Abstract

PROBLEM TO BE SOLVED: To provide a band clip for a wire harness, improved in holding force.SOLUTION: A band clip for a wire harness includes: lower leg portions 18 and 19 projected from inner ends of locking surfaces of locking claws 16-3 and 17-3 in a lowermost stage in lower portions of blade portions 14 and 15 on a side of a wire harness attachment portion to face an inner peripheral surface of an attachment hole of a vehicle body; triangular inclined projections 20 and 21 provided so as to expand downward on outer surfaces of the lower leg portions; and wedge-like cuts 22 and 23 provided so as to be directed from the inner surfaces of the lower leg portions toward upper end sides of the inclined projections. When the blade portions and locking claws 16 and 17 are pressed excessively to fall down inward, the inclined outer surfaces of the inclined projections become vertical surfaces, and when the inclined projections are only pressed inward, the cuts are closed and the inclined outer surfaces of the inclined projections become vertical, so that the inclined outer surfaces of the inclined projections which become the vertical surfaces can be brought into contact with the inner peripheral surface of the attachment hole of the vehicle body.

Description

本発明はワイヤハーネス用のバンドクリップに関し、詳しくは、自動車等に配索するワイヤハーネスに取り付けられて車体の取付穴にクリップを挿入係止するバンドクリップにおいて、クリップの係止部を押し込み過ぎても車体パネルとの係止を確保できるようにするものである。   The present invention relates to a band clip for a wire harness, and more specifically, in a band clip that is attached to a wire harness routed in an automobile or the like and inserts and locks the clip into a mounting hole of a vehicle body, and the clip is pushed too far. Also, it is possible to ensure locking with the vehicle body panel.

従来、この種のワイヤハーネス用のバンドクリップは種々提案されている。例えば、特開２０１０−１５１１７４号公報で本出願人が提案している図９に示すバンドクリップ１００は、締結バンド１０２を本体１０３から突設したワイヤハーネス取付部１０１と、該ワイヤハーネス取付部１０１と一体成形したクリップ１０５とからなる。該クリップ１０５は本体１０３の外面に突設した皿部１１０から左右一対の支柱部１１１Ａ、１１１Ｂを突設し、該一対の支柱部１１１Ａと１１１Ｂの突出端を連結する架橋部１１２に、短手方向（幅方向）Ｙの両側で且つ長手方向Ｘで左右に位相させて一対の羽根部１１３Ａ、１１３Ｂを基部側の皿部１１０に向けて折り返し状に突設し、各羽根部１１３Ａ、１１３Ｂの外面にそれぞれ複数段（３段）の係止爪１１４Ａ、１１４Ｂを設けている。また、羽根部１１３Ａと１１３Ｂの隣接する内側端同士を連結する中央連結部１１６を設けている。   Conventionally, various band clips for this type of wire harness have been proposed. For example, a band clip 100 shown in FIG. 9 proposed by the present applicant in Japanese Patent Application Laid-Open No. 2010-151174 includes a wire harness attachment portion 101 in which a fastening band 102 is provided protruding from a main body 103, and the wire harness attachment portion 101. And the clip 105 integrally formed. The clip 105 has a pair of left and right support pillars 111A and 111B protruding from a dish part 110 protruding from the outer surface of the main body 103, and a bridging part 112 connecting the protruding ends of the pair of support pillars 111A and 111B. A pair of blade portions 113A and 113B are projected in a folded manner toward the base portion 110 on both sides of the direction (width direction) Y and in the longitudinal direction X to the left and right, and the blade portions 113A and 113B A plurality of steps (three steps) of locking claws 114A and 114B are provided on the outer surface. Moreover, the center connection part 116 which connects the adjacent inner ends of blade part 113A and 113B is provided.

前記バンドクリップ１００は締結バンド１０２を図９（Ｃ）に示すようにワイヤハーネス１２０の電線群に巻き付けた後、本体１０３のバンド貫通穴１０３ａに通し、締結バンド１０２に設けた係止溝１０２ａにバンド貫通穴１０３ａに突設した係止片を係止してワイヤハーネス１２０に締結している。ワイヤハーネス１２０を自動車の車体に沿って配索し、車体パネルＰに予め設けている長円状の取付穴Ｈにクリップ１０５を挿入し、羽根部１１３Ａ、１１３Ｂを取付穴Ｈに撓ませて押し込み、係止爪１１４Ａ、１１４Ｂを取付穴Ｈの長手方向Ｘの周縁に係止して、取付穴Ｈに固定している。   In the band clip 100, the fastening band 102 is wound around the wire group of the wire harness 120 as shown in FIG. The locking piece protruding from the band through hole 103 a is locked and fastened to the wire harness 120. The wire harness 120 is routed along the vehicle body, the clip 105 is inserted into an oval mounting hole H provided in advance in the vehicle body panel P, and the blade portions 113A and 113B are bent and pushed into the mounting hole H. The locking claws 114A and 114B are locked to the peripheral edge in the longitudinal direction X of the mounting hole H and fixed to the mounting hole H.

前記バンドクリップ１００は羽根部１１３Ａと１１３Ｂとを薄肉の可撓性を有する中央連結部１１６で連結しているため、ワイヤハーネス１２０に短手方向Ｙの引張力が作用し、羽根部１１３Ａ、１１３Ｂが短手方向の一方側に傾く力が作用しても、中央連結部１１６による戻し方向の引張力で羽根部の傾きが抑制され、羽根部の係止爪による取付穴への係止力を保持することができる。   In the band clip 100, the blade portions 113A and 113B are connected by a thin and flexible central connecting portion 116. Therefore, a tensile force in the short direction Y acts on the wire harness 120, and the blade portions 113A and 113B. Even if a force that inclines to one side in the short direction is applied, the inclination of the blade portion is suppressed by the pulling force in the return direction by the central connecting portion 116, and the locking force to the mounting hole by the locking claw of the blade portion is reduced. Can be held.

特開２０１０−１５１１７４号公報JP 2010-151174 A

しかしながら、図１０（Ａ）に示すように、前記バンドクリップ１００のクリップ１０５を取付穴Ｈに押し込む際に、取付穴Ｈとの位置関係で、羽根部１１３Ａ、１１３Ｂ（図示では１１３Ａ）の一方の係止爪１１４Ａ、１１４Ｂ（図示では１１４Ａ）が取付穴Ｈの周縁で押し過ぎてしまう場合がある。この場合、羽根部１１３Ａ、１１３Ｂの中央側端が可撓性を有する中央連結部１１６で連結されているだけであり、羽根部が当接する支柱等の壁が無いため、図１０（Ｂ）に示すように、架橋部１１２との連結部位Ｚが曲げポイントとなって羽根部１１３Ａが内側へ倒れ込みやすい。該内側への倒れ込みが大きくなると、図１０（Ｃ）に示す点線位置から実線位置へと塑性変形が発生して係止爪１１４Ａが戻りにくくなる。その結果、車体パネルＰの取付穴Ｈの周縁に係止爪１１４Ａが掛からなくなり、バンドクリップ１００を車体パネルＰに係止できなくなる可能性がある。   However, as shown in FIG. 10A, when the clip 105 of the band clip 100 is pushed into the mounting hole H, one of the blade portions 113A and 113B (113A in the drawing) is positioned in relation to the mounting hole H. The locking claws 114 </ b> A and 114 </ b> B (114 </ b> A in the drawing) may be pushed too much at the periphery of the mounting hole H. In this case, the central side ends of the blade portions 113A and 113B are only connected by the flexible central connection portion 116, and there is no wall such as a column with which the blade portions abut. As shown, the connecting portion Z with the bridging portion 112 becomes a bending point, and the blade portion 113A tends to fall inward. When the inward tilt is increased, plastic deformation occurs from the dotted line position shown in FIG. 10C to the solid line position, and the locking claw 114A is difficult to return. As a result, there is a possibility that the locking claw 114A is not hooked around the periphery of the mounting hole H of the vehicle body panel P, and the band clip 100 cannot be locked to the vehicle body panel P.

前記問題は係止爪１１４Ａ、１１４Ｂを肉盛りし、係止爪が変形しても取付穴Ｈの周縁に掛かるようにすれば解決できるが、係止爪を肉盛りすると、取付穴Ｈへのクリップの挿入力が上がることになり、取り付け作業性が悪くなる問題がある。   The problem can be solved by building up the latching claws 114A and 114B so that the latching claws are deformed so that they are hooked on the periphery of the mounting hole H. However, if the latching claws are built up, There is a problem that the insertion force of the clip is increased and the mounting workability is deteriorated.

本発明は前記した問題に鑑みてなされたもので、バンドクリップのクリップを車体パネルの取付穴に挿入係止する際、係止爪が押され過ぎて内方へ変形しても、挿入力を増大させることなく、取付穴の周縁に係止爪が確実に掛かるようにして、バンドクリップの係止信頼性を高めることを課題としている。   The present invention has been made in view of the above problems, and when inserting and locking the clip of the band clip into the mounting hole of the vehicle body panel, even if the locking claw is pushed too much and deforms inward, the insertion force is increased. It is an object to increase the locking reliability of the band clip by ensuring that the locking claw is securely hooked around the periphery of the mounting hole without increasing it.

前記課題を解決するため、本発明は、締結バンドを設けたワイヤハーネス取付部から突設する一対の支柱部の突出端を連結する架橋部に、短手方向の両側で且つ長手方向の左右に位相させて一対の羽根部を前記ワイヤハーネス取付部側の基部側に向けて折り返し状に突設し、各羽根部の外面に係止爪を設け、該係止爪を車体の取付穴の周縁に係止するバンドクリップにおいて、
前記羽根部のワイヤハーネス取付部側の下部に、最下段の前記係止爪の係止面の内端から下方に突出して前記取付穴の内周面と対向させる下部脚部を備え、該下部脚部の外面に下向きに広がる三角形状の傾斜突起を設けると共に、前記下部脚部の内面から前記傾斜突起の上端側に向けて楔状の切込を設け、
前記羽根部および係止爪が過度に押されて内方へ倒れ込むと前記傾斜突起の傾斜外面が垂直面となる一方、前記傾斜突起が内方へ押されるだけであると前記切欠を閉じて傾斜突起の傾斜外面が垂直方向となり、該垂直面となる傾斜突起の傾斜外面を前記車体の取付穴の内周面に密接できる構成としていることを特徴とするワイヤハーネス用のバンドクリップを提供している。 In order to solve the above-mentioned problems, the present invention provides a bridging portion that connects the protruding ends of a pair of support columns protruding from a wire harness mounting portion provided with a fastening band, on both sides in the short direction and on the left and right in the longitudinal direction. A pair of blade portions are projected in a folded manner toward the base side on the wire harness mounting portion side in phase, and locking claws are provided on the outer surface of each blade portion, and the locking claws are arranged at the periphery of the mounting hole of the vehicle body. In the band clip locked to
The lower portion of the blade portion on the wire harness mounting portion side includes a lower leg portion that protrudes downward from the inner end of the locking surface of the lowermost locking claw and faces the inner peripheral surface of the mounting hole. Provided with a triangular inclined projection extending downward on the outer surface of the leg portion, and provided a wedge-shaped cut from the inner surface of the lower leg portion toward the upper end side of the inclined projection,
When the blade part and the locking claw are pushed excessively and fall down inward, the inclined outer surface of the inclined projection becomes a vertical surface, whereas when the inclined projection is only pushed inward, the notch is closed and inclined. Provided is a band clip for a wire harness, characterized in that the inclined outer surface of the protrusion is in a vertical direction, and the inclined outer surface of the inclined protrusion serving as the vertical surface can be in close contact with the inner peripheral surface of the mounting hole of the vehicle body. Yes.

前記のように、最下段の係止爪の係止面内端から延在する前記下部脚部の外面に傾斜突起を突出しておくと、羽根部全体が取付穴の周縁で内方へ押され過ぎて係止爪が内方へと倒れ込むように塑性変形が発生しても、前記傾斜突起の傾斜外面が垂直面となるため、取付穴の内周面に当接させることができ、該下部脚部の上部に連続する係止爪の係止面を取付穴の周縁に当接させてしっかりと係止することができる。
また、クリップの挿入位置が正常で、羽根部の係止爪が取付穴の内周面で過度に押されない場合には、下部脚部の傾斜突起のみが取付穴の内周面に押されて前記切欠を閉じて、下部脚部の傾斜外面が垂直面となり、取付穴の内周面に当接させることができる。よって、下部脚部の外面に突設した傾斜突起が取付穴の内周面との当接で邪魔になることはなく、クリップを車体パネルの取付穴にガタつき無く係止することができる。 As described above, if the inclined protrusion is projected on the outer surface of the lower leg portion extending from the inner end of the locking surface of the lowermost locking claw, the entire blade portion is pushed inward at the periphery of the mounting hole. Even if plastic deformation occurs so that the latching claw falls down inward, the inclined outer surface of the inclined protrusion becomes a vertical surface, so that it can be brought into contact with the inner peripheral surface of the mounting hole. The locking surface of the locking claw continuous with the upper part of the leg can be brought into contact with the peripheral edge of the mounting hole and locked firmly.
In addition, when the clip insertion position is normal and the locking pawls of the blades are not pushed excessively on the inner peripheral surface of the mounting hole, only the inclined projections on the lower leg are pressed against the inner peripheral surface of the mounting hole. By closing the notch, the inclined outer surface of the lower leg portion becomes a vertical surface and can be brought into contact with the inner peripheral surface of the mounting hole. Therefore, the inclined protrusion protruding from the outer surface of the lower leg portion does not get in the way of contact with the inner peripheral surface of the mounting hole, and the clip can be locked to the mounting hole of the vehicle body panel without backlash.

前記傾斜突起は前記下部脚部の外面の全長に設け、最下段の係止爪の係止面内端を上頂点とした直角三角形の形状で、底辺の外方突出端は前記係止爪の外方突出端から外方に突出させず、かつ、
前記下部脚部の上部に内面側から切り込んで形成する前記切欠は、前記係止爪の係止面内端との間に少なくとも０．５ｍｍ以上の間隔を残していることが好ましい。 The inclined projection is provided on the entire length of the outer surface of the lower leg, and has a right triangle shape with the inner end of the locking surface of the lowermost locking claw as an upper vertex, and the outward protruding end of the bottom is the locking claw. Do not protrude outward from the outwardly protruding end, and
It is preferable that the notch formed by cutting from the inner surface side into the upper portion of the lower leg portion leaves a gap of at least 0.5 mm or more with the inner end of the locking claw.

前記一対の羽根部の外面に上下複数段で係止爪を設け、該係止爪は羽根部の外面にＶ形状の切込みを設けて三角形状の係止爪とし、上段側の係止爪の外方突出量を漸次大とし、前記最下段の係止爪の係止面の内端から前記下部脚部を突設していることが好ましい。
なお、羽根部に設ける係止爪は１段のみでもよく、その場合には、該１段の係止爪が前記最下段の係止爪に相当する。 The outer claws of the pair of blades are provided with a plurality of upper and lower locking claws, and the locking claws are provided with V-shaped cuts on the outer surfaces of the blades to form triangular hooks. It is preferable that the outward protrusion amount is gradually increased, and the lower leg portion is protruded from the inner end of the locking surface of the lowermost locking claw.
In addition, the latching claw provided in a blade | wing part may be only one step, and in that case, the one-step latching claw corresponds to the bottommost latching claw.

前記バンドクリップは比較的撓みやすいポリプロピレン等で樹脂成形している。
前記ワイヤハーネス取付部は前記締結バンドを突設した本体部の外面に皿部を突設し、該皿部の底面より前記一対の支柱部を突設し、かつ、前記一対の羽根部は互いに近接内側端で且つ前記皿部側端を中央連結部で連結していることが好ましい。
前記した中央連結部を設けると、クリップに短軸方向の引張力が作用した時にクリップを取付穴から抜き出にくくできる。 The band clip is resin-molded with relatively flexible polypropylene or the like.
The wire harness mounting part projects a dish part on the outer surface of the main body part projecting the fastening band, projects the pair of column parts from the bottom surface of the dish part, and the pair of blade parts mutually It is preferable that the near inner end and the dish part side end are connected by a central connecting part.
Providing the above-described central connecting portion makes it difficult to pull out the clip from the mounting hole when a tensile force in the short axis direction acts on the clip.

前記のように、本発明に係わるバンドクリップは一対の羽根部に設ける係止爪の下端から延在する前記下部脚部の外面に傾斜突起を設けると共に、該下部脚部の上部内面から切欠を設けているため、前記傾斜突起のみが内方へ押されると前記切欠を閉じて傾斜突起の傾斜外面が垂直方向となり、また、係止爪を含めて羽根部全体が内方へ過度に押されて、内方へ倒れ込む状態となると前記傾斜突起の傾斜外面が垂直面となる。このように、いずれの場合も下部脚部の外面を垂直面として車体パネルの取付穴の内周面に密接させることができる。これにより、クリップを車体パネルの取付穴にガタつきなく安定姿勢で係止できる。   As described above, the band clip according to the present invention is provided with the inclined protrusion on the outer surface of the lower leg portion extending from the lower end of the locking claw provided on the pair of blade portions, and the notch is formed on the upper inner surface of the lower leg portion. Therefore, when only the inclined protrusion is pushed inward, the notch is closed and the inclined outer surface of the inclined protrusion becomes vertical, and the entire blade part including the locking claw is pushed excessively inward. Thus, when it falls into the inward direction, the inclined outer surface of the inclined protrusion becomes a vertical surface. Thus, in any case, the outer surface of the lower leg portion can be brought into close contact with the inner peripheral surface of the mounting hole of the vehicle body panel as a vertical surface. Accordingly, the clip can be locked in a stable posture without rattling in the mounting hole of the vehicle body panel.

また、下部脚部１８、１９の上部側の内面から楔状の切欠２２、２３を切り込んで形成している。該切欠２２、２３の内端と前記係止面１６−３ｓ、１７−３ｓの内端とは隙間Ｌ２をあけて同一高さ位置に設けている。該隙間Ｌ２は０．５ｍｍ以上とし、切欠２２、２３の内端と前記係止面１６−３ｓ、１７−３ｓの内端との間で亀裂が発生しないようにしている。   In addition, wedge-shaped notches 22 and 23 are cut from the upper inner surfaces of the lower legs 18 and 19. The inner ends of the notches 22 and 23 and the inner ends of the locking surfaces 16-3s and 17-3s are provided at the same height position with a gap L2. The gap L2 is 0.5 mm or more so that cracks do not occur between the inner ends of the notches 22 and 23 and the inner ends of the locking surfaces 16-3s and 17-3s.

前記下部脚部１８、１９に設ける傾斜突起２０、２１と切欠２２、２３とは、切欠２２、２３が閉じると、傾斜突起２０、２１の傾斜外面２０ｂ、２１ｂが垂直方向（前記支柱部１１、１２の突出方向）となるように設定している。   The inclined protrusions 20 and 21 and the notches 22 and 23 provided on the lower legs 18 and 19 are such that when the notches 22 and 23 are closed, the inclined outer surfaces 20b and 21b of the inclined protrusions 20 and 21 are in the vertical direction (the support column part 11 and 12 projecting directions).

前記左右一対の支柱部１１、１２は長円形状の取付穴Ｈ内において、短辺側にそれぞれ内嵌する断面半円形状としている。該左右一対の支柱部１１、１２の対向する平坦面からなる内面１１ａ、１２ａの間に、前記羽根部１４、１５を配置している。
羽根部１４、１５は、前記のように、長手方向Ｘで左右に位相させていると共に、近接する内側縁の間に隙間をあけ、一方の羽根部１４は一方の支柱部１１に近接させ、他方の羽根部１５は他方の支柱部１２に近接させている。 The pair of left and right support columns 11 and 12 have a semicircular cross section that fits inside the oval mounting hole H on the short side. The blade portions 14 and 15 are disposed between inner surfaces 11a and 12a formed of flat surfaces of the pair of left and right support columns 11 and 12 which face each other.
As described above, the blade portions 14 and 15 are phased to the left and right in the longitudinal direction X, and a gap is formed between adjacent inner edges, and one blade portion 14 is brought close to one strut portion 11, The other blade portion 15 is brought close to the other strut portion 12.

前記構成としたバンドクリップ１は図５に示すように、締結バンド６をワイヤハーネスＷ／Ｈを構成する電線群Ｗに巻き付けた後、本体５のバンド貫通穴５ａに通し、バンド貫通穴５ａ内で係止溝６ａに係止片を係止してワイヤハーネスＷ／Ｈに固定している。
該ワイヤハーネスＷ／Ｈを車体の配索経路に沿って配索し、車体パネルＰに設けた長円形状の取付穴Ｈに前記バンドクリップ１のクリップ３を架橋部１３側から押し込み、羽根部１４、１５の係止爪１６、１７を取付穴Ｈの内周縁に係止して固定している。 As shown in FIG. 5, the band clip 1 having the above-described configuration is wound around the wire group W constituting the wire harness W / H, and then passed through the band through hole 5a of the main body 5 and then into the band through hole 5a. Thus, the locking piece is locked in the locking groove 6a and fixed to the wire harness W / H.
The wire harness W / H is routed along the routing route of the vehicle body, the clip 3 of the band clip 1 is pushed into the oval mounting hole H provided in the vehicle body panel P from the bridge portion 13 side, and the blade portion The locking claws 16 and 17 of 14 and 15 are locked and fixed to the inner peripheral edge of the mounting hole H.

詳細には、本実施形態では、車体パネルＰの板厚が薄いため、クリップ３の取付穴Ｈへの挿入位置の精度が良いと、図５（Ｃ）に示すように、最下段の３段目の係止爪１６−３が取付穴Ｈの対向する一方の長辺ｈａの左側に係止し、係止爪１７−３が取付穴Ｈの対向する他方の長辺ｈｂの右側に係止する。また、取付穴Ｈの左右の短辺側の円弧部の内面に沿って支柱部１１、１２が内嵌する。   In detail, in this embodiment, since the plate | board thickness of the vehicle body panel P is thin, if the precision of the insertion position to the attachment hole H of the clip 3 is good, as shown in FIG.5 (C), as shown in FIG. The locking claw 16-3 of the eye is locked to the left side of the one long side ha opposite to the mounting hole H, and the locking claw 17-3 is locked to the right side of the other long side hb of the mounting hole H facing each other. To do. Moreover, the support | pillar parts 11 and 12 fit in along the inner surface of the circular-arc part by the side of the short side of the right and left of the attachment hole H.

前記したクリップ３の挿入位置が取付穴Ｈと位置ずれしていない正常な挿入位置であると、図６（Ａ）（Ｂ）に示すように、クリップ３の下部脚部１８の外面から突出する傾斜突起２０が取付穴Ｈの内周面Ｈｉを内方へと押し込むように作用する。該作用で下部脚部１８が内方へ切欠２２を閉じていき、傾斜突起２０の傾斜外面２０ｂがほぼ垂直面となる。よって、車体パネルＰの取付穴Ｈの内周面Ｈｉはほぼ垂直面となった傾斜外面２０ｂに当接する。かつ、該下部脚部１８の上部に連続する係止爪１６−３は取付穴Ｈの内周縁に係止する。クリップ３が車体パネルＰにしっかりと係止されることになる。
他方の羽根部１５の下部脚部１９に設けた傾斜突起２１も前記傾斜突起２０と同様に、切欠２３を閉じて垂直面となり、取付穴Ｈの内周面に当接する。 When the insertion position of the clip 3 described above is a normal insertion position that is not displaced from the mounting hole H, the clip 3 protrudes from the outer surface of the lower leg portion 18 of the clip 3 as shown in FIGS. The inclined protrusion 20 acts to push the inner peripheral surface Hi of the mounting hole H inward. With this action, the lower leg 18 closes the notch 22 inward, and the inclined outer surface 20b of the inclined protrusion 20 becomes a substantially vertical surface. Therefore, the inner peripheral surface Hi of the mounting hole H of the vehicle body panel P is in contact with the inclined outer surface 20b which is a substantially vertical surface. And the latching claw 16-3 which continues to the upper part of this lower leg part 18 latches to the inner periphery of the attachment hole H. FIG. The clip 3 is firmly locked to the vehicle body panel P.
Similarly to the inclined protrusion 20, the inclined protrusion 21 provided on the lower leg portion 19 of the other blade part 15 closes the notch 23 to become a vertical surface and abuts against the inner peripheral surface of the mounting hole H.

一方、クリップ３の挿入位置が取付穴Ｈと位置ずれしている場合、羽根部１４、１５のいずれか一方、例えば、図７（Ａ）（Ｂ）に示すように、羽根部１４の全体が取付穴Ｈの周縁に強く押され、設定した圧力より押され過ぎとなり、羽根部１４が取付穴Ｈの内方へ倒れ込むようになり、下部脚部１８も内方に向けて傾斜する。該傾斜した下部脚部１８の外面に設けた傾斜突起２０自体も傾斜するため、傾斜外面２０ｂが垂直面となる。よって、車体パネルＰの取付穴Ｈの内周面Ｈｉは垂直面となった傾斜外面２０ｂに当接すると共に、該下部脚部１８の上部に連続する係止爪１６−３は取付穴Ｈの内周縁に係止する。これにより、クリップ３が車体パネルＰにしっかりと係止できる。   On the other hand, when the insertion position of the clip 3 is displaced from the mounting hole H, as shown in FIGS. 7A and 7B, for example, as shown in FIGS. It is strongly pressed by the peripheral edge of the mounting hole H and becomes excessively pressed by the set pressure, so that the blade part 14 falls down inward of the mounting hole H, and the lower leg part 18 is also inclined inward. Since the inclined projection 20 itself provided on the outer surface of the inclined lower leg portion 18 is also inclined, the inclined outer surface 20b becomes a vertical surface. Therefore, the inner peripheral surface Hi of the mounting hole H of the vehicle body panel P is in contact with the inclined outer surface 20b which is a vertical surface, and the locking claw 16-3 continuous to the upper portion of the lower leg portion 18 has an inner portion of the mounting hole H. Lock to the periphery. Thereby, the clip 3 can be firmly locked to the vehicle body panel P.

車体パネルＰの板厚が比較的厚く、２段目の係止爪１６−２、１７−２または、上段の１段目の係止爪１６−１、１７−１を車体パネルＰに係止する場合も同様で、下部脚部１８、１９の傾斜突起２０、２１の傾斜外面は正常挿入時および位置ずれ挿入時のいずれも垂直面となり、厚さが大となった取付穴Ｈの内周面に接触させることができ、ガタツキなくクリップ３を取付穴Ｈに係止できる。   The body panel P is relatively thick, and the second level locking claws 16-2 and 17-2 or the upper level locking claws 16-1 and 17-1 are locked to the vehicle body panel P. The inclined outer surfaces of the inclined protrusions 20 and 21 of the lower legs 18 and 19 are both vertical surfaces during normal insertion and misalignment insertion, and the inner circumference of the mounting hole H having a large thickness. The clip 3 can be brought into contact with the surface, and the clip 3 can be locked in the mounting hole H without rattling.
