及び後方側上面２１ａ３による挿入抵抗のピークｃは、ケース１０１の弾性押付部１０２Ａに生じる第二の弾性変形が最大変位で生じた時であり、その後は、当該弾性変形状態を保ちながら弾性押付部１０２Ａが後方側上面２１ａ３上を摺動していくことによる引き摺り抵抗を受け続ける。 As shown in the curve C of FIG. 15, the insertion resistance generated when the elastic pressing portion 102A of the case 101 rides on the rear upper surface 21a3 from the intermediate slope 21a2 slides on the upper surface 21a of the insertion portion 21 of the bracket 1. The elastic pressing portion 102A of the case 101 is increased as it approaches the rear upper surface 21a3 on the intermediate slope 21a2, reaches a peak c when riding on the rear upper surface 21a3, and then gradually decreases. Since the rear upper surface 21a3 here is located behind the second sliding protrusion 21T described above in the insertion direction I, the peak c occurs after the peak b. The peak c of the insertion resistance due to the intermediate slope 21a2 and the rear upper surface 21a3 is when the second elastic deformation occurring in the elastic pressing portion 102A of the case 101 occurs at the maximum displacement, and thereafter, while maintaining the elastic deformation state. The elastic pressing portion 102A continues to receive drag resistance due to sliding on the rear upper surface 21a3.

図１５の曲線Ｄに示すように、３つ目の摺動突起部２１Ｔにより生じる挿入抵抗は、挿入方向Ｉにおいてブラケット１の挿入部２１の両側面２１ｂ、２１ｂに交互に形成された摺動突起部２１Ｔのうち、挿入方向Ｉの前方側から数えて３つ目の摺動突起部２１Ｔが、ケース１０１の間隙１０２Ｇに進入した際（図１３の右上図参照）にピークｄを迎え、その後、なだらかに減少していく。ブラケット１の挿入部２１は、当該間隙１０２Ｇに挿入方向Ｉの前方側から数えて２つ目の摺動突起部２１Ｔが進入した際（図１３の右下図参照）には、挿入方向Ｉに対し傾斜する方向にガタつく状況にあるが、３つ目の摺動突起部２１Ｔが当該間隙１０２Ｇに進入した際（図１３の右上図参照）には、３点接触によるガタつき防止状態となり、挿入姿勢が固定される。この摺動抵抗は、３つ目の摺動突起部２１Ｔが当該間隙１０２Ｇに進入する際にピークｄを迎えた後は、全摺動突起部２１Ｔが摺動することによる引き摺り抵抗を受け続ける。 As shown in the curve D of FIG. 15, the insertion resistance generated by the third sliding protrusion 21T is a sliding protrusion alternately formed on both side surfaces 21b and 21b of the insertion portion 21 of the bracket 1 in the insertion direction I. When the third sliding protrusion 21T of the parts 21T from the front side in the insertion direction I enters the gap 102G of the case 101 (see the upper right figure of FIG. 13), the peak d is reached, and then the peak d is reached. It gradually decreases. When the second sliding protrusion 21T of the bracket 1 enters the gap 102G from the front side of the insertion direction I (see the lower right figure of FIG. 13), the insertion portion 21 with respect to the insertion direction I Although it is in a state of rattling in the direction of inclination, when the third sliding protrusion 21T enters the gap 102G (see the upper right figure of FIG. 13), it is in a state of preventing rattling due to three-point contact and inserted. The posture is fixed. This sliding resistance continues to receive the drag resistance due to the sliding of all the sliding protrusions 21T after reaching the peak d when the third sliding protrusion 21T enters the gap 102G.

ブラケット１の挿入部２１をケース１０１の間隙１０２Ｇに挿入していく際の全区間における挿入抵抗（曲線Ｚ）は、これら４つの挿入抵抗（曲線Ａ、Ｂ、Ｃ、Ｄ）を合成した形にほぼ一致する。本実施例では、これら４つの挿入抵抗（曲線Ａ、Ｂ、Ｃ、Ｄ）を合成した際に、挿入方向Ｉにおける各々のピークａ、ｂ、ｃ、ｄの位置が異なるように設定されている。これにより、全体の挿入抵抗（曲線Ｚ）に、ピークが重なって挿入抵抗が激増するような区間が無いようにしてある。 The insertion resistance (curve Z) in the entire section when the insertion portion 21 of the bracket 1 is inserted into the gap 102G of the case 101 is a combination of these four insertion resistances (curves A, B, C, D). Almost match. In this embodiment, when these four insertion resistances (curves A, B, C, D) are combined, the positions of the peaks a, b, c, and d in the insertion direction I are set to be different. .. As a result, there is no section in the entire insertion resistance (curve Z) where the peaks overlap and the insertion resistance increases sharply.

なお、これらの挿入抵抗（曲線Ａ、Ｂ、Ｃ、Ｄ）のほかにも、全体の挿入抵抗（曲線Ｚ）を変化させる要素はあるが、それらは上記挿入抵抗（曲線Ａ、Ｂ、Ｃ、Ｄ）よりも影響が小さいため省略している。 In addition to these insertion resistances (curves A, B, C, D), there are elements that change the overall insertion resistance (curve Z), but they are the above-mentioned insertion resistances (curves A, B, C, D). Since the effect is smaller than D), it is omitted.

次に、組み付けられたブラケット１とケース１０１（ＥＣＵ１００）を外す方法と、それを可能にするブラケット１とケース１０１（ＥＣＵ１００）との組み付け構造１０００について、図１６及び図１７を用いて具体的に説明する。 Next, with reference to FIGS. 16 and 17, the method of removing the assembled bracket 1 and the case 101 (ECU 100) and the assembly structure 1000 of the bracket 1 and the case 101 (ECU 100) enabling the method are specifically described. explain.

なお、ブラケット１に対するケース１０１の取り外し方向は、既に述べた挿入部２１の挿入方向Ｉと同方向であるから、ここでは同じ符号を付して、取り外し方向Ｉということとする。既に述べた弾性押付部１０２Ａの受け入れ方向Ｊは、この取り外し方向Ｉとは逆方向である。また、挿入方向Ｉは、ケース１０１に対するブラケット１の組み付け方向ということもできる。 Since the removal direction of the case 101 with respect to the bracket 1 is the same as the insertion direction I of the insertion portion 21 described above, the same reference numerals are given here to refer to the removal direction I. The receiving direction J of the elastic pressing portion 102A described above is opposite to the removing direction I. Further, the insertion direction I can also be said to be the assembly direction of the bracket 1 with respect to the case 101.

組み付けられているブラケット１とケース１０１は、弾性押付部１０２Ａに対し抜け止め係止部２２が、ケース１０１の取り外し方向の後方側に回り込んで係止し、抜け止め状態となっている（図１６の第一図（最上図）参照）。この抜け止め状態を解除してブラケット１からケース１０１を取り外すために、まずは、弾性押付部１０２Ａの取り外し方向Ｉの後方側（図１６の左側）が上側で取り外し方向Ｉの前方側（図１６の右側）が下側となるよう、ケース１０１をブラケット１に対し傾斜させる（図１６の第二図及び図１７参照）。このとき、弾性押付部１０２Ａが、挿入部２１における取り外し方向Ｉの前方側（即ち、対向間２０Ｇ側）を下方に押し付ける。これにより、挿入部２１の取り外し方向Ｉの前方側が弾性的に押し下げられ、対向間２０Ｇ（第二対向間）が押し拡げられる。そして、ブラケット１に対し傾斜したケース１０１を、取り外し方向Ｉの前方側に向かってその傾斜方向Ｋ２に移動させることで、弾性押付部１０２Ａの対向間２０Ｇ（第二対向間）への進入が可能になる（図１６の第三図参照）。つまり、弾性押付部１０２Ａを抜け止め係止部２２が係止していた状態が解除される。そして、弾性押付部１０２Ａが抜け止め係止部２２を通過することにより、ケース１０１は、ブラケット１からの離脱が完了する（図１６の第四図（最下図）参照）。なお、離脱が完了した後には、押し下げられていた挿入部２１は元の位置に弾性復帰する。 The bracket 1 and the case 101 that are assembled are in a retaining state in which the retaining locking portion 22 wraps around the elastic pressing portion 102A toward the rear side in the removal direction of the case 101 and locks the case 101 (FIG. FIG. 16 (see top view). In order to release the retaining state and remove the case 101 from the bracket 1, first, the rear side (left side of FIG. 16) of the elastic pressing portion 102A is on the upper side and the front side of the removal direction I (FIG. 16). The case 101 is tilted with respect to the bracket 1 so that the right side) is on the lower side (see FIGS. 2 and 17 in FIG. 16). At this time, the elastic pressing portion 102A presses the front side (that is, the facing 20G side) of the insertion portion 21 in the removing direction I downward. As a result, the front side of the insertion portion 21 in the removal direction I is elastically pushed down, and the facing space 20G (second facing space) is pushed and expanded. Then, by moving the case 101 inclined with respect to the bracket 1 toward the front side of the removal direction I in the inclined direction K2, the elastic pressing portion 102A can enter the facing space 20G (second facing space). (See Fig. 16 in FIG. 16). That is, the state in which the elastic pressing portion 102A is locked by the retaining locking portion 22 is released. Then, when the elastic pressing portion 102A passes through the retaining locking portion 22, the case 101 is completely detached from the bracket 1 (see FIG. 4 (bottom figure) of FIG. 16). After the detachment is completed, the inserted portion 21 that has been pushed down elastically returns to the original position.

このように、ケース１０１に対し抜け止め状態に組み付けられたブラケット１は、図１７のようにケース１０１を傾斜させることで、そのケース１０１（ＥＣＵ１００）を簡単に取り外すことができる。この傾斜は、ケース１０１とブラケット１の主面対向部３との間に形成される空隙９Ｓがあることにより可能となっている。ブラケット１は、ケース１０１が組み付けられている状態において、ケース１０１を弾性押付片３２が受け入れ方向Ｊとは逆側へ押し付けており、これにより、主面対向部３と当該ケース１０１との対向間に空隙９Ｓを形成している。上記ケース１０１の傾斜は、この空隙９Ｓ（さらにいえば、この空隙９Ｓの組付け部２側から遠い側（図１７の下側））にケース１０１を進入させる形でなされている。また、ブラケット１とケース１０１とを組み付ける場合も、ケース１０１をブラケット１に対し傾斜させるが（図１２Ａの中央図）、この傾斜もこの隙間９Ｓとなる空間を利用している。 In this way, the bracket 1 assembled in a retaining state with respect to the case 101 can be easily removed from the case 101 (ECU 100) by inclining the case 101 as shown in FIG. This inclination is possible due to the presence of the gap 9S formed between the case 101 and the main surface facing portion 3 of the bracket 1. In the bracket 1 in a state where the case 101 is assembled, the elastic pressing piece 32 presses the case 101 to the side opposite to the receiving direction J, whereby the space between the main surface facing portion 3 and the case 101 facing each other A void 9S is formed in the space. The inclination of the case 101 is such that the case 101 is allowed to enter the gap 9S (more specifically, the side of the gap 9S far from the assembling portion 2 side (lower side of FIG. 17)). Further, when the bracket 1 and the case 101 are assembled, the case 101 is tilted with respect to the bracket 1 (center view of FIG. 12A), and this tilt also uses the space having the gap 9S.

なお、図中に示した傾斜方向Ｋ１、Ｋ２は、ケース１０１に対するブラケット１の組み付け・取り外しが可能となるよう、係止部４、５の対向方向２００Ｙ（以下、係止部対向方向２００Ｙという）における主面対向部３の第一側（図１７の下側）が主面対向部３に接近し、その逆の第二側（図１７の上側）が主面対向部３から離間した方向であればよく、固定的に定められた方向ではない。図１２Ａ、図１６、図１７に示す傾斜方向Ｋ１、Ｋ２は、ケース１０１に対するブラケット１の組み付け・取り外しに必要な傾斜方向の一例であり、その傾斜角度は、組付け部２の各部の弾性変形量に応じてそれらの図とは異なってもよい。また、その傾斜角度は、ケース１０１に対するブラケット１の組み付け・取り外しの途中に、その傾斜角度が変化することもありうる。傾斜方向Ｋ１、Ｋ２の双方が一致している必要もない。 The inclination directions K1 and K2 shown in the drawing are 200Y facing the locking portions 4 and 5 (hereinafter referred to as 200Y facing the locking portion) so that the bracket 1 can be assembled and removed from the case 101. In the direction in which the first side (lower side of FIG. 17) of the main surface facing portion 3 approaches the main surface facing portion 3 and the opposite second side (upper side of FIG. 17) is separated from the main surface facing portion 3. It suffices, and it is not a fixed direction. The tilting directions K1 and K2 shown in FIGS. 12A, 16 and 17 are examples of the tilting directions required for assembling and removing the bracket 1 with respect to the case 101, and the tilting angle is the elastic deformation of each part of the assembled portion 2. They may differ from those figures depending on the amount. Further, the inclination angle may change during the assembly / removal of the bracket 1 with respect to the case 101. It is not necessary that both the inclination directions K1 and K2 match.

主面対向部３は、図７及び図８に示すように、既に述べた組み付け状態（図２参照）において、ケース１０１の主面１０１ｂと対面する主面３ａを有するとともに、その主面３ａから突出するリブ状の当て止め部３１と、その主面３ａから斜め方向に延び出し、組み付けられたケース１０１の主面１０１ｂを弾性的に押し付ける弾性押付片３２と、を有する。 As shown in FIGS. 7 and 8, the main surface facing portion 3 has a main surface 3a facing the main surface 101b of the case 101 in the assembled state (see FIG. 2) already described, and from the main surface 3a. It has a rib-shaped retaining portion 31 that protrudes, and an elastic pressing piece 32 that extends obliquely from the main surface 3a and elastically presses the main surface 101b of the assembled case 101.

ところで、本実施例のブラケット本体１０は、図７及び図８に示すように、当て壁部２３、２３を有する。 By the way, as shown in FIGS. 7 and 8, the bracket main body 10 of the present embodiment has the contact wall portions 23, 23.

当て壁部２３、２３は、ブラケット１とケース１０１との組み付け状態（図２参照）において、挿入部２１に対しケース１０１の外周方向Ｓにおける両外側となる位置を、側面対向部２からケース１０１の外周側面１０１ａに向けて延び出す壁部であり、外周側面１０１ａと当接して配置される。ここでの当て壁部２３、２３は、第一の側方フレーム部２Ｂと第二の側方フレーム部２Ｃにそれぞれ形成されている。ケース１０１とブラケット１とを組み付けるための上述のような挿入構造（即ち、挿入部２１と組付け部１０２）は、ブラケット１がケース１０１に対し外周方向Ｓ（図２１参照）へと揺動する形でガタつきを生じる可能性がある。これに対し当て壁部２３、２３は、その挿入構造を、ケース１０１の外周方向Ｓの大外の位置で挟むように設けられ、ケース１０１の外周側面１０１ａと当接するから、ブラケット１の外周方向Ｓへの揺動を妨げることができる。 In the assembled state of the bracket 1 and the case 101 (see FIG. 2), the contact wall portions 23 and 23 are positioned on both outer sides of the case 101 in the outer peripheral direction S with respect to the insertion portion 21 from the side facing portions 2 to the case 101. It is a wall portion extending toward the outer peripheral side surface 101a, and is arranged in contact with the outer peripheral side surface 101a. The padding wall portions 23, 23 here are formed in the first side frame portion 2B and the second side frame portion 2C, respectively. In the above-mentioned insertion structure (that is, the insertion portion 21 and the assembly portion 102) for assembling the case 101 and the bracket 1, the bracket 1 swings in the outer peripheral direction S (see FIG. 21) with respect to the case 101. May cause rattling in shape. On the other hand, the contact wall portions 23, 23 are provided so as to sandwich the insertion structure at a position outside the outer peripheral direction S of the case 101, and come into contact with the outer peripheral side surface 101a of the case 101, so that the bracket 1 is in the outer peripheral direction. It is possible to prevent the swing to S.

ここでの当て壁部２３、２３は、側面対向部２の第一の側方フレーム部２Ｂ及び第二の側方フレーム部２Ｃから、それぞれケース１０１の外周側面１０１ａと当接する長さだけ下方に延びた壁部である。また、ここでの当て壁部２３、２３は、それら第一の側方フレーム部２Ｂと第二の側方フレーム部２Ｃとに対しそれぞれの長手方向に沿って形成されており、ケース１０１の外周側面１０１ａとの接触面積を当該長手方向においてより広く確保して、外周方向Ｓへの揺動を抑えている。また、当て壁部２３、２３は、主面対向部３と接続しているため剛性が高く、外周方向Ｓへの揺動をより安定して抑えることができる。 Here, the contact wall portions 23, 23 are lowered from the first side frame portion 2B and the second side frame portion 2C of the side facing portion 2 by the length of contact with the outer peripheral side surface 101a of the case 101, respectively. It is an extended wall part. Further, the contact wall portions 23, 23 here are formed along the longitudinal directions of the first side frame portion 2B and the second side frame portion 2C, respectively, and are formed on the outer periphery of the case 101. The contact area with the side surface 101a is secured wider in the longitudinal direction, and the swing in the outer peripheral direction S is suppressed. Further, since the contact wall portions 23 and 23 are connected to the main surface facing portion 3, the rigidity is high, and the swing in the outer peripheral direction S can be suppressed more stably.

また、当て壁部２３、２３の一方には、図７及び図８に示すように、切り欠き部２３Ｋが形成されている。 Further, as shown in FIGS. 7 and 8, a notch portion 23K is formed on one of the contact wall portions 23 and 23.

ケース１０１は、外周側面１０１ａにおける当て壁部２３の一方に対応する位置に、外向きに突出した凸部１０３（図１参照）を有しており、切り欠き部２３Ｋは、ブラケット１がケース１０１に組み付けられる際に当該凸部１０３を避けるよう、切り欠かれている。これにより、ケース１０１にブラケット１を組み付ける際には、ケース１０１の凸部１０３の位置とブラケット１の切り欠き部２３Ｋの位置を合わせなければ、当て壁部２３と凸部１０３とが干渉して組み付けられなくなる。ここでのケース１０１には、図１８に示すように、ブラケット１を組み付けるための組付け部１０２が複数個所に設けられている。具体的にいえば３つの外周側面１０１ａにそれぞれに設けられている。 The case 101 has a convex portion 103 (see FIG. 1) protruding outward at a position corresponding to one of the contact wall portions 23 on the outer peripheral side surface 101a, and the bracket 1 of the notch portion 23K is the case 101. It is cut out so as to avoid the convex portion 103 when it is assembled to the. As a result, when assembling the bracket 1 to the case 101, the contact wall portion 23 and the convex portion 103 interfere with each other unless the position of the convex portion 103 of the case 101 and the position of the notch portion 23K of the bracket 1 are aligned. It cannot be assembled. As shown in FIG. 18, the case 101 here is provided with a plurality of assembling portions 102 for assembling the bracket 1. Specifically, it is provided on each of the three outer peripheral side surfaces 101a.

なお、凸部１０３は、ここではケース１０１のカバー１１２に設けられた組付け部１１０Ｋによって形成されている。ここでのケース１０１は、図１８及び図１９に示すように、本体部１１１の外周における一面に形成された開口部１１１Ｈに対しカバー１１２が組み付けられており、そのカバー１１２には、ケース１０１の外周方向Ｓにおいてその開口部１１１Ｈに隣接する双方の外周側面１０１ａに対し外側から重なる形で組み付く組付け部１１０Ｋが形成されている。組付け部１１０Ｋは、ケース１０１の外周側面１０１ａ上に重なって位置するため、当該外周側面１０１ａ上で外向きに飛び出し、凸部１０３として現れる。 The convex portion 103 is formed here by an assembling portion 110K provided on the cover 112 of the case 101. In the case 101 here, as shown in FIGS. 18 and 19, a cover 112 is assembled to an opening 111H formed on one surface on the outer circumference of the main body 111, and the cover 112 is attached to the case 101. An assembling portion 110K is formed so as to overlap with both outer peripheral side surfaces 101a adjacent to the opening 111H in the outer peripheral direction S from the outside. Since the assembly portion 110K is positioned so as to overlap the outer peripheral side surface 101a of the case 101, it protrudes outward on the outer peripheral side surface 101a and appears as a convex portion 103.

ここで、ケース１０１をなす本体部１１１とカバー１１２との組み付け方法について説明する。 Here, a method of assembling the main body 111 forming the case 101 and the cover 112 will be described.

図２３に示すように、本体部１１１とカバー１１２とを組み付けるためには、まずは本体部１１１の開口部１１１Ｈに、カバー１１２を接近させていく。カバー１１２が開口部１１１Ｈに接近していくと、組付け部１１０Ｋは、本体部１１１において開口部１１１Ｈに隣接する外周側面１０１ａ上で、当該開口部１１１Ｈ側に形成された係止突起部１０１Ｋに当接する。この当接状態から、カバー１１２を更に押し込んでいくと、組付け部１１０Ｋが弾性変形して係止突起部１０１Ｋ上に乗り上げ、乗り越える。そして、組付け部１１０Ｋは、乗り越えた先で該係止突起部１０１Ｋと係止して抜け止め状態となる。これにより、カバー１１２が本体部１１１の開口部１１１Ｈに組み付く。 As shown in FIG. 23, in order to assemble the main body 111 and the cover 112, first, the cover 112 is brought close to the opening 111H of the main body 111. As the cover 112 approaches the opening 111H, the assembling portion 110K becomes a locking projection 101K formed on the opening 111H side on the outer peripheral side surface 101a adjacent to the opening 111H in the main body 111. Contact. When the cover 112 is further pushed in from this contact state, the assembling portion 110K elastically deforms and rides on the locking projection 101K to get over it. Then, the assembling portion 110K is locked with the locking projection portion 101K at the point where it gets over, and is in a retaining state. As a result, the cover 112 is assembled to the opening 111H of the main body 111.

このとき、組付け部１１０Ｋ上には、切り欠き部２３Ｋが重なるように位置する（図２３の最下図参照）。これにより、切り欠き部２３Ｋは、カバー１１２の開口部１１１Ｈに対する組み付き状態の解除動作を妨げるロック部として機能することとなる。即ち、開口部１１１Ｈからカバー１１２を外すためには、カバー１１２を、開口部１１１Ｈに組み付けたときとは逆向きに移動させる必要がある。ところがこの移動には、組付け部１１０Ｋと係止突起部１０１Ｋとの係止状態を解除する必要がある。解除のためには、組付け部１１０Ｋが、係止突起部１０１Ｋを組付けたときとは逆向きに乗り上げ、乗り越える弾性変形が必要となるが、組付け部１１０Ｋにおいて係止突起部１０１Ｋと係止している先端部１１１Ｋの上方には、側方フレーム部２Ｃが位置しているため、乗り上げ、乗り越えるための弾性変形ができない。その結果、ブラケット１が組み付いた状態は、組付け部１１０Ｋと係止突起部１０１Ｋとの係止状態を解除できないロック状態となる。 At this time, the notch portion 23K is located on the assembly portion 110K so as to overlap (see the bottom view of FIG. 23). As a result, the notch portion 23K functions as a lock portion that hinders the release operation of the assembled state with respect to the opening 111H of the cover 112. That is, in order to remove the cover 112 from the opening 111H, it is necessary to move the cover 112 in the opposite direction to that when the cover 112 is assembled to the opening 111H. However, for this movement, it is necessary to release the locked state between the assembling portion 110K and the locking projection portion 101K. In order to release the assembly portion 110K, it is necessary for the assembly portion 110K to ride in the opposite direction to that when the locking projection portion 101K is assembled and to overcome the elastic deformation. Since the side frame portion 2C is located above the stopped tip portion 111K, elastic deformation for riding on and over is not possible. As a result, the state in which the bracket 1 is assembled is a locked state in which the locked state of the assembled portion 110K and the locking protrusion 101K cannot be released.

ここでの組付け部１１０Ｋの先端部１１１Ｋは、図２３の最下図に示すように、切り欠き部２３Ｋの対向面との間に形成された空隙の空隙幅よりも厚みがあるため、ブラケット１が組み付いた状態において組付け部１１０Ｋと係止突起部１０１Ｋとの係止状態の解除を確実に防ぐことができる。 As shown in the lowermost figure of FIG. 23, the tip portion 111K of the assembly portion 110K here is thicker than the gap width of the gap formed between the notched portion 23K and the facing surface, so that the bracket 1 It is possible to reliably prevent the assembling portion 110K and the locking protrusion 101K from being released from the locked state in the assembled state.

次に、ブラケット１のパネル部材２００への取り付けについて説明する。 Next, attachment of the bracket 1 to the panel member 200 will be described.

ブラケット１は、図３に示すように、挿通係止部４と回り込み係止部５とを有する。他方、パネル部材２００は、挿通係止部４に対応する第一取付孔２０４と、回り込み係止部５に対応する第二取付孔２０５とを、厚み方向に貫通する貫通孔として有する。 As shown in FIG. 3, the bracket 1 has an insertion locking portion 4 and a wraparound locking portion 5. On the other hand, the panel member 200 has a first mounting hole 204 corresponding to the insertion locking portion 4 and a second mounting hole 205 corresponding to the wraparound locking portion 5 as through holes penetrating in the thickness direction.

挿通係止部４は、図４に示すように、係止部４、５の対向方向２００Ｙにおける主面対向部３の第一側（図４の下側）から、主面対向部３の後方側（即ち、ケース１０１との対面側とは逆側）へと延出し、パネル部材２００の対応する第一取付孔２０４に挿通係止される。ここでの挿通係止部４は、支柱部４２と、弾性係止片４１と、を有する。支柱部４２は、ブラケット本体１０から後方に延出し、第一取付孔２０４に挿通される。弾性係止片４１は、係止部対向方向２００Ｙにおける支柱部４２の第一側（図４の下側）を、支柱部４２の先端側から基端側へ向かって延出し、支柱部４２が第一取付孔２０４に挿通された際には、パネル部材２００をその背面２００ｂ側から正面２００ａ側に押し付ける形で係止する。また、この係止状態において、弾性係止片４１は、係止部対向方向２００Ｙにおける第二側（図４の上側）に弾性変形した状態にあり、第一取付孔２０４内でパネル部材２００を、係止部対向方向２００Ｙにおける第一側（図４の下側）に押し付けている。 As shown in FIG. 4, the insertion locking portion 4 is rearward of the main surface facing portion 3 from the first side (lower side of FIG. 4) of the main surface facing portion 3 in the facing direction 200Y of the locking portions 4 and 5. It extends to the side (that is, the side opposite to the side facing the case 101) and is inserted and locked in the corresponding first mounting hole 204 of the panel member 200. The insertion locking portion 4 here has a strut portion 42 and an elastic locking piece 41. The strut portion 42 extends rearward from the bracket main body 10 and is inserted into the first mounting hole 204. The elastic locking piece 41 extends the first side (lower side of FIG. 4) of the strut portion 42 in the direction facing the locking portion 200Y from the tip end side to the base end side of the strut portion 42, and the strut portion 42 extends. When inserted into the first mounting hole 204, the panel member 200 is locked by pressing it from the back surface 200b side to the front surface 200a side. Further, in this locked state, the elastic locking piece 41 is in a state of being elastically deformed to the second side (upper side in FIG. 4) in the locking portion facing direction 200Y, and the panel member 200 is placed in the first mounting hole 204. , Pressed against the first side (lower side in FIG. 4) in the locking portion facing direction 200Y.

ここでの弾性係止片４１は、基端側弾性部４１Ｂと、先端側弾性部４１Ａと、を有する。基端側弾性部４１Ｂは、支柱部４２とは逆側の外表面４１ｂ（以下、基端側傾斜外表面４１ｂという）が、支柱部４２の先端側から基端側に向かうに従い、支柱部４２から離れていく傾斜形状を有する（図５参照）。先端側弾性部４１Ａは、支柱部４２とは逆側の外表面４１ａ（以下、先端側傾斜外表面４１ａという）が、支柱部４２の先端側から基端側に向かうに従い、支柱部４２に近づいていく傾斜形状を有する（図５参照）。ここでの先端側弾性部４１Ａ及び基端側弾性部４１Ｂは、双方の接続部で屈曲した屈曲形状をなし、基端側傾斜外表面４１ｂと先端側傾斜外表面４１ａとが折り返すように連続している。 The elastic locking piece 41 here has a proximal end side elastic portion 41B and a distal end side elastic portion 41A. In the base end side elastic portion 41B, as the outer surface 41b on the opposite side of the support column portion 42 (hereinafter referred to as the base end side inclined outer surface 41b) moves from the tip end side to the base end side of the support end side 42, the support end side 42 It has an inclined shape that moves away from (see FIG. 5). The tip-side elastic portion 41A approaches the strut portion 42 as the outer surface 41a (hereinafter referred to as the tip-side inclined outer surface 41a) opposite to the strut portion 42 moves from the tip end side to the proximal end side of the strut portion 42. It has an inclined shape (see FIG. 5). The tip end side elastic portion 41A and the proximal end side elastic portion 41B have a bent shape bent at both connecting portions, and the proximal end side inclined outer surface 41b and the distal end side inclined outer surface 41a are continuous so as to be folded back. ing.

また、先端側弾性部４１Ａの先端部４１ＡＴ（以下、挿通先端部４１ＡＴという）は、第一取付孔２０４内を挿通して、パネル部材２００の表面２００ａ側に突出する（図４参照）。挿通先端部４１ＡＴは、支柱部４２とは逆側の外表面４１ｔ（図２５参照：以下、先端外表面４１ｔという）が、支柱部４２の先端側から基端側に向かうに従い、先端側傾斜外表面４１ａとの接続部に凹状の角部を形成する傾斜形状を有する（図５の上図参照）。 Further, the tip portion 41AT of the tip side elastic portion 41A (hereinafter referred to as the insertion tip portion 41AT) passes through the inside of the first mounting hole 204 and projects toward the surface 200a side of the panel member 200 (see FIG. 4). In the insertion tip 41AT, the outer surface 41t on the opposite side of the support 42 (see FIG. 25: hereinafter referred to as the tip outer surface 41t) is inclined toward the tip side as the outer surface 41t of the support 42 is directed from the tip side to the base end side. It has an inclined shape that forms concave corners at the connection with the surface 41a (see the upper view of FIG. 5).

回り込み係止部５は、図４に示すように、基端部５３と、中間部５１と、先端部５２と、を有する屈曲したアーム状をなし、弾性変形可能な弾性アームとして形成されている。基端部５３は、係止部対向方向２００Ｙにおける主面対向部３の第一側とは逆の第二側（図４の上側）から主面対向部３の後方側（即ち、ケース１０１との対面側とは逆側）に延出し、パネル部材２００の対応する第二取付孔２０５に挿通される。中間部５１は、第二取付孔２０５内に位置する基端部５３の先で、当該パネル部材２００の背面２００ｂ側に回り込み、当該背面２００ｂに沿って係止部対向方向２００Ｙにおける第二側（図４の上側）へと延出している。先端部５２は、当該背面２００ｂ側に回り込んだ中間部５１の先端側でパネル部材２００に対し背面２００ｂ側から接触する接触部である。ここでの先端部５２は、中間部５１の先端側でパネル部材２００側に突出し、その背面２００ｂと接触する突起部である。この先端部５２の接触の際、回り込み係止部５は、先端部５２側がパネル部材２００の背面２００ｂから離れる方向に弾性変形を生じており、その結果、先端部５２は、パネル部材２００の背面２００ｂを正面２００ａ側に押し付ける形で接触する。 As shown in FIG. 4, the wraparound locking portion 5 has a bent arm shape having a base end portion 53, an intermediate portion 51, and a tip portion 52, and is formed as an elastic arm that can be elastically deformed. .. The base end portion 53 is from the second side (upper side in FIG. 4) opposite to the first side of the main surface facing portion 3 in the locking portion facing direction 200Y to the rear side of the main surface facing portion 3 (that is, the case 101). (The side opposite to the opposite side), and is inserted into the corresponding second mounting hole 205 of the panel member 200. The intermediate portion 51 wraps around the back surface 200b side of the panel member 200 at the tip of the base end portion 53 located in the second mounting hole 205, and runs along the back surface 200b on the second side (in the locking portion facing direction 200Y). It extends to the upper side of FIG. 4). The tip portion 52 is a contact portion that comes into contact with the panel member 200 from the back surface 200b side on the front end side of the intermediate portion 51 that wraps around the back surface 200b side. The tip portion 52 here is a protrusion that protrudes toward the panel member 200 on the tip side of the intermediate portion 51 and comes into contact with the back surface 200b thereof. At the time of contact with the tip portion 52, the wraparound locking portion 5 is elastically deformed in a direction in which the tip portion 52 side is separated from the back surface 200b of the panel member 200, and as a result, the tip portion 52 is formed on the back surface of the panel member 200. The 200b is pressed against the front surface 200a to make contact.

ここで、ブラケット１のパネル部材２００への取付方法及び取付構造２０００について、図５を用いて具体的に説明する。 Here, the method of attaching the bracket 1 to the panel member 200 and the attachment structure 2000 will be specifically described with reference to FIG.

まずは図５の上図に示すように、ブラケット１の回り込み係止部５を、パネル部材２００の第二取付孔２０５に挿通する。第二取付孔２０５に挿通された回り込み係止部５は、基端部５３がパネル部材２００の第二取付孔２０５内を通過し、中間部５１がパネル部材２００の背面２００ｂ側で係止部対向方向２００Ｙにおける第二側（図５の右側）へと延出した状態となる。 First, as shown in the upper part of FIG. 5, the wraparound locking portion 5 of the bracket 1 is inserted into the second mounting hole 205 of the panel member 200. In the wraparound locking portion 5 inserted through the second mounting hole 205, the base end portion 53 passes through the inside of the second mounting hole 205 of the panel member 200, and the intermediate portion 51 is the locking portion on the back surface 200b side of the panel member 200. It is in a state of extending to the second side (right side in FIG. 5) in the opposite direction 200Y.

そしてこの状態から、ブラケット１の挿通係止部４を、パネル部材２００の第一取付孔２０４に挿入する。このとき挿通係止部４は、図５の中央図に示すように、弾性係止片４１を支柱部４２に接近させて全体をすぼませた弾性変形状態となって、第一取付孔２０４に挿通される。具体的にいえば、挿通係止部４は、第一取付孔２０４に挿入されていくときに、基端側傾斜外表面４１ｂが第一取付孔２０４の係止部対向方向２００Ｙにおける第一側（図５の中央図の左側：矢印ｐ０の方向側）の内縁２０４ｃ（図６Ｂ参照）上をスライドする形で押し付ける。この押し付けにより、弾性係止片４１は、挿入が進むほど支柱部４２側に接近していく弾性変形が生じる。また、この押し付けにより、ブラケット１の全体が係止部対向方向２００Ｙにおける第二側（図５中央図の右側：矢印Ｐ０の方向側）へと押し付けられ、回り込み係止部５の基端部５３が第二取付孔２０５の当該第二側の内縁２０５ｄに接触して、押し付けられた挿通押付状態となる。 Then, from this state, the insertion locking portion 4 of the bracket 1 is inserted into the first mounting hole 204 of the panel member 200. At this time, as shown in the central view of FIG. 5, the insertion locking portion 4 is in an elastically deformed state in which the elastic locking piece 41 is brought close to the strut portion 42 and the whole is deflated, and the first mounting hole 204 is formed. Is inserted into. Specifically, when the insertion locking portion 4 is inserted into the first mounting hole 204, the base end side inclined outer surface 41b is the first side of the first mounting hole 204 in the locking portion facing direction 200Y. (Left side of the central view of FIG. 5: the direction side of the arrow p0) is pressed on the inner edge 204c (see FIG. 6B) in a sliding manner. Due to this pressing, the elastic locking piece 41 undergoes elastic deformation that approaches the support column 42 side as the insertion progresses. Further, by this pressing, the entire bracket 1 is pressed toward the second side (right side in the central view of FIG. 5: the direction side of the arrow P0) in the locking portion facing direction 200Y, and the base end portion 53 of the wraparound locking portion 5 is pressed. Is in contact with the inner edge 205d on the second side of the second mounting hole 205, and is in a pressed insertion / pressing state.

そして、挿通係止部４の第一取付孔２０４への挿入が進んでいくと、図５の中央図に示すように、ブラケット１の回り込み係止部５の先端部５２がパネル部材２００の裏面２００ｂと接触し、なおかつブラケット１の支点部７がパネル部材２００の表面２００ａと接触した状態となる。ここから更に挿通係止部４を挿入させていくためには、挿通係止部４をより支柱部４２へと接近させる弾性変形が必要となる。このとき、第一取付孔２０４へと押し込んでいく挿通係止部４を力点、パネル部材２００の表面２００ａと接触した支点部７を支点、パネル部材２００の裏面２００ｂと接触した回り込み係止部５の先端部５２を作用点とする形で、てこの原理が働く。このため、挿通係止部４の第一取付孔２０４への押し込み力が比較的小さくても、このてこの原理によって大きな挿入力を生じさせることができるから、挿通係止部４を第一取付孔２０４へと容易に挿入することができる。 Then, as the insertion of the insertion locking portion 4 into the first mounting hole 204 progresses, as shown in the central view of FIG. 5, the tip portion 52 of the wraparound locking portion 5 of the bracket 1 becomes the back surface of the panel member 200. The fulcrum portion 7 of the bracket 1 is in contact with the surface 200a of the panel member 200 while being in contact with the 200b. In order to further insert the insertion locking portion 4 from here, elastic deformation is required to bring the insertion locking portion 4 closer to the support column portion 42. At this time, the insertion locking portion 4 pushed into the first mounting hole 204 is the point of effort, the fulcrum portion 7 in contact with the front surface 200a of the panel member 200 is the fulcrum, and the wraparound locking portion 5 in contact with the back surface 200b of the panel member 200. The principle of leverage works with the tip 52 of the lever as the point of action. Therefore, even if the pushing force of the insertion locking portion 4 into the first mounting hole 204 is relatively small, a large insertion force can be generated by the principle of leverage. Therefore, the insertion locking portion 4 is first mounted. It can be easily inserted into the hole 204.

なお、支点部７は、主面対向部３において、挿通係止部４と回り込み係止部５との間の、当該回り込み係止部５側の位置に設けられており、ここではパネル部材２００に正面２００ａ側から当接する。図５に示されている支点部７は、第二取付孔２０５上に位置し、パネル部材２００の表面２００ａに接触していないように見えるが、実際には、図４に示すように、パネル部材２００における第二取付孔２０５の周辺部に対し正面２００ａ側から接触している。また、ここでの支点部７は、図１に示すように、回り込み係止部５の基端部５３の基端側で、回り込み係止部５の幅方向両側に長く延出するリブとして形成されている。 The fulcrum portion 7 is provided at a position on the main surface facing portion 3 between the insertion locking portion 4 and the wraparound locking portion 5 on the wraparound locking portion 5 side, and here, the panel member 200. From the front 200a side. The fulcrum portion 7 shown in FIG. 5 is located on the second mounting hole 205 and does not appear to be in contact with the surface 200a of the panel member 200, but in reality, as shown in FIG. 4, the panel The member 200 is in contact with the peripheral portion of the second mounting hole 205 from the front surface 200a side. Further, as shown in FIG. 1, the fulcrum portion 7 here is formed as a rib extending long on both sides in the width direction of the wraparound locking portion 5 on the proximal end side of the base end portion 53 of the wraparound locking portion 5. Has been done.

挿通係止部４の第一取付孔２０４への挿入が、てこの原理を利用する形で更に進んでいくと、第一取付孔２０４内を挿通係止部４の基端側弾性部４１Ｂが通過し終える。そして今度は、第一取付孔２０４内を挿通係止部４の先端側弾性部４１Ａが通過していく。第一取付孔２０４内を先端側弾性部４１Ａが通過していくときには、図５の下図に示すように、先端側傾斜外表面４１ａが第一取付孔２０４の係止部対向方向２００Ｙにおける第一側の内縁２０４ｃ（図６Ｂ参照）上をスライドする形で押し付けた状態となる。先端側傾斜外表面４１ａは、その傾斜形状から、第一取付孔２０４の係止部対向方向２００Ｙにおける第一側の内縁２０４ｃを第一側（図５の下図の左側：矢印ｐ１の方向側）に押し付けつつ、パネル部材２００を裏面２００ｂ側から表面２００ａ側に向けて押し付ける。その結果、挿通係止部４は、弾性係止片４１を少しずつ弾性復帰させつつ、先端側傾斜外表面４１ａが第一取付孔２０４の係止部対向方向２００Ｙにおける第一側の内縁２０４ｃを押し付ける自身の力によって第一取付孔２０４の奥へと進入していく。その進入は、図５の下図に示すように、パネル部材２００が、ブラケット１の主面対向部３に形成された当て壁部８と当接する位置で停止する。 When the insertion of the insertion locking portion 4 into the first mounting hole 204 proceeds further by utilizing the principle of leverage, the base end side elastic portion 41B of the insertion locking portion 4 enters the inside of the first mounting hole 204. Finish passing. Then, this time, the tip-side elastic portion 41A of the insertion locking portion 4 passes through the inside of the first mounting hole 204. When the tip-side elastic portion 41A passes through the first mounting hole 204, as shown in the lower figure of FIG. 5, the tip-side inclined outer surface 41a is the first in the locking portion facing direction 200Y of the first mounting hole 204. It is in a state of being pressed by sliding on the inner edge 204c (see FIG. 6B) on the side. Due to its inclined shape, the tip-side inclined outer surface 41a has the inner edge 204c on the first side in the locking portion facing direction 200Y of the first mounting hole 204 as the first side (left side in the lower figure of FIG. 5: the direction side of arrow p1). The panel member 200 is pressed from the back surface 200b side toward the front surface 200a side while being pressed against. As a result, the insertion locking portion 4 gradually elastically restores the elastic locking piece 41, and the tip end side inclined outer surface 41a forms the inner edge 204c on the first side in the locking portion facing direction 200Y of the first mounting hole 204. It enters the depths of the first mounting hole 204 by its own force of pressing. As shown in the lower figure of FIG. 5, the approach stops at a position where the panel member 200 comes into contact with the contact wall portion 8 formed on the main surface facing portion 3 of the bracket 1.

この停止状態では、弾性係止片４１が弾性復帰途中であるから、依然として、先端側傾斜外表面４１ａが第一取付孔２０４の係止部対向方向２００Ｙにおける第一側の内縁２０４ｃを当該第一側（図５の下図の左側：矢印ｐ１の方向側）へと押し付け、かつパネル部材２００を裏面２００ｂ側から正面２００ａ側へと押し付けた状態に保たれる。つまり、この状態の挿通係止部４は、弾性係止片４１の先端側傾斜外表面４１ａがパネル部材２００の裏面２００ｂ側から係止（接触）した挿通係止状態にある。そして、このとき回り込み係止部５も、パネル部材２００の裏面２００ｂ側に回り込んで係止状態となっている。このように、挿通係止部４と回り込み係止部５との双方の係止状態が成立した状態が、ブラケット１がパネル部材２００に対し取り付けられた取付状態である。 In this stopped state, since the elastic locking piece 41 is in the process of elastic recovery, the tip-side inclined outer surface 41a still makes the first side inner edge 204c of the first mounting hole 204 in the locking portion facing direction 200Y. The panel member 200 is pressed toward the side (left side in the lower figure of FIG. 5: the direction side of the arrow p1), and the panel member 200 is kept pressed from the back surface 200b side to the front surface 200a side. That is, the insertion locking portion 4 in this state is in an insertion locking state in which the tip-side inclined outer surface 41a of the elastic locking piece 41 is locked (contacted) from the back surface 200b side of the panel member 200. At this time, the wraparound locking portion 5 also wraps around to the back surface 200b side of the panel member 200 and is in a locked state. In this way, the state in which both the insertion locking portion 4 and the wraparound locking portion 5 are locked is the mounting state in which the bracket 1 is attached to the panel member 200.

この取付状態において、弾性復帰途中の弾性係止片４１は、既に述べたように、パネル部材２００の係止部対向方向２００Ｙにおける第一側（図５の下図の左側）において、当て壁部８側（即ち、主面対向部３側）へと弾性的に常に押し付けた状態に保たれている。よって、ブラケット１は、取り付けられたパネル部材２００の当該第一側において、パネル部材２００との接近離間方向に生じるガタつきが抑制された状態にある。 In this mounting state, as described above, the elastic locking piece 41 in the process of elastic recovery is the contact wall portion 8 on the first side (left side in the lower figure of FIG. 5) of the panel member 200 in the locking portion facing direction 200Y. It is kept in a state of being elastically pressed against the side (that is, the side facing the main surface 3) at all times. Therefore, the bracket 1 is in a state in which rattling that occurs in the approaching / separating direction with the panel member 200 is suppressed on the first side of the attached panel member 200.

また、この取付状態において、回り込み係止部５は、パネル部材２００の係止部対向方向２００Ｙにおける第二側（図５の下図の右側）において、裏面２００ｂ側へと回り込んで先端部５２側が当該パネル部材２００から離間する側へと弾性変形した弾性変形状態にあり、当該先端部５２がパネル部材２００を支点部７側（即ち、主面対向部３側）へと弾性的に常に押し付けた状態に保たれている。よって、ブラケット１は、取り付けられたパネル部材２００の係止部対向方向２００Ｙにおける第二側において、当該パネル部材２００との接近離間方向に生じるガタつきが抑制された状態にある。 Further, in this mounted state, the wraparound locking portion 5 wraps around to the back surface 200b side on the second side (right side in the lower figure of FIG. 5) in the locking portion facing direction 200Y of the panel member 200, and the tip portion 52 side is It is in an elastically deformed state in which it is elastically deformed to a side separated from the panel member 200, and the tip portion 52 elastically always presses the panel member 200 to the fulcrum portion 7 side (that is, the main surface facing portion 3 side). It is kept in a state. Therefore, the bracket 1 is in a state in which rattling that occurs in the approaching / separating direction with the panel member 200 is suppressed on the second side of the attached panel member 200 in the locking portion facing direction 200Y.

また、この取付状態において、弾性復帰途中にある弾性係止片４１は、パネル部材２００の係止部対向方向２００Ｙにおける第一側において、第一取付孔２０４の内縁２０４ｃを、当該第一側（図５の下図のｐ１方向側）へと弾性的に常に押し付けた状態に保たれている。また、この押し付けにより、ブラケット１は、その全体が係止部対向方向２００Ｙにおける第二側（図５の下図のｐ２方向側）にも常に押し付けられた状態に保たれている。よって、ブラケット１は、取り付けられたパネル部材２００に対し係止部対向方向２００Ｙの第一側や第二側へと生じるガタつきが抑制された状態にある。 Further, in this mounting state, the elastic locking piece 41, which is in the process of elastic recovery, has the inner edge 204c of the first mounting hole 204 on the first side (the first side ( It is kept in a state of being elastically and always pressed toward the p1 direction side in the lower figure of FIG. Further, by this pressing, the entire bracket 1 is always kept pressed against the second side (the p2 direction side in the lower figure of FIG. 5) in the locking portion facing direction 200Y. Therefore, the bracket 1 is in a state in which rattling that occurs on the first side and the second side in the locking portion facing direction 200Y with respect to the attached panel member 200 is suppressed.

また、この取付状態において、各係止部４、５は、対応する取付孔２０４、２０５に挿通され、その内縁２０４ｃ、２０５ｄに当接して係止状態となるだけでなく、それら取付孔２０４、２０５内における所定位置に位置保持されている。以下、この位置保持について説明する。 Further, in this mounting state, the locking portions 4 and 5 are inserted into the corresponding mounting holes 204 and 205, and not only come into contact with the inner edges 204c and 205d to be locked, but also the mounting holes 204, The position is held in a predetermined position in 205. Hereinafter, this position holding will be described.

挿通係止部４及び第一取付孔２０４の内縁には、図６Ａに示すように、その挿通係止状態において、係止部対向方向２００Ｙの第一側（図６Ａの上側）に向けて常に押し付けられている弾性係止片４１（先端側弾性部４１Ａ）を、第一取付孔２０４の係止部対向方向２００Ｙにおける第一側の内縁２０４ｃ（図６Ｂ参照）に接する形で定められた第一所定位置に止める位置保持部が設けられている。ここでは、図６Ｂに示すように、支柱部４２に設けられた取付孔内縁押付部４８、４９と、第一取付孔２０４の内縁２０４ａ、２０４ｂとが位置保持部として機能している。 As shown in FIG. 6A, the inner edges of the insertion locking portion 4 and the first mounting hole 204 are always facing the first side (upper side of FIG. 6A) in the locking portion facing direction 200Y in the insertion locking state. The pressed elastic locking piece 41 (tip-side elastic portion 41A) is defined so as to be in contact with the first-side inner edge 204c (see FIG. 6B) in the locking portion facing direction 200Y of the first mounting hole 204. (I) A position holding portion for stopping at a predetermined position is provided. Here, as shown in FIG. 6B, the mounting hole inner edge pressing portions 48 and 49 provided in the support column portion 42 and the inner edges 204a and 204b of the first mounting hole 204 function as position holding portions.

ここでの弾性係止片４１は、第一取付孔２０４内において、係止部対向方向２００Ｙ（図６Ａの上下方向）のガタつきを自らの押し付けによって抑えているが、弾性係止片４１には、その係止部対向方向２００Ｙに直交する直交方向２００Ｘ（図６Ａの左右方向）におけるガタつきを防ぐ手段が無いと、弾性係止片４１だけでは挿通係止部４を第一所定位置に止めることはできない。 The elastic locking piece 41 here suppresses rattling in the locking portion facing direction 200Y (vertical direction in FIG. 6A) in the first mounting hole 204 by its own pressing, but the elastic locking piece 41 If there is no means for preventing rattling in the orthogonal direction 200X (horizontal direction in FIG. 6A) orthogonal to the locking portion facing direction 200Y, the elastic locking piece 41 alone puts the insertion locking portion 4 in the first predetermined position. I can't stop it.

これに対し取付孔内縁押付部４８は、挿通係止部４が第一取付孔２０４に挿通係止された状態において、上記直交方向２００Ｘにおける第一側（図６Ｂの左側）で第一取付孔２０４の内縁２０４ａと当接する当接部である。他方、取付孔内縁押付部４９は、第一取付孔２０４に挿通係止された状態において、その逆の第二側（図５Ａの右側）で第一取付孔２０４の内縁２０４ｂを押し付けるよう弾性変形可能な弾性片である。これにより、挿通係止部４は、第一取付孔２０４に挿通係止された状態において、第一取付孔２０４の内縁２０４ａ、２０４ｂを取付孔内縁押付部４８、４９が上記直交方向２００Ｘに常に押し付けた状態となるため、上記直交方向２００Ｘ（図６Ｂの左右方向）におけるガタつきを防いで第一所定位置に止まることができる。 On the other hand, the mounting hole inner edge pressing portion 48 has a first mounting hole on the first side (left side in FIG. 6B) in the orthogonal direction 200X in a state where the insertion locking portion 4 is inserted and locked in the first mounting hole 204. It is a contact portion that comes into contact with the inner edge 204a of 204. On the other hand, the mounting hole inner edge pressing portion 49 is elastically deformed so as to press the inner edge 204b of the first mounting hole 204 on the opposite second side (right side in FIG. 5A) in a state of being inserted and locked in the first mounting hole 204. It is a possible elastic piece. As a result, in the state where the insertion locking portion 4 is inserted and locked in the first mounting hole 204, the inner edges 204a and 204b of the first mounting hole 204 are always pressed with the inner edges 48 and 49 of the mounting holes in the orthogonal direction 200X. Since it is in the pressed state, it is possible to prevent rattling in the orthogonal direction 200X (left-right direction in FIG. 6B) and stop at the first predetermined position.

具体的にいえば、第一取付孔２０４は、四角形状の貫通孔、さらにいえば第二取付孔２０５よりも係止部対向方向２００Ｙに長い長方形状の貫通孔として形成されており、係止部対向方向２００Ｙとその直交方向２００Ｘとのそれぞれに対し直交する４つの直線状の内縁２０４ａ、２０４ｂ、２０４ｃ、２０４ｄに取り囲まれている。取付孔内縁押付部４８は、上記直交方向２００Ｘに所定幅を有する支柱部４２の、当該直交方向２００Ｘにおける第一側（図６Ｂの左側）の端部である。取付孔内縁押付部４８の先端面は、第一取付孔２０４における上記直交方向２００Ｘの第一側に位置する直線状の内縁２０４ａに対し直線状に面接触する接触領域を有している。他方、取付孔内縁押付部４９は、上記直交方向２００Ｘに所定幅を有する支柱部４２の第二側（図６Ｂの右側）の端部から延出して、上記直交方向２００Ｘの第一側に弾性変形可能とされた弾性片である。このため、取付孔内縁押付部４９は、挿通係止部４が第一取付孔２０４に挿通係止された状態において、上記直交方向２００Ｘの第一側に弾性変形する形で第一取付孔２０４内に収容され、第一取付孔２０４における直線状の内縁２０４ｂを常に押し付けている。 Specifically, the first mounting hole 204 is formed as a rectangular through hole, more specifically, a rectangular through hole 200Y longer than the second mounting hole 205 in the direction facing the locking portion, and is locked. It is surrounded by four linear inner edges 204a, 204b, 204c, and 204d that are orthogonal to each of the portion facing direction 200Y and the orthogonal direction 200X. The mounting hole inner edge pressing portion 48 is an end portion of the support column portion 42 having a predetermined width in the orthogonal direction 200X on the first side (left side in FIG. 6B) in the orthogonal direction 200X. The tip surface of the mounting hole inner edge pressing portion 48 has a contact region that linearly contacts the linear inner edge 204a located on the first side of the first mounting hole 204 in the orthogonal direction 200X. On the other hand, the mounting hole inner edge pressing portion 49 extends from the end on the second side (right side in FIG. 6B) of the strut portion 42 having a predetermined width in the orthogonal direction 200X, and is elastic on the first side in the orthogonal direction 200X. It is an elastic piece that can be deformed. Therefore, the mounting hole inner edge pressing portion 49 is elastically deformed to the first side in the orthogonal direction 200X in a state where the insertion locking portion 4 is inserted and locked in the first mounting hole 204. It is housed inside and constantly presses the linear inner edge 204b in the first mounting hole 204.

ここでの取付孔内縁押付部４９は、係止部対向方向２００Ｙ側（ここでは図６Ｂの上側）かつ上記直交方向２００Ｘの第二側（図６Ｂの右側）となる斜め方向４９ｙ（図６Ｂ参照）に延出する形で形成されている。挿通係止部４の挿通係止状態（図５の下図参照）において、取付孔内縁押付部４９は、上記直交方向２００Ｘの第一側へと弾性的に押し曲げられた弾性変形状態に保たれ、第一取付孔２０４の内縁２０４ｂを常に押し付けた状態とされる。これにより、挿通係止部４は、上記直交方向２００Ｘおいて第一取付孔２０４の内縁２０４ａ、２０４ｂを常に押し付けた状態となって、上記直交方向２００Ｘにおけるガタつきの防止と位置保持とを実現している。 Here, the mounting hole inner edge pressing portion 49 is in an oblique direction 49y (see FIG. 6B) on the side facing the locking portion 200Y (here, the upper side in FIG. 6B) and the second side in the orthogonal direction 200X (right side in FIG. 6B). ) Is formed. In the insertion-locking state of the insertion-locking portion 4 (see the lower diagram of FIG. 5), the mounting hole inner edge pressing portion 49 is maintained in an elastically deformed state of being elastically pushed and bent toward the first side in the orthogonal direction 200X. , The inner edge 204b of the first mounting hole 204 is always pressed. As a result, the insertion locking portion 4 is in a state of constantly pressing the inner edges 204a and 204b of the first mounting hole 204 in the orthogonal direction 200X, and realizes prevention of rattling and position holding in the orthogonal direction 200X. ing.

一方、回り込み係止部５及び第二取付孔２０５の内縁にも、図６Ａに示すように、その回り込み係止状態において、係止部対向方向２００Ｙの第二側（図６Ａの下側）に向けて常に押し付けられている基端部５３を、第二取付孔２０５の当該第二側の内縁２０５ｄ上に定められた第二所定位置に止める位置保持部が設けられている。ここでは、図６Ｃに示すように、回り込み係止部５の基端部に設けられた取付孔内縁押付部５９、５９と、第二取付孔２０５の内縁２０５ａ、２０５ｂとが、位置保持部として機能している。 On the other hand, as shown in FIG. 6A, the inner edges of the wraparound locking portion 5 and the second mounting hole 205 are also on the second side (lower side of FIG. 6A) in the locking portion facing direction 200Y in the wraparound locking state. A position holding portion is provided to stop the base end portion 53, which is constantly pressed toward the subject, at a second predetermined position defined on the inner edge 205d of the second side of the second mounting hole 205. Here, as shown in FIG. 6C, the mounting hole inner edge pressing portions 59 and 59 provided at the base end portion of the wraparound locking portion 5 and the inner edges 205a and 205b of the second mounting hole 205 serve as position holding portions. It is functioning.

ここでの基端部５３は、逆側の第一取付孔２０４内における弾性係止片４１の係止部対向方向２００Ｙの第一側への押し付けによって、第二取付孔２０５の係止部対向方向２００Ｙにおける第二側の内縁２０５ｄへと押し付けられており、係止部対向方向２００Ｙ（図６Ａの上下方向）のガタつきが抑えられている。ところが、基端部５３には、その係止部対向方向２００Ｙに直交する直交方向２００Ｘ（図６Ａの左右方向）におけるガタつきを防ぐ手段が無いと、弾性係止片４１だけでは挿通係止部４を第一所定位置に止めることはできない。 The base end portion 53 here is pressed against the first side in the locking portion facing direction 200Y of the elastic locking piece 41 in the first mounting hole 204 on the opposite side, so that the second mounting hole 205 faces the locking portion. It is pressed against the inner edge 205d on the second side in the direction 200Y, and rattling in the locking portion facing direction 200Y (vertical direction in FIG. 6A) is suppressed. However, if the base end portion 53 does not have a means for preventing rattling in the orthogonal direction 200X (horizontal direction in FIG. 6A) orthogonal to the locking portion facing direction 200Y, the elastic locking piece 41 alone is used as the insertion locking portion. 4 cannot be stopped at the first predetermined position.

これに対し、回り込み係止部５は、直交方向２００Ｘのガタつきを防いで第二所定位置に止まるために、取付孔内縁押付部５９、５９を基端部５３に有した形状となっている。取付孔内縁押付部５９、５９は、回り込み係止部５が第二取付孔２０５に係止された回り込み係止状態において、それぞれが上記直交方向２００Ｘにおける第一側及びその逆の第二側（図６Ｃの左側及び右側）で第二取付孔２０５の内縁２０５ａ、２０５ｂを押し付けるよう弾性変形可能な弾性片である。これにより、回り込み係止部５は、第二取付孔２０５に挿通係止された状態において、第二取付孔２０５の内縁２０５ａ、２０５ｂを常に押し付けた状態となるため、上記直交方向２００Ｘ（図６Ｃの左右方向）におけるガタつきを防いで第二所定位置に止まることができる。 On the other hand, the wraparound locking portion 5 has a shape in which the mounting hole inner edge pressing portions 59 and 59 are provided at the base end portion 53 in order to prevent rattling in the orthogonal direction 200X and stop at the second predetermined position. .. The mounting hole inner edge pressing portions 59 and 59 are in a wraparound locking state in which the wraparound locking portion 5 is locked in the second mounting hole 205, respectively, on the first side in the orthogonal direction 200X and the second side vice versa ( It is an elastic piece that can be elastically deformed so as to press the inner edges 205a and 205b of the second mounting hole 205 on the left and right sides of FIG. 6C). As a result, the wraparound locking portion 5 is in a state of constantly pressing the inner edges 205a and 205b of the second mounting hole 205 in a state of being inserted and locked in the second mounting hole 205, so that the orthogonal direction 200X (FIG. 6C). It is possible to prevent rattling in the (left-right direction) and stop at the second predetermined position.

具体的にいえば、第二取付孔２０５は、四角形状の貫通孔、さらにいえば第一取付孔２０４よりも上記直交方向２００Ｘに長い長方形状の貫通孔として形成されており、係止部対向方向２００Ｙとその直交方向２００Ｘとのそれぞれに対し直交する４つの直線状の内縁２０５ａ、２０５ｂ、２０５ｃ、２０５ｄに取り囲まれている。取付孔内縁押付部５９、５９は、それぞれが上記直交方向２００Ｘに所定幅を有する基端部５３の両側（図６Ｃの左右両側）の端部から外向きに延出して、基端部５３の先端側（即ち、中間部５１側）からの押し付けによって上記直交方向２００Ｘの内向きに弾性変形可能とされた弾性片である。このため取付孔内縁押付部５９、５９は、回り込み係止部５が第二取付孔２０５に係止された回り込み係止状態において、それぞれが上記直交方向２００Ｘの内向きに弾性変形する形で第二取付孔２０５内に収容され、第二取付孔２０５における直線状の内縁２０５ａ、２０５ｂを常に押し付けている。 Specifically, the second mounting hole 205 is formed as a rectangular through hole, more specifically, a rectangular through hole that is longer than the first mounting hole 204 in the orthogonal direction 200X, and faces the locking portion. It is surrounded by four linear inner edges 205a, 205b, 205c, 205d that are orthogonal to each of the direction 200Y and its orthogonal direction 200X. The mounting hole inner edge pressing portions 59 and 59 extend outward from the ends of both sides (left and right sides in FIG. 6C) of the base end portion 53 having a predetermined width in the orthogonal direction 200X, respectively, to extend the base end portion 53. It is an elastic piece that can be elastically deformed inward in the orthogonal direction 200X by pressing from the tip side (that is, the intermediate portion 51 side). Therefore, the wraparound locking portions 59 and 59 are elastically deformed inward in the orthogonal direction 200X in the wraparound locking state in which the wraparound locking portion 5 is locked in the second mounting hole 205. (2) It is housed in the mounting hole 205 and constantly presses the linear inner edges 205a and 205b in the second mounting hole 205.

ここでの取付孔内縁押付部５９、５９は、基端部５３から上記直交方向２００Ｘの外向きに延出する形で形成されている。回り込み係止部５の回り込み係止状態（図５の下図参照）において、取付孔内縁押付部５９、５９は、それぞれが上記直交方向２００Ｘの内向きに弾性的に押し曲げられた弾性変形状態に保たれ、それぞれが第二取付孔２０５の内縁２０５ａ、２０５ｂを常に押し付けた状態とされる。これにより、回り込み係止部５は、上記直交方向２００Ｘおいて第二取付孔２０５の内縁２０５ａ、２０５ｂを常に押し付けた状態となって、上記直交方向２００Ｘにおけるガタつきの防止と位置保持とを実現している。 The mounting hole inner edge pressing portions 59 and 59 are formed so as to extend outward in the orthogonal direction 200X from the base end portion 53. In the wraparound locking state of the wraparound locking portion 5 (see the lower figure of FIG. 5), the mounting hole inner edge pressing portions 59 and 59 are each elastically deformed inward in the orthogonal direction 200X. It is maintained and is in a state where the inner edges 205a and 205b of the second mounting hole 205 are constantly pressed against each other. As a result, the wraparound locking portion 5 is in a state where the inner edges 205a and 205b of the second mounting hole 205 are constantly pressed in the orthogonal direction 200X, and the rattling is prevented and the position is maintained in the orthogonal direction 200X. ing.

なお、各取付孔内縁押付部４９、５９、５９は、主面対向部３との間に空隙を挟んでおり、主面対向部３とは非接続に形成されている。これにより、各取付孔内縁押付部４９、５９、５９は、弾性変形を生じやすくなっている。 The inner edge pressing portions 49, 59, 59 of the mounting holes are formed so as to have a gap between them and the main surface facing portion 3 so as not to be connected to the main surface facing portion 3. As a result, the inner edge pressing portions 49, 59, 59 of each mounting hole are liable to be elastically deformed.

また、ここでの挿通係止部４及び回り込み係止部５は、回り込み係止部５（基端部５３）の方が挿通係止部４（弾性係止片４１、支柱部４２）よりも上記直交方向２００Ｘの幅が広い。また、第一取付孔２０４及び第二取付孔２０５についても、第二取付孔２０５の方が第一取付孔２０４よりも、上記直交方向２００Ｘの孔幅が広く形成されている。このため本実施例では、係止部対向方向２００Ｙの第一側（図６Ａの上側）において、第一取付孔２０４に対し挿通係止部４が当該第一側に向かって押し付ける第一側押付領域４Ｓに対し、係止部対向方向２００Ｙの第二側（図６Ａの下側）において、第二取付孔２０５に対し回り込み係止部５が当該第二側向かって押し付ける第二側押付領域５Ｓの方が、押し付け方向（即ち、係止部対向方向２００Ｙ）に直交する方向２００Ｘに長い領域として設けられている。つまり、回り込み係止部５は、上記直交方向２００Ｘに長いため、第二取付孔２０５の係止部対向方向２００Ｙにおける第二側の内縁２０５ｄに対し、上記直交方向２００Ｘの両端側の２か所において接触しているとみることができる一方、挿通係止部４は、上記直交方向２００Ｘに短いから、第一取付孔２０４の係止部対向方向２００Ｙにおける第一側の内縁２０４ｃに対し、１か所で接触しているとみることができる。このため、ブラケット１は、パネル部材２００の異なる３か所において、互いに離間する側へと押し付けられた形で組み付けられているといえる。このような３点での支持は、係止部対向方向２００Ｙへのガタを防止するだけでなく、それら３点を通過する平面上でそれら３点のうち１点を中心に回転する方向へのガタつきも抑えることができる。また、このような３点支持は、三脚等のように、２点や１点での支持に比べて安定し、かつ４点以上での支持より効率的であるという利点もある。 Further, as for the insertion locking portion 4 and the wraparound locking portion 5, the wraparound locking portion 5 (base end portion 53) is larger than the insertion locking portion 4 (elastic locking piece 41, strut portion 42). The width of the orthogonal direction 200X is wide. Further, with respect to the first mounting hole 204 and the second mounting hole 205, the second mounting hole 205 is formed to have a wider hole width in the orthogonal direction 200X than the first mounting hole 204. Therefore, in this embodiment, on the first side (upper side of FIG. 6A) of the locking portion facing direction 200Y, the insertion locking portion 4 presses against the first mounting hole 204 toward the first side. On the second side (lower side of FIG. 6A) of the locking portion facing direction 200Y with respect to the region 4S, the second side pressing region 5S that wraps around the second mounting hole 205 and the locking portion 5 presses toward the second side. Is provided as a longer region in the direction 200X orthogonal to the pressing direction (that is, the locking portion facing direction 200Y). That is, since the wraparound locking portion 5 is long in the orthogonal direction 200X, there are two locations on both ends of the orthogonal direction 200X with respect to the inner edge 205d on the second side in the locking portion facing direction 200Y of the second mounting hole 205. On the other hand, since the insertion locking portion 4 is short in the orthogonal direction 200X, the insertion locking portion 4 is 1 with respect to the inner edge 204c on the first side in the locking portion facing direction 200Y of the first mounting hole 204. It can be seen that they are in contact at some point. Therefore, it can be said that the bracket 1 is assembled in a form of being pressed to a side separated from each other at three different positions of the panel member 200. Such support at three points not only prevents backlash in the locking portion facing direction 200Y, but also in a direction of rotating around one of the three points on a plane passing through the three points. It can also suppress rattling. Further, such a three-point support has an advantage that it is more stable than a support at two points or one point and more efficient than a support at four points or more like a tripod or the like.

このような形でブラケット１がパネル部材２００に取り付けられることにより、挿通係止部４や回り込み係止部５は、車両の走行振動等でブラケット１に上記直交方向２００Ｘへの力が働いたとしても、弾性係止片４１によって係止部対向方向２００Ｙに常に押し付けられる力と、取付孔内縁押付部４９、５９、５９によって上記直交方向２００Ｘに常に押し付けられる力とを利用して、第一取付孔２０４や第二取付孔２０５内に定められた第一所定位置や第二所定位置に止まることができる。仮にそれら所定位置からずれたとしても、それら係止部対向方向２００Ｙと上記直交方向２００Ｘとに作用する押し付け力が、挿通係止部４や回り込み係止部５を押し戻すから、容易に元の所定位置に戻ることができる。 By attaching the bracket 1 to the panel member 200 in this way, it is assumed that the insertion locking portion 4 and the wraparound locking portion 5 exert a force on the bracket 1 in the orthogonal direction 200X due to the running vibration of the vehicle or the like. Also, the first mounting is performed by utilizing the force that is always pressed in the locking portion facing direction 200Y by the elastic locking piece 41 and the force that is always pressed in the orthogonal direction 200X by the mounting hole inner edge pressing portions 49, 59, 59. It can stop at the first predetermined position or the second predetermined position defined in the hole 204 or the second mounting hole 205. Even if they deviate from their predetermined positions, the pressing force acting on the locking portion facing direction 200Y and the orthogonal direction 200X pushes back the insertion locking portion 4 and the wraparound locking portion 5, so that the original predetermined position can be easily obtained. You can return to the position.

次に、ブラケット１のパネル部材２００からの取り外し方法及びそれを可能にする取り付け構造２０００について、図２４及び図２５を用いて具体的に説明する。 Next, a method of removing the bracket 1 from the panel member 200 and a mounting structure 2000 that enables the bracket 1 will be specifically described with reference to FIGS. 24 and 25.

ブラケット１をパネル部材２００から取り外すためには、ブラケット１とパネル部材２００との間の空隙９Ｓに治具９Ｄを進入させ、当該治具９Ｄによって弾性係止片４１（挿通先端部４１Ａ）を支柱部４２側に押し込み、第一取付孔２０４との挿通係止状態を解除することにより可能となる。 In order to remove the bracket 1 from the panel member 200, the jig 9D is inserted into the gap 9S between the bracket 1 and the panel member 200, and the elastic locking piece 41 (insertion tip portion 41A) is supported by the jig 9D. This is possible by pushing it toward the portion 42 and releasing the insertion / locking state with the first mounting hole 204.

ここでは、治具９Ｄによる弾性係止片４１（挿通先端部４１Ａ）の押し込みが容易になるよう、ブラケット１の主面対向部３に切り欠き部３９が設けられている（図３参照）。具体的にいえば、切り欠き部３９は、ブラケット１の主面対向部３を、係止部対向方向２００Ｙの第一側の端部から挿通係止部４の弾性係止片４１の直下までを切り欠いた形で形成されている。ブラケット１は、パネル部材２００に取り付けられた状態において、切り欠き部３９の当該第一側の開放側から治具９Ｄ（ここでは棒状治具）を進入させることにより、第一取付孔２０４を通ってブラケット１側に突出する弾性係止片４１の先端部４１ＡＴ（以下、挿通先端部４１ＡＴという）を支柱部４２側に弾性変形させることが可能であり、当該弾性変形によって挿通係止部４の第一取付孔２０４への挿通係止状態が解除され、前記パネル部材から取り外すことができる。 Here, a notch 39 is provided in the main surface facing portion 3 of the bracket 1 so that the elastic locking piece 41 (insertion tip portion 41A) can be easily pushed by the jig 9D (see FIG. 3). Specifically, the notch 39 extends the main surface facing portion 3 of the bracket 1 from the first end in the locking portion facing direction 200Y to directly below the elastic locking piece 41 of the insertion locking portion 4. It is formed in the shape of a notch. The bracket 1 passes through the first mounting hole 204 by allowing the jig 9D (here, a rod-shaped jig) to enter from the open side of the first side of the notch 39 in a state of being mounted on the panel member 200. The tip portion 41AT of the elastic locking piece 41 protruding toward the bracket 1 side (hereinafter referred to as the insertion tip portion 41AT) can be elastically deformed toward the support column portion 42, and the insertion locking portion 4 can be elastically deformed by the elastic deformation. The insertion / locking state to the first mounting hole 204 is released, and the panel member can be removed.

具体的にいえば、まずは図２４の上図に示すように、マイナスドライバーのような棒状治具９Ｄを、パネル部材２００の表面２００ａに沿って（例えば表面２００ａ上を滑らすように）切り欠き部３９の開放側から奥へと進入させていく。そうすると、弾性係止片４１の挿通先端部４１Ａに接触する。ただし、接触しても棒状治具９Ｄの進入を止めることはできず、弾性係止片４１を支柱部４２側へと弾性変形させる形で棒状治具９Ｄの進入は続く。この進入は、図２４の中央図に示すように、弾性変形した弾性係止片４１（挿通先端部４１Ａ）が支柱部４２に当接する位置まで続く。 Specifically, first, as shown in the upper part of FIG. 24, a rod-shaped jig 9D such as a flat-blade screwdriver is inserted along the surface 200a of the panel member 200 (for example, so as to slide on the surface 200a). It is made to enter from the open side of 39 to the back. Then, the elastic locking piece 41 comes into contact with the insertion tip 41A. However, even if they come into contact with each other, the entry of the rod-shaped jig 9D cannot be stopped, and the entry of the rod-shaped jig 9D continues in the form of elastically deforming the elastic locking piece 41 toward the support column 42 side. As shown in the central view of FIG. 24, this approach continues until the elastically deformed elastic locking piece 41 (insertion tip portion 41A) abuts on the strut portion 42.

弾性係止片４１（挿通先端部４１Ａ）が支柱部４２に当接すると、第一取付孔２０４との挿通係止状態が解除され、弾性係止片４１を含む挿通係止部４全体が、第一取付孔２０４から離脱可能になる。したがって、図２４の中央図のような状態で、棒状治具９Ｄの先端側をそのままにして、棒状治具９Ｄの基端側をパネル部材２００から離脱する方向へ持ち上げることにより、ブラケット１あるいはケース１０１が押し上げられて、挿通係止部４が第一取付孔２０４から離脱する。挿通係止部４が離脱したならば、残りは回り込み係止部５を第二取付孔２０５から取り外せば、ブラケット１はパネル部材２００から取り外すことができる。 When the elastic locking piece 41 (insertion tip 41A) comes into contact with the support column 42, the insertion locking state with the first mounting hole 204 is released, and the entire insertion locking portion 4 including the elastic locking piece 41 is released. It becomes possible to separate from the first mounting hole 204. Therefore, the bracket 1 or the case is formed by lifting the base end side of the rod-shaped jig 9D in the direction of detaching from the panel member 200 while leaving the tip end side of the rod-shaped jig 9D as it is in the state as shown in the central view of FIG. 101 is pushed up, and the insertion locking portion 4 is separated from the first mounting hole 204. When the insertion locking portion 4 is disengaged, the remaining wraparound locking portion 5 can be removed from the panel member 200 by removing the wraparound locking portion 5 from the second mounting hole 205.

ただし、ここでの棒状治具９Ｄは、マイナスドライバーであり、その先端部９ＤＴが先細り形状をなしている。このため、図２４の中央図の状態から、ブラケット１がパネル部材２００から取り外されていく手順は、以下のようになる。 However, the rod-shaped jig 9D here is a flat-blade screwdriver, and its tip portion 9DT has a tapered shape. Therefore, the procedure for removing the bracket 1 from the panel member 200 from the state shown in the center of FIG. 24 is as follows.

即ち、図２５に示すように、弾性係止片４１（挿通先端部４１Ａ）を支柱部４２に当接させた棒状治具９Ｄは、その進入方向のさらに奥へと進入する。具体的にいえば、弾性係止片４１の挿通先端部４１Ａに接触した棒状治具９Ｄは、挿通先端部４１Ａの先端外表面４１ｔ上をスライドする形で、進入方向のさらに奥へと進入していく。このとき、挿通先端部４１Ａの先端外表面４１ｔは、棒状治具９Ｄの進入方向においてブラケット１側へと上る傾斜面として形成されているため、棒状治具９Ｄは、挿通先端部４１Ａの先端外表面４１ｔ上をスライドしていく形で矢印Ｄ１の方向へと移動していく。この移動によって棒状治具９Ｄは、ブラケット１側に変位していき、その結果、ブラケット１の切り欠き部３９の底部３９Ｄと当接して、これを矢印Ｄ２方向へと押し上げていくことになる。つまり、パネル部材２００の表面２００ａに沿ってブラケット１の切り欠き部３９内に進入させた棒状治具９Ｄは、そのまま奥へと進入させていくだけで、挿通係止部４の係止状態を解除するだけでなく、ブラケット１に接近していく方向に自然に変位して、ブラケット１をパネル部材２００から離脱させる側へと持ち上げていく。このため、ブラケット１が持ち上がっていくときに、棒状治具９Ｄの先端側をそのまますくい上げるように矢印Ｄ２方向へと動かせば、ブラケット１はパネル部材２００から簡単に取り外すことができる。なお、図２４及び図２５については、ケース１０１の内部構造に関する図示を省略している。 That is, as shown in FIG. 25, the rod-shaped jig 9D in which the elastic locking piece 41 (insertion tip portion 41A) is brought into contact with the support column portion 42 enters further in the approaching direction. Specifically, the rod-shaped jig 9D in contact with the insertion tip 41A of the elastic locking piece 41 slides on the outer surface 41t of the tip of the insertion tip 41A and enters further in the approach direction. To go. At this time, since the outer surface 41t of the tip of the insertion tip 41A is formed as an inclined surface that rises toward the bracket 1 in the approach direction of the rod jig 9D, the rod jig 9D is outside the tip of the insertion tip 41A. It slides on the surface 41t and moves in the direction of arrow D1. By this movement, the rod-shaped jig 9D is displaced toward the bracket 1, and as a result, it comes into contact with the bottom 39D of the notch 39 of the bracket 1 and pushes it up in the direction of the arrow D2. That is, the rod-shaped jig 9D that has entered the notch 39 of the bracket 1 along the surface 200a of the panel member 200 is simply pushed into the back to release the locked state of the insertion locking portion 4. Not only that, it naturally displaces in the direction of approaching the bracket 1 and lifts the bracket 1 to the side where it is separated from the panel member 200. Therefore, when the bracket 1 is lifted, the bracket 1 can be easily removed from the panel member 200 by moving the tip side of the rod-shaped jig 9D in the direction of the arrow D2 so as to scoop up the tip side as it is. In FIGS. 24 and 25, the illustration of the internal structure of the case 101 is omitted.

以上、本発明の第一実施例を説明したが、これはあくまでも例示にすぎず、本発明はこれに限定されるものではなく、特許請求の範囲の趣旨を逸脱しない限りにおいて、当業者の知識に基づいて、追加及び省略等の種々の変更が可能である。 The first embodiment of the present invention has been described above, but this is merely an example, and the present invention is not limited thereto, and knowledge of those skilled in the art as long as it does not deviate from the scope of claims. Various changes such as addition and omission can be made based on the above.

以下、上記実施例とは異なる別の実施例や変形例について説明する。なお、上記実施例と共通の機能を有する部位には同一符号を付して詳細な説明を省略する。また、上記実施例と下記例とは、技術的な矛盾を生じない範囲において適宜組み合わせて実施できる。 Hereinafter, another embodiment and modification different from the above embodiment will be described. The parts having the same functions as those in the above embodiment are designated by the same reference numerals, and detailed description thereof will be omitted. Further, the above-mentioned example and the following example can be appropriately combined and carried out within a range that does not cause a technical contradiction.

上記実施例のブラケット１は、１つの挿通係止部４と、それよりも幅広となる１つの回り込み係止部５とによって、パネル部材２００に対し取り付けられていたが、挿通係止部４と回り込み係止部５の数は、これとは異なっていてもよい。 The bracket 1 of the above embodiment is attached to the panel member 200 by one insertion locking portion 4 and one wraparound locking portion 5 wider than the insertion locking portion 4. The number of wraparound locking portions 5 may be different from this.

例えば１つの挿通係止部４と、２つの回り込み係止部５によって、パネル部材２００に対し取り付けられていてもよい。以下、図２６及び図２７Ａ〜図２７Ｃに示す第二実施例について説明する。 For example, it may be attached to the panel member 200 by one insertion locking portion 4 and two wraparound locking portions 5. Hereinafter, the second embodiment shown in FIGS. 26 and 27A to 27C will be described.

第二実施例においては、パネル部材２００に第一取付孔２０４が１つ設けられ、その第一取付孔２０４に対し１つの挿通係止部が挿通係止される。第一取付孔２０４の係止部対向方向２００Ｙにおける第一側の内縁２０４ｃは、図２７Ｂに示すように、当該第一側に向けて押し付けられた弾性係止片４１（先端側弾性部４１Ａ）を、当該内縁２０４ｃ上の第一所定位置に止める位置保持形状を有する。ここでの内縁２０４ｃは、弾性係止片４１が係止部対向方向２００Ｙにおける第一側に押し付けられた際、当該弾性係止片４１によるブラケット１の押付方向ｐ１に直交する直交方向２００Ｘの両側で対向し、かつその対向幅が当該第一側ほど狭幅とされた対向部２０４Ｃ、２０４Ｃを有する。弾性係止片４１がそれら対向部２０４Ｃ、２０４Ｃに両側から挟まれる位置が、挿通係止部４の第一所定位置と定められている。 In the second embodiment, the panel member 200 is provided with one first mounting hole 204, and one insertion locking portion is inserted and locked to the first mounting hole 204. As shown in FIG. 27B, the inner edge 204c on the first side of the first mounting hole 204 in the direction facing the locking portion 200Y is an elastic locking piece 41 (tip side elastic portion 41A) pressed toward the first side. Has a position-holding shape for stopping at the first predetermined position on the inner edge 204c. The inner edge 204c here is both sides of the orthogonal direction 200X orthogonal to the pressing direction p1 of the bracket 1 by the elastic locking piece 41 when the elastic locking piece 41 is pressed against the first side in the locking portion facing direction 200Y. The facing portions 204C and 204C are opposed to each other and the facing width is narrower toward the first side. The position where the elastic locking piece 41 is sandwiched between the opposing portions 204C and 204C from both sides is defined as the first predetermined position of the insertion locking portion 4.

具体的にいえば、ここでの第一取付孔２０４の内縁２０４ｃは、円弧状に形成され、弾性係止片４１における第一取付孔２０４の内縁２０４ｃとの接触面４１ｕ（弾性係止片４１の係止部対向方向２００Ｙにおける第一側（図２７Ｂの上側）の面）が、内縁２０４ｃの円弧よりも径の小さい円弧状に形成されている。この場合、円弧状の内縁２０４ｃの係止部対向方向２００Ｙにおける最も第一側の位置が第一所定位置、その第一所定位置に対し上記直交方向２００Ｘにおける第一側の円弧区間が一方の対向部２０４Ｃ、その逆の第二側の円弧区間が他方の対向部２０４Ｃである。弾性係止片４１は、第一所定位置に位置した状態において、それら対向部２０４Ｃ、２０４Ｃの双方に同時に接触しており、この同時接触状態が上述した対向部２０４Ｃ、２０４Ｃに両側から挟まれた状態である。 Specifically, the inner edge 204c of the first mounting hole 204 here is formed in an arc shape, and the contact surface 41u (elastic locking piece 41) of the elastic locking piece 41 with the inner edge 204c of the first mounting hole 204. The first side (upper side in FIG. 27B) surface in the locking portion facing direction 200Y is formed in an arc shape having a diameter smaller than the arc of the inner edge 204c. In this case, the position on the first side of the arc-shaped inner edge 204c in the locking portion facing direction 200Y is the first predetermined position, and the arc section on the first side in the orthogonal direction 200X faces one of the first predetermined positions. The arc section on the second side of the portion 204C and vice versa is the other opposing portion 204C. The elastic locking piece 41 is in contact with both of the facing portions 204C and 204C at the same time when it is located at the first predetermined position, and this simultaneous contact state is sandwiched between the facing portions 204C and 204C described above from both sides. It is in a state.

また、第二実施例においては、パネル部材２００に第二取付孔２０５が２つ設けられ、それら第二取付孔２０５、２０５に対しそれぞれ１つの挿通されて係止される。第二取付孔２０５の係止部対向方向２００Ｙにおける第二側の内縁２０５ｄは、図２７Ｃに示すように、当該第二側に向けて押し付けられた回り込み係止部５の基端部５３を、当該内縁２０５ｄ上の第二所定位置に止める位置保持形状を有する。ここでの内縁２０５ｄは、回り込み係止部５の基端部５３が係止部対向方向２００Ｙにおける第二側に押し付けられた際、当該基端部５３によるブラケット１の押付方向ｐ２に直交する上記直交方向２００Ｘにおける両側で対向し、かつその対向幅が係止部対向方向２００Ｙにおける第二側ほど狭幅とされた対向部２０５Ｃ、２０５Ｃを有しており、当該基端部５３がそれら対向部２０５Ｃ、２０５Ｃに両側から挟まれる位置が第二所定位置と定められている。 Further, in the second embodiment, the panel member 200 is provided with two second mounting holes 205, and one is inserted into and locked to each of the second mounting holes 205 and 205. As shown in FIG. 27C, the inner edge 205d on the second side of the second mounting hole 205 in the direction facing the locking portion 200Y has a base end portion 53 of the wraparound locking portion 5 pressed toward the second side. It has a position-holding shape that stops at a second predetermined position on the inner edge 205d. The inner edge 205d here is orthogonal to the pressing direction p2 of the bracket 1 by the base end portion 53 when the base end portion 53 of the wraparound locking portion 5 is pressed against the second side in the locking portion facing direction 200Y. It has facing portions 205C and 205C that face each other on both sides in the orthogonal direction 200X and whose facing width is narrower toward the second side in the locking portion facing direction 200Y, and the base end portion 53 is the facing portion. The position sandwiched between the 205C and 205C from both sides is defined as the second predetermined position.

具体的にいえば、ここでの第二取付孔２０５の内縁２０５ｄが円弧状に形成され、更に回り込み係止部５の基端部５３における第二取付孔２０５の内縁２０５ｄとの接触面５３ｄ（基端部５３の係止部対向方向２００Ｙにおける第二側（図２７Ｃの下側）の面）が、内縁２０５ｄの円弧よりも径の小さい円弧状に形成されている。この場合、円弧状の内縁２０５ｄの係止部対向方向２００Ｙにおける最も第二側の位置が第二所定位置、その第二所定位置に対し上記直交方向２００Ｘにおける第二側の円弧区間が一方の対向部２０５Ｃ、その逆の第二側の円弧区間が他方の対向部２０５Ｃ、２０５Ｃである。回り込み係止部５の基端部５３は、第二所定位置に位置した状態において、それら対向部２０５Ｃ、２０５Ｃの双方に同時に接触しており、この同時接触状態が、対向部２０５Ｃ、２０５Ｃに両側から挟まれた状態である。 Specifically, the inner edge 205d of the second mounting hole 205 is formed in an arc shape, and the contact surface 53d of the base end portion 53 of the wraparound locking portion 5 with the inner edge 205d of the second mounting hole 205 ( The second side (lower side of FIG. 27C) of the base end portion 53 in the locking portion facing direction 200Y is formed in an arc shape having a diameter smaller than the arc of the inner edge 205d. In this case, the position on the second side of the arcuate inner edge 205d in the locking portion facing direction 200Y is the second predetermined position, and the arc section on the second side in the orthogonal direction 200X faces one of the second predetermined positions. The arc section on the second side of the portion 205C and vice versa is the other opposing portions 205C and 205C. The base end portion 53 of the wraparound locking portion 5 is in contact with both of the facing portions 205C and 205C at the same time in a state of being positioned at the second predetermined position, and this simultaneous contact state is on both sides of the facing portions 205C and 205C. It is in a state of being sandwiched from.

このように、第二実施例では、挿通係止部４による第一取付孔２０４の押し付け位置が１か所、回り込み係止部５の基端部５３による第二取付孔２０５の押し付け位置が２か所あり、これら合わせて３か所において係止部対向方向２００Ｙへの押し付けがなされている。このような三点での支持は、２点や１点での支持に比べて安定し、かつ４点以上での支持より効率的であるから、第二実施例のブラケット１も、パネル部材２００に対しガタつきなく安定して組み付けることができる。なお、挿通係止部４と回り込み係止部５の数を逆にして、第一取付孔２０４の押し付け位置を２か所、第二取付孔２０５の押し付け位置を１か所とすることもできる。 As described above, in the second embodiment, the pressing position of the first mounting hole 204 by the insertion locking portion 4 is one place, and the pressing position of the second mounting hole 205 by the base end portion 53 of the wraparound locking portion 5 is 2. There are places, and a total of three places are pressed against the locking portion in the opposite direction 200Y. Since such support at three points is more stable than support at two points or one point and more efficient than support at four points or more, the bracket 1 of the second embodiment is also the panel member 200. It can be assembled stably without rattling. It is also possible to reverse the number of the insertion locking portion 4 and the wraparound locking portion 5 so that the first mounting hole 204 is pressed at two positions and the second mounting hole 205 is pressed at one position. ..

また、第二実施例のように、挿通係止部４と回り込み係止部５とが合計で３つ設けられる構成に関しては、以下のような構成とすることもできる。 Further, as in the second embodiment, the configuration in which the insertion locking portion 4 and the wraparound locking portion 5 are provided in total of three can be configured as follows.

即ち、第二実施例においては、１つの挿通係止部４から２つの回り込み係止部５までの距離が双方とも同じであったが、例えば図２８に示すように、それら３つの係止部のうち１つの係止部から他の係止部までの距離として定められる３つの係止位置間距離ｄ１、ｄ２、ｄ３を、それぞれ異なる長さとすることができる。このように３つの係止部でパネル部材に対し組み付けられる場合、１つの係止部から他の２つの係止部までの距離が一致していると、パネル部材と平行な平面上において、１つの係止部から等距離にある２つの係止部が、その１つの係止部を中心とする同一の円弧軌跡上を揺動する形で、ブラケットがガタつく可能性がある。しかしながら、上記のように１つの係止部から他の２つの係止部までの距離を異なるようにすることで、２つの係止部の揺動軌跡が一致しなくなるため、揺動を妨げ、ガタつきを抑制することができる。 That is, in the second embodiment, the distances from one insertion locking portion 4 to the two wraparound locking portions 5 were the same for both, but as shown in FIG. 28, for example, these three locking portions. The distances d1, d2, and d3 between the three locking positions, which are defined as the distances from one locking portion to the other locking portion, can have different lengths. When assembled to the panel member with three locking portions in this way, if the distances from one locking portion to the other two locking portions are the same, one on a plane parallel to the panel member. The bracket may rattle in a form in which two locking portions equidistant from the one locking portion swing on the same arc trajectory centered on the one locking portion. However, by making the distances from one locking portion to the other two locking portions different as described above, the swing trajectories of the two locking portions do not match, which hinders swinging. It is possible to suppress rattling.

図２８に示す第三実施例では、挿通係止部４の係止位置から一方の回り込み係止部５の係止位置までの距離ｄ１と、挿通係止部４の係止位置から他方の回り込み係止部５の係止位置までの距離ｄ２と、２つの回り込み係止部５の係止位置の間の距離ｄ３と、が異なっている。 In the third embodiment shown in FIG. 28, the distance d1 from the locking position of the insertion locking portion 4 to the locking position of one wraparound locking portion 5 and the wraparound from the locking position of the insertion locking portion 4 to the other. The distance d2 to the locking position of the locking portion 5 and the distance d3 between the locking positions of the two wraparound locking portions 5 are different.

なお、上述の係止位置間距離ｄ１、ｄ２、ｄ３は、図２８に示すように、ブラケット１とパネル部材２００の取付状態において、パネル部材２００に設けられた取付孔２０４、２０５とそこに挿通されたブラケット１の係止部４、５とが係止（接触）している係止位置間の距離（接触位置間あるいは押し付け位置間の距離ともいえる）のことをいうものとする。 As shown in FIG. 28, the above-mentioned distances d1, d2, and d3 between the locking positions are inserted into the mounting holes 204 and 205 provided in the panel member 200 and the mounting holes 204 and 205 in the mounting state of the bracket 1 and the panel member 200. It refers to the distance between the locking positions where the locking portions 4 and 5 of the bracket 1 are locked (contacted) (it can also be said to be the distance between the contact positions or the pressing positions).

また、第一実施例のように、１つの挿通係止部４、１つの回り込み係止部５と、を有するが、第一実施例とは異なるような構成としてもよい。例えば図２９に示す第四実施例のような構成とすることができる。 Further, as in the first embodiment, one insertion locking portion 4 and one wraparound locking portion 5 are provided, but the configuration may be different from that in the first embodiment. For example, the configuration can be as shown in the fourth embodiment shown in FIG. 29.

第二及び第三実施例においては、１つの取付孔２０４、２０５に対し１つの係止部４、５が挿通されているが、１つの取付孔２０４、２０５に対し２つの係止部４、５が挿通されてもよい。例えば図２９に示す第四実施例のように、１つの第二取付孔２０５に対し２つの回り込み係止部５、５が挿通されるように構成することができる。この構成では、第一取付孔２０４及び挿通係止部４の構成は第二及び第三実施例と同様であるが、第二取付孔２０５及び回り込み係止部５の構成が第二及び第三実施例とは異なっている。 In the second and third embodiments, one locking portion 4 and 5 is inserted through one mounting hole 204 and 205, but two locking portions 4 and 5 are inserted through one mounting hole 204 and 205. 5 may be inserted. For example, as in the fourth embodiment shown in FIG. 29, two wraparound locking portions 5 and 5 can be inserted through one second mounting hole 205. In this configuration, the configurations of the first mounting hole 204 and the insertion locking portion 4 are the same as those of the second and third embodiments, but the configurations of the second mounting hole 205 and the wraparound locking portion 5 are the second and third. It is different from the embodiment.

即ち、第四実施例において、第二取付孔２０５の内縁２０５ｄは、対向部２０５Ｄ、２０５Ｄを有する。対向部２０５Ｄ、２０５Ｄのうちの一方は、２つの回り込み係止部５、５の基端部５３、５３が係止部対向方向２００Ｙにおける第二側（図２９の下側）に押し付けられた際にそれら基端部５３、５３によるブラケット１の押付方向ｐ２に直交する直交方向２００Ｘの両側で対向し、その対向幅が係止部対向方向２００Ｙにおける第二側ほど狭幅とされている。また、この構成において、第二取付孔２０５の内縁２０５ｄは、対向部２０５Ｄ、２０５Ｄの係止部対向方向２００Ｙにおける第二側（図２９の下側）に移動規制部２０５Ｅを有する。移動規制部２０５Ｅは、２つの回り込み係止部５、５の基端部５３、５３が当該第二側に押し付けられた際に、対向部２０５Ｄ、２０５Ｄに沿って当該第二側に押し付けられる基端部５３、５３に対し当接して、当該押し付けによる移動を妨げる壁部として形成されている。 That is, in the fourth embodiment, the inner edge 205d of the second mounting hole 205 has facing portions 205D and 205D. One of the facing portions 205D and 205D is when the base end portions 53 and 53 of the two wraparound locking portions 5 and 5 are pressed against the second side (lower side in FIG. 29) in the locking portion facing direction 200Y. The base end portions 53, 53 face each other on both sides in the orthogonal direction 200X orthogonal to the pressing direction p2 of the bracket 1, and the opposite width is narrower toward the second side in the locking portion facing direction 200Y. Further, in this configuration, the inner edge 205d of the second mounting hole 205 has a movement restricting portion 205E on the second side (lower side in FIG. 29) of the facing portions 205D and 205D in the locking portion facing direction 200Y. The movement restricting unit 205E is a group that is pressed against the second side along the opposing portions 205D and 205D when the base end portions 53 and 53 of the two wraparound locking portions 5 and 5 are pressed against the second side. It is formed as a wall portion that comes into contact with the ends 53 and 53 and prevents movement due to the pressing.

次に、第五実施例について、図３０Ａ〜図３０Ｃと、図３１Ａ及び図３１Ｂとを用いて説明する。 Next, the fifth embodiment will be described with reference to FIGS. 30A to 30C, and FIGS. 31A and 31B.

第五実施例では、図３０Ａ及び図３０Ｂに示すように、パネル部材２００に設けられる第一取付孔２０４の形状が、四方の角部が他の実施例よりも径大の円弧形状をなして形成されている。さらにいえば、第一取付孔２０４は、係止部対向方向２００Ｙの第一側と第二側との双方の内縁２０４ｃ、２０４ｄが円弧状で、係止部対向方向２００Ｙの直交方向２００Ｘの両側の内縁２０４ａ、２０４ｂが直線状をなす略楕円状をなす。 In the fifth embodiment, as shown in FIGS. 30A and 30B, the shape of the first mounting hole 204 provided in the panel member 200 is an arc shape having four corners having a diameter larger than that of the other embodiments. It is formed. Further, the first mounting hole 204 has arcuate inner edges 204c and 204d on both the first side and the second side in the locking portion facing direction 200Y, and both sides in the orthogonal direction 200X in the locking portion facing direction 200Y. The inner edges 204a and 204b of the above form a substantially elliptical shape.

挿通係止部４は、他の実施例と同様に形成されている。支柱部４２の直交方向２００Ｘの両側の端部には、第一取付孔内縁押付部４８、４９が形成されており、そのうちの一方（ここでは図３０Ｂの右側）の第一取付孔内縁押付部４９は、係止部対向方向２００Ｙの第一側（図３０Ｂの上側）に延び出し、上記直交方向２００Ｘの内側（第一取付孔内縁押付部４８側：図３０Ｂの左側）に弾性変形可能な弾性片４９である。 The insertion locking portion 4 is formed in the same manner as in other embodiments. First mounting hole inner edge pressing portions 48 and 49 are formed at both ends of the support column 42 in the orthogonal direction 200X, and one of them (here, the right side in FIG. 30B) is formed with the first mounting hole inner edge pressing portion. 49 extends to the first side (upper side of FIG. 30B) in the locking portion facing direction 200Y, and can be elastically deformed to the inside of the orthogonal direction 200X (first mounting hole inner edge pressing portion 48 side: left side of FIG. 30B). It is an elastic piece 49.

第一取付孔２０４は、挿通係止部４の挿通係止状態において当該弾性片４９（の先端部４９Ａ）に押し付けられる内縁２０４ｒが係止部対向方向２００Ｙの第一側（図３０Ｂの上側）に向かうほど直交方向２００Ｘの内側（図３０Ｂの左側）に位置する湾曲形状を有する。この内縁２０４ｒは、第一取付孔２０４における係止部対向方向２００Ｙの第一側の内縁２０４ｃの一端側であり、押し付けてくる弾性片４９の延出先端側（先端部４９Ａ）を自身の湾曲形状に沿うよう弾性変形させる。これにより、第一取付孔２０４は、弾性変形したその弾性片４９によって、係止部対向方向２００Ｙの第一側（図３０Ｂの上側）と直交方向２００Ｘの外側（図３０Ｂの右側）との双方に押し付けられた状態となる。 The first mounting hole 204 has an inner edge 204r pressed against the elastic piece 49 (the tip end portion 49A) of the insertion locking portion 4 in the insertion locking state on the first side (upper side of FIG. 30B) in the locking portion facing direction 200Y. It has a curved shape located inside 200X in the orthogonal direction (left side in FIG. 30B) toward the direction of. The inner edge 204r is one end side of the first side inner edge 204c in the locking portion facing direction 200Y in the first mounting hole 204, and the extension tip side (tip portion 49A) of the elastic piece 49 to be pressed is curved by itself. Elastically deform to follow the shape. As a result, the first mounting hole 204 is formed by the elastically deformed elastic piece 49, both on the first side in the locking portion facing direction 200Y (upper side in FIG. 30B) and on the outer side in the orthogonal direction 200X (right side in FIG. 30B). It will be in a state of being pressed against.

また、挿通係止部４の弾性係止片４１は、図３０Ｂに示すように、挿通係止部４の挿通係止状態において、円弧状をなす第一取付孔２０４の内縁２０４ｃに対し、第一側への押し付け方向ｐ１（２００Ｙ）に直交する直交方向２００Ｘにおいて、その中央を挟んだ一方側とその逆の他方側との２位置４１ａ０、４１ｂ０で押し付ける形状をなす。他方、回り込み係止部５の基端部５３は、図３０Ｃに示すように、第二取付孔２０５の内縁に対し直交方向２００Ｘの両側で接触する形状を有する。即ち、基端部５３は、上記直交方向の両端側で外向きに突出する第二取付孔内縁押付部５９、５９を有しており、それら第二取付孔内縁押付部５９、５９が、第二取付孔２０５における直交方向２００Ｘの両側の内縁２０５ａ、２０５ｂに対し接触する形状をなす。そして、図３０Ａに示すように、回り込み係止部５の基端部５３が第二取付孔２０５の内縁２０５ａ、２０５ｂに接触する接触位置５３ａ０、５３ｂ０は、挿通係止部４の弾性係止片４１が第一取付孔２０４の内縁２０４ｃを押し付ける２位置４１ａ０、４１ｂ０よりも、上記直交方向２００Ｘにおいて外側に位置している。 Further, as shown in FIG. 30B, the elastic locking piece 41 of the insertion locking portion 4 has a position with respect to the inner edge 204c of the first mounting hole 204 having an arc shape in the insertion locking state of the insertion locking portion 4. In the orthogonal direction 200X orthogonal to the pressing direction p1 (200Y) to one side, the shape is formed by pressing at two positions 41a0 and 41b0 of one side sandwiching the center thereof and the other side opposite to the center. On the other hand, as shown in FIG. 30C, the base end portion 53 of the wraparound locking portion 5 has a shape of contacting the inner edge of the second mounting hole 205 on both sides in the orthogonal direction 200X. That is, the base end portion 53 has the second mounting hole inner edge pressing portions 59, 59 protruding outward on both end sides in the orthogonal direction, and the second mounting hole inner edge pressing portions 59, 59 are the second. (Ii) The mounting hole 205 has a shape that contacts the inner edges 205a and 205b on both sides in the orthogonal direction 200X. Then, as shown in FIG. 30A, the contact positions 53a0 and 53b0 at which the base end portion 53 of the wraparound locking portion 5 contacts the inner edges 205a and 205b of the second mounting hole 205 are elastic locking pieces of the insertion locking portion 4. 41 is located outside the two positions 41a0 and 41b0 that press the inner edge 204c of the first mounting hole 204 in the orthogonal direction 200X.

ここで、ブラケット１に対し上記直交方向２００Ｘの振動が生じた場合を考える。なお、図３１Ａは、パネル部材２００に取り付けられた状態のブラケット１の裏面３ｂ側（即ち、主面３ａの裏側）を示した図であり、パネル部材２００の第一取付孔２０４と第二取付孔２０５が二点鎖線で示されている。 Here, consider the case where the vibration of the bracket 1 in the orthogonal direction 200X occurs. Note that FIG. 31A is a view showing the back surface 3b side (that is, the back side of the main surface 3a) of the bracket 1 attached to the panel member 200, and the first attachment hole 204 and the second attachment of the panel member 200. Hole 205 is indicated by an alternate long and short dash line.

上記振動が生じることにより、挿通係止部４は、図３１Ａの左右へと変位する。図３１Ｂに示すように、挿通係止部４が図３１Ａの左側に変位する力Ｆを受けた場合、挿通係止部４には、図３１Ａの左側の第二取付孔内縁押付部５９が第二取付孔２０５の内縁２０５ｂと接触する接触位置５３ｂを中心に回転させる左向きの力が作用する。この力は、上記２位置４１ａ０、４１ｂ０においてそれぞれ矢印４１ａＲ、４１ｂＲの方向に作用する力である。なお、符号４１ａｒ、４１ｂｒは、回転中心となる接触位置５３ｂからそれら２位置４１ａ０、４１ｂ０に向かう径方向を示している。挿通係止部４は、上記２位置４１ａ０、４１ｂ０で第一取付孔２０４の円弧状の内縁２０４ｃを押し付けており、その押し付ける力によって当該円弧状の内縁２０４ｃ上をスライドする形で、図中左側へと変位する。ただし、上記２位置４１ａ０、４１ｂ０において作用する力のうち、一方の位置４１ｂ０で作用する力は、第一取付孔２０４の円弧状の内縁２０４ｃを、その接線方向４１ｂ１に向かう成分を有しつつも、その法線方向４１ｂ２に向かう成分も比較的大きく有している。このため、挿通係止部４１の押し付け位置４１ｂ０は、接線方向４１ｂ１の力を受けて当該円弧状の内縁２０４ｃに沿ってスライドするだけではなく、当該円弧状の内縁２０４ｃを押し付ける方向４１ｂ２にも力を作用させる。つまり、振動によってブラケット１が受ける力Ｆは、その一部が円弧状の内縁２０４ｃを押し付ける力として当該内縁２０４ｃに受け止められることで、円弧状の内縁２０４ｃに沿った方向に作用する力が減じられるから、当該内縁２０４ｃに沿ったスライド変位、即ちガタつきを抑えることができる。これは、挿通係止部４が図３１Ａの右側に変位する場合も同様である（この場合、上記線方向４１ｂ１に接線方向４１ａ１が対応し、上記法線方向４１ｂ２に法線方向４１ａ２が対応する）。このように、第五実施例では、第一取付孔２０４の円弧状の内縁２０４ｃに対する弾性係止部４１の２点接触により、ブラケット１のガタつきを抑制できる。 Due to the vibration, the insertion locking portion 4 is displaced to the left and right in FIG. 31A. As shown in FIG. 31B, when the insertion locking portion 4 receives a force F that displaces to the left side of FIG. 31A, the insertion locking portion 4 has a second mounting hole inner edge pressing portion 59 on the left side of FIG. 31A. (Ii) A leftward force that rotates around the contact position 53b that comes into contact with the inner edge 205b of the mounting hole 205 acts. This force is a force acting in the directions of arrows 41aR and 41bR at the two positions 41a0 and 41b0, respectively. Reference numerals 41ar and 41br indicate radial directions from the contact position 53b, which is the center of rotation, toward those two positions 41a0 and 41b0. The insertion locking portion 4 presses the arc-shaped inner edge 204c of the first mounting hole 204 at the above two positions 41a0 and 41b0, and slides on the arc-shaped inner edge 204c by the pressing force on the left side in the drawing. Displace to. However, of the forces acting at the two positions 41a0 and 41b0, the force acting at one position 41b0 has a component of the arcuate inner edge 204c of the first mounting hole 204 toward the tangential direction 41b1. , The component toward the normal direction 41b2 is also relatively large. Therefore, the pressing position 41b0 of the insertion locking portion 41 not only slides along the arc-shaped inner edge 204c by receiving the force in the tangential direction 41b1, but also exerts a force in the direction 41b2 for pressing the arc-shaped inner edge 204c. To act. That is, the force F received by the bracket 1 due to the vibration is partially received by the inner edge 204c as a force for pressing the arc-shaped inner edge 204c, so that the force acting in the direction along the arc-shaped inner edge 204c is reduced. Therefore, the slide displacement along the inner edge 204c, that is, the rattling can be suppressed. This also applies when the insertion locking portion 4 is displaced to the right side of FIG. 31A (in this case, the tangential direction 41a1 corresponds to the line direction 41b1 and the normal direction 41a2 corresponds to the normal direction 41b2. ). As described above, in the fifth embodiment, the rattling of the bracket 1 can be suppressed by the two-point contact of the elastic locking portion 41 with respect to the arcuate inner edge 204c of the first mounting hole 204.
