しかしながら、特許文献１のプロテクタによると、被係止部と係止部との係合時に加わる力により、力を作用させる押リブの上面から被係止部までの部分に対して撓みが発生する恐れがある。特に、軽量化及び材料費の軽減等の課題に鑑みて薄肉化されているプロテクタにおいては、その影響は顕著に現れると推測される。   However, according to the protector of Patent Document 1, due to the force applied when the locked portion and the locking portion are engaged, the portion from the upper surface of the push rib on which the force is applied to the locked portion is generated. There is a fear. In particular, in the case of a protector that is thinned in view of problems such as weight reduction and reduction of material costs, it is speculated that the effect appears remarkably.

なお、特許文献１において、被係止部が基端部でカバー体の外周側に重なるように***して設けられているが、この***高さは小さく、作業者が直接手で押すことは困難である。   In Patent Document 1, the locked portion is provided so as to be raised at the base end portion so as to overlap the outer peripheral side of the cover body. However, the height of the raised portion is small, and the operator does not press it directly by hand. Have difficulty.

また、特許文献１のプロテクタは断面視円形状であるが、カバー体の側壁部が被係止部の係合方向に延在する形状のプロテクタの場合、側壁部の上面を押して係合作業を行うと考えられるが、この側壁部の突出寸法が長いほど側壁部の上面から被係止部までの距離は長くなり、当該部分が撓み易くなってしまう。   Moreover, although the protector of patent document 1 is circular cross-sectional view, in the case of the protector of the shape where the side wall part of a cover body is extended in the engaging direction of a to-be-latched part, an upper surface of a side wall part is pushed and engagement work is carried out. Although it is thought that this is done, the longer the projecting dimension of the side wall, the longer the distance from the upper surface of the side wall to the locked part, and the part becomes more easily bent.

このように、プロテクタの組立時に作用させる力によりプロテクタが撓んでしまうと、被係止部と係止部とを係合させ難くなり、作業性が低下する恐れがある。   Thus, if the protector bends due to the force applied at the time of assembling the protector, it becomes difficult to engage the locked portion and the locking portion, and workability may be reduced.

そこで、本発明は、プロテクタの組立作業性を向上させることを目的とする。   Accordingly, an object of the present invention is to improve the assembling workability of the protector.

第２の態様に係るプロテクタは、第１の態様に係るプロテクタであって、前記押圧部は、前記係止方向に直交する押圧面を有している。   The protector which concerns on a 2nd aspect is a protector which concerns on a 1st aspect, Comprising: The said press part has a press surface orthogonal to the said locking direction.

第３の態様に係るプロテクタは、第２の態様に係るプロテクタであって、前記押圧部は、前記係止方向に直交する扁平形状に形成され、前記押圧面のうち少なくとも一部を前記第２本体部の外面に対して連結する補強リブを備えている。   The protector which concerns on a 3rd aspect is a protector which concerns on a 2nd aspect, Comprising: The said press part is formed in the flat shape orthogonal to the said locking direction, and at least one part among the said press surfaces is said 2nd. Reinforcing ribs connected to the outer surface of the main body are provided.

第４の態様に係るプロテクタは、第１〜第３の態様のいずれか一態様に係るプロテクタであって、前記押圧部は、前記係止方向において、前記第２本体部と前記延出片との境界の位置から突出している。 Protector according to a fourth aspect is a protector according to any one aspect of the first to third embodiments, the front Symbol pressing portion in the locking direction, the second body portion and the extension piece And protrudes from the boundary position.

また、第１の態様に係るプロテクタの前記係止部は、前記第２本体部の側端部から前記係止方向前方に向けて延出する延出片を有し、前記係止突部は、前記延出片の先端側部分から前記押圧部と同じ向きに突出するように形成され、前記被係止部は、補助壁部と、前記補助壁部に対して前記延出片を挿入可能な間隔をあけて設けられ、前記係止方向前方を向く被係止面を有する主壁部とを有し、前記押圧部は、前記係止突部が前記主壁部の前記被係止面に係止した状態で、前記主壁部の前記係止方向後方端部に当接可能な位置に形成されている。 Further, the locking portion of the protector according to the first embodiment has an extending piece extending toward the locking direction forward from the side end portion of the second body portion, the locking projection is The extension piece is formed so as to protrude in the same direction as the pressing portion from the tip side portion of the extension piece, and the locked portion can be inserted into the auxiliary wall portion and the auxiliary wall portion. And a main wall portion having a locked surface facing forward in the locking direction, and the pressing portion has the locking protrusion on the locked surface of the main wall portion. In a state where the main wall portion is engaged with the main wall portion, the main wall portion is formed at a position where the main wall portion can contact the rear end portion in the engaging direction.

第１の態様に係るプロテクタによると、押圧部が、第２本体部又は係止部のうち係止突部に対して係止方向後方の位置から、係止突部の基端部より側方に突出するように形成されている。このため、係止部を被係止部に係止させる際に係止方向に力を加えやすく、係止時に第２本体部の撓みを抑制することができる。これにより、プロテクタの組立作業性を向上させることができる。   According to the protector which concerns on a 1st aspect, a press part is a side rather than the base end part of a latching protrusion from the position behind a latching protrusion with respect to a latching protrusion among 2nd main-body parts or a latching part. It is formed so as to protrude. For this reason, it is easy to apply a force in the locking direction when the locking portion is locked to the locked portion, and bending of the second main body portion can be suppressed during locking. Thereby, the assembly workability | operativity of a protector can be improved.

第２の態様に係るプロテクタによると、押圧部が係止方向に直交する押圧面を有しているため、より係止方向に力を作用させやすく、係止部を被係止部に係止させる際の作業性を向上させることができる。   According to the protector which concerns on a 2nd aspect, since the press part has a press surface orthogonal to a locking direction, it is easy to make force act on a locking direction, and locks a locking part to a to-be-latched part. The workability at the time of making it can be improved.

第３の態様に係るプロテクタによると、補強リブが、扁平形状に形成されている押圧部の押圧面のうち少なくとも一部を第２本体部の外面に対して連結するように形成されているため、押圧部を押圧する際に押圧部が撓むことを抑制できる。   According to the protector which concerns on a 3rd aspect, since the reinforcement rib is formed so that at least one part may be connected with the outer surface of a 2nd main-body part among the press surfaces of the press part currently formed in the flat shape. When the pressing portion is pressed, the pressing portion can be prevented from being bent.

第４の態様に係るプロテクタによると、押圧部が、係止方向において、第２本体部と先端側部分に係止突部が設けられた延出片との境界の位置から突出するように形成されている。このため、係止作業時に、係止突部に対してなるべく近い位置で力を作用させることができ、第２本体部の撓みをより効果的に抑制することができる。   According to the protector which concerns on a 4th aspect, it forms so that a press part may protrude from the position of a boundary with the extension piece in which the latching protrusion was provided in the front-end | tip part in the latching direction. Has been. For this reason, at the time of the locking operation, a force can be applied at a position as close as possible to the locking projection, and the bending of the second main body can be more effectively suppressed.

また、第１の態様に係るプロテクタによると、押圧部は、係止突部が主壁部の被係止面に係止した状態で、主壁部の係止方向後方端部に当接可能な位置に形成されている。このため、係止突部が被係止部に係止した状態で、係止部と被係止部との係止方向両側における相対移動を規制することができ、がたつきを抑制してより確実に係止状態を維持することができる。

 Moreover, according to the protector which concerns on a 1st aspect, a press part can contact | abut to the latching direction back end part of the main wall part in the state which the latching protrusion locked on the to-be-latched surface of the main wall part. It is formed in the position. For this reason, in the state where the locking protrusion is locked to the locked portion, the relative movement of the locking portion and the locked portion on both sides in the locking direction can be restricted, and rattling is suppressed. The locked state can be maintained more reliably.

以下、実施形態に係るプロテクタ１０について説明する（図１参照）。プロテクタ１０は、車両等に配索されるワイヤーハーネスＷＨを、周囲から保護すると共に形状維持するための部材である。   Hereinafter, the protector 10 according to the embodiment will be described (see FIG. 1). The protector 10 is a member for protecting the wire harness WH routed in a vehicle or the like from the surroundings and maintaining the shape.

本プロテクタ１０は、本体部２０と、ロック構造部４０と、押圧部６０と、補強リブ７０とを備えている。   The protector 10 includes a main body portion 20, a lock structure portion 40, a pressing portion 60, and reinforcing ribs 70.

本体部２０は、合体可能な第１本体部２２と第２本体部３２とを有している（図１参照）。この本体部２０は、合体状態で第１本体部２２と第２本体部３２との間にワイヤーハーネスＷＨを収容可能に形成されている。   The main body 20 includes a first main body 22 and a second main body 32 that can be combined (see FIG. 1). The main body 20 is formed so as to accommodate the wire harness WH between the first main body 22 and the second main body 32 in the combined state.

本体部２０は、ワイヤーハーネスＷＨの配索形態（配設箇所の形状）に対応した形状に形成され、内部に収容されるワイヤーハーネスＷＨを外部から保護すると共に配索形態を維持可能になっている。本体部２０を構成する第１本体部２２と第２本体部３２との組合せとしては、例えば、断面視Ｕ字形（半円形も含む）の凹状部材の組合せ、凹状部材と蓋状部材との組合せ、断面視Ｌ字形部材の組合せ等、配設箇所に対応した形状を成す種々の形状の組合せを採用することができる。また、本体部２０は、ワイヤーハーネスＷＨの分岐部分を保護及び形態維持するものでもよく、この場合、当該分岐部分のうち保護及び形態維持の対象となる部分に対応した形状を成す第１本体部と第２本体部との組合せが採用されるとよい。   The main body 20 is formed in a shape corresponding to the wiring form of the wire harness WH (the shape of the arrangement location), and protects the wire harness WH housed inside from the outside and can maintain the wiring form. Yes. Examples of the combination of the first main body 22 and the second main body 32 constituting the main body 20 include a combination of U-shaped (including semicircular) concave members, and a combination of a concave member and a lid-shaped member. Various combinations of shapes that form shapes corresponding to the arrangement locations, such as combinations of L-shaped members in cross-sectional view, can be employed. Moreover, the main body part 20 may protect and maintain the branch part of the wire harness WH. In this case, the first main body part having a shape corresponding to the part to be protected and maintained in the form of the branch part. A combination of the second main body portion and the second main body portion may be employed.

ここでは、説明の便宜上、第１本体部２２及び第２本体部３２が断面視Ｕ字形の凹状部材であって、合体時に本体部２０が全体として略角筒状に形成されているものとする。すなわち、第１本体部２２及び第２本体部３２は、概略的には、それぞれ、板状の基部の両側端部に沿って側壁部が立設されている形状である。また、ここでは、第１本体部２２及び第２本体部３２は、各一方の側壁部からその外方に突出する部分を有している例で説明する。   Here, for convenience of explanation, it is assumed that the first main body portion 22 and the second main body portion 32 are U-shaped concave members in cross section, and the main body portion 20 is formed in a substantially rectangular tube shape as a whole when combined. . That is, the first main body portion 22 and the second main body portion 32 are each generally shaped such that side wall portions are erected along both side end portions of the plate-like base portion. In addition, here, the first main body portion 22 and the second main body portion 32 will be described as an example having a portion protruding outward from each one of the side wall portions.

第１本体部２２と第２本体部３２とは、別々の部材として形成されていてもよいし、ヒンジにより開閉可能に連結された一体部材として形成されていてもよい。ここでは、第１本体部２２と第２本体部３２とが別々の部材として形成されている例で説明する。   The 1st main-body part 22 and the 2nd main-body part 32 may be formed as a separate member, and may be formed as an integral member connected so that opening and closing is possible by the hinge. Here, an example in which the first main body portion 22 and the second main body portion 32 are formed as separate members will be described.

そして、第１本体部２２と第２本体部３２とは、近接させることにより各側端部（各側壁部の先端側部分）を突き合わせる形態で合体されて本体部２０を構成するように形成されている。ここで、第１本体部２２及び第２本体部３２について、合体される際に突き合わされる各側端部同士が近接する方向を合体方向（図１の上下方向）という。なお、第１本体部２２と第２本体部３２とがヒンジにより開閉される構成の場合、開閉軸周りの周方向において、突き合わされる側端部同士が近接する方向が合体方向である。   And the 1st main-body part 22 and the 2nd main-body part 32 are united in the form which butts each side edge part (tip side part of each side wall part) by making it adjoin, and it forms so that the main-body part 20 may be comprised. Has been. Here, about the 1st main-body part 22 and the 2nd main-body part 32, the direction in which each side edge part faced | matched when it unites | combines is called unification direction (up-down direction of FIG. 1). In the case where the first main body portion 22 and the second main body portion 32 are configured to be opened and closed by a hinge, the direction in which the side end portions to be abutted with each other in the circumferential direction around the opening / closing axis is the coalescence direction.

プロテクタ１０には、本体部２０の合体状態を維持するために、ロック構造部４０が設けられている（図２参照）。このロック構造部４０は、第１本体部２２に設けられた被係止部４２と、第２本体部３２に設けられた係止部５２とを有している。以下、ロック構造部４０について、本体部２０の一側部に設けられる一つに着目して説明する。   The protector 10 is provided with a lock structure 40 in order to maintain the united state of the main body 20 (see FIG. 2). The lock structure portion 40 includes a locked portion 42 provided in the first main body portion 22 and a locking portion 52 provided in the second main body portion 32. Hereinafter, the lock structure 40 will be described by focusing on one provided on one side of the main body 20.

ロック構造部４０は、係止部５２を被係止部４２に対して係止方向Ｌに近接させることにより係止可能に構成されている。ここでは、係止方向Ｌは、第１本体部２２と第２本体部３２との合体方向と略同方向に設定されている（図１参照）。すなわち、係止部５２は、第１本体部２２と第２本体部３２との合体動作に伴って被係止部４２に対して係止するように形成されている。   The lock structure part 40 is configured to be able to be locked by bringing the locking part 52 close to the locked part 42 in the locking direction L. Here, the locking direction L is set in substantially the same direction as the direction in which the first main body portion 22 and the second main body portion 32 are combined (see FIG. 1). In other words, the locking portion 52 is formed to be locked with respect to the locked portion 42 in accordance with the combined operation of the first main body portion 22 and the second main body portion 32.

被係止部４２は、補助壁部４４と当該補助壁部４４に対して間隔をあけて設けられた主壁部４６とを有している（図４〜図７参照）。ここでは、補助壁部４４は、第１本体部２２の側壁部の一部であり、その一側端部に位置している。主壁部４６は、補助壁部４４に略平行で、且つ、係止方向Ｌに略直交する方向に延在するように設けられた帯状の壁部である。この主壁部４６は、補助壁部４４に対して、延在方向両端部が一対の支持片４８により支持されている。また、主壁部４６と補助壁部４４との間隔は、後述する係止部５２の延出片５４を挿入可能な大きさに設定されている。また、補助壁部４４は、係止方向Ｌにおいて、主壁部４６より大きい寸法に（係止方向Ｌ前方に大きく）形成されている。   The locked portion 42 includes an auxiliary wall portion 44 and a main wall portion 46 that is provided at an interval from the auxiliary wall portion 44 (see FIGS. 4 to 7). Here, the auxiliary wall portion 44 is a part of the side wall portion of the first main body portion 22 and is located at one end portion thereof. The main wall portion 46 is a belt-like wall portion provided so as to extend in a direction substantially parallel to the auxiliary wall portion 44 and substantially perpendicular to the locking direction L. The main wall portion 46 is supported by a pair of support pieces 48 at both ends in the extending direction with respect to the auxiliary wall portion 44. Moreover, the space | interval of the main wall part 46 and the auxiliary | assistant wall part 44 is set to the magnitude | size which can insert the extension piece 54 of the latching | locking part 52 mentioned later. Further, the auxiliary wall portion 44 is formed in a size larger than the main wall portion 46 in the locking direction L (largely in front of the locking direction L).

ここで、主壁部４６のうち、係止方向Ｌ前方の端面を被係止面４７という。この被係止面４７は、係止方向Ｌに略直交する面である。   Here, in the main wall portion 46, an end face in front of the locking direction L is referred to as a locked surface 47. The locked surface 47 is a surface substantially orthogonal to the locking direction L.

また、ここでは、被係止部４２は、係止方向Ｌ後方で、補助壁部４４、主壁部４６及び一対の支持片４８の端部が面一となるように形成されている（図４、図５参照）。   Further, here, the locked portion 42 is formed so that the auxiliary wall portion 44, the main wall portion 46, and the ends of the pair of support pieces 48 are flush with each other in the locking direction L (see FIG. 4, see FIG.

係止部５２は、第１本体部２２と第２本体部３２との合体状態で、被係止部４２に対して係止可能に形成されている。この係止部５２は、延出片５４と、係止突部５６とを有している（図３〜図７参照）。   The locking portion 52 is formed so as to be locked to the locked portion 42 in the combined state of the first main body portion 22 and the second main body portion 32. The locking portion 52 has an extending piece 54 and a locking projection 56 (see FIGS. 3 to 7).

延出片５４は、被係止部４２の補助壁部４４と主壁部４６との間に挿入可能に形成されている部分である。より具体的には、延出片５４は、第１本体部２２と第２本体部３２との合体状態で、被係止部４２の補助壁部４４及び主壁部４６と略平行な面に沿って扁平な矩形板状に形成されている。この延出片５４は、第２本体部３２の側端部から係止方向Ｌ前方に向けて延出するように形成されている。ここでは、延出片５４は、第２本体部３２の側壁部の先端部のうち、第１本体部２２と第２本体部３２との合体状態で被係止部４２と対向する位置から延出する。また、延出片５４は、基端部が第２本体部３２の側壁部に重なり、すなわち、当該側壁部の外面から厚さ寸法分盛り上がる形態で設けられ、先端側部分が側壁部の先端部から係止方向Ｌ前方に延出している（図５、図７参照）。   The extending piece 54 is a portion formed so as to be insertable between the auxiliary wall portion 44 and the main wall portion 46 of the locked portion 42. More specifically, the extending piece 54 is formed in a plane substantially parallel to the auxiliary wall portion 44 and the main wall portion 46 of the locked portion 42 in the combined state of the first main body portion 22 and the second main body portion 32. It is formed in a rectangular plate shape that is flat along. The extending piece 54 is formed so as to extend forward from the side end portion of the second main body portion 32 toward the front in the locking direction L. Here, the extending piece 54 extends from a position facing the locked portion 42 in the combined state of the first main body portion 22 and the second main body portion 32 in the front end portion of the side wall portion of the second main body portion 32. Put out. In addition, the extending piece 54 is provided in a form in which the base end portion overlaps the side wall portion of the second main body portion 32, that is, is swelled by the thickness dimension from the outer surface of the side wall portion, and the tip end portion is the tip end portion of the side wall portion. Extends forward in the locking direction L (see FIGS. 5 and 7).

そして、延出片５４が補助壁部４４と主壁部４６との間に挿入されると、第２本体部３２の側端部は、主壁部４６及び一対の支持片４８と略面一に設定されている補助壁部４４の係止方向Ｌ後方端面に当接する（図６、図７参照）。   When the extension piece 54 is inserted between the auxiliary wall portion 44 and the main wall portion 46, the side end portion of the second main body portion 32 is substantially flush with the main wall portion 46 and the pair of support pieces 48. It contacts the rear end surface of the auxiliary wall portion 44 in the locking direction L (see FIGS. 6 and 7).

この延出片５４の延出寸法（第２本体部３２の側端部を越えて延出する寸法）は、係止方向Ｌにおける主壁部４６の寸法より大きく設定されている。すなわち、延出片５４は、補助壁部４４と主壁部４６との間に挿入されて第２本体部３２の側端部が補助壁部４４の端面に当接した状態で、主壁部４６を越えて延出するように形成されている。より具体的には、延出片５４は、主壁部４６より、後述する係止突部５６分大きい延出寸法に設定されている。   The extension dimension of the extension piece 54 (the dimension extending beyond the side end portion of the second main body portion 32) is set larger than the dimension of the main wall portion 46 in the locking direction L. That is, the extension piece 54 is inserted between the auxiliary wall portion 44 and the main wall portion 46, and the side wall portion of the second main body portion 32 is in contact with the end surface of the auxiliary wall portion 44. It is formed to extend beyond 46. More specifically, the extension piece 54 is set to an extension dimension that is larger than the main wall portion 46 by a locking projection 56 described later.

ここでは、延出片５４は、幅方向中間部が両端部より第２本体部３２の外側に膨らむように形成されている（図３参照）。すなわち、延出片５４の外面は、幅方向中間部が外側に凸となる断面視弧状に形成されている。より具体的には、延出片５４の幅方向両端部は補助壁部４４と主壁部４６との間隔と同じかそれより小さい（ここでは僅かに小さい）厚さ寸法に設定され、幅方向中間部は前記間隔と同じかそれより大きい（ここでは僅かに大きい）厚さ寸法に設定されている。これにより、延出片５４は、補助壁部４４と主壁部４６との間に挿入された状態で、補助壁部４４及び主壁部４６に対して押圧しつつ接触し、その間におけるがたつきを抑制することができる。   Here, the extending piece 54 is formed such that the intermediate portion in the width direction swells to the outside of the second main body portion 32 from both end portions (see FIG. 3). That is, the outer surface of the extension piece 54 is formed in a cross-sectional arc shape in which the intermediate portion in the width direction is convex outward. More specifically, both end portions in the width direction of the extending piece 54 are set to have a thickness dimension that is the same as or smaller than the interval between the auxiliary wall portion 44 and the main wall portion 46 (slightly smaller here), and the width direction The intermediate portion is set to a thickness dimension equal to or larger than the interval (slightly larger here). As a result, the extension piece 54 is pressed between the auxiliary wall portion 44 and the main wall portion 46 in a state of being inserted between the auxiliary wall portion 44 and the main wall portion 46, and rattle between them. Suppression can be suppressed.

また、延出片５４の幅寸法は、主壁部４６を支持する一対の支持片４８の間隔より小さく設定されている。   Further, the width dimension of the extending piece 54 is set smaller than the distance between the pair of supporting pieces 48 that support the main wall portion 46.

もっとも、延出片５４は、上記形状に限られるものではなく、例えば、第２本体部３２の側壁部から直線状に延びるように形成されていてもよい。すなわち、延出片５４は、基端部が第２本体部３２の側壁部に重なるように設けられていなくてもよい。また、延出片５４は、幅方向中間部と両端部とで均一な厚さに設定されていてもよい。   However, the extending piece 54 is not limited to the shape described above, and may be formed to extend linearly from the side wall portion of the second main body portion 32, for example. That is, the extension piece 54 may not be provided so that the base end portion overlaps the side wall portion of the second main body portion 32. Further, the extending piece 54 may be set to a uniform thickness at the intermediate portion in the width direction and at both ends.

係止突部５６は、被係止部４２に対して係止方向Ｌに近接させることにより（実質的に）係止する部分である。この係止突部５６は、延出片５４の先端側部分から当該延出片５４の延出方向と略直交する方向に向けて突出するように形成されている部分である（図５、図７参照）。ここでは、係止突部５６の突出方向は、第２本体部３２の側壁部の外方に向かう方向に設定されている。   The locking projection 56 is a portion that is locked (substantially) by being brought close to the locked portion 42 in the locking direction L. The locking projection 56 is a portion formed so as to protrude from the distal end side portion of the extending piece 54 in a direction substantially perpendicular to the extending direction of the extending piece 54 (FIGS. 5 and 5). 7). Here, the protruding direction of the locking protrusion 56 is set in a direction toward the outside of the side wall portion of the second main body portion 32.

また、この係止突部５６は、延出片５４のうち、延出片５４が補助壁部４４と主壁部４６との間に完全に挿入された状態で、主壁部４６の係止方向Ｌ前方に位置する部分に形成されている（図６、図７参照）。   In addition, the locking protrusion 56 locks the main wall portion 46 in a state where the extended piece 54 of the extended piece 54 is completely inserted between the auxiliary wall portion 44 and the main wall portion 46. It is formed in a portion located in the front in the direction L (see FIGS. 6 and 7).

より具体的には、係止突部５６は、延出片５４の先端側から基端側に向けて徐々に突出寸法が大きくなる部分とその基端部から一定の突出寸法で基端側に向かう部分とを有する形状に形成されている（図５、図７参照）。すなわち、この係止突部５６は、断面視台形状に形成されている。ここで、係止突部５６の基端面を係止面５７といい、この係止面５７は、係止方向Ｌ後方に向かう面である。   More specifically, the locking projection 56 has a portion in which the projecting dimension gradually increases from the distal end side to the proximal end side of the extending piece 54 and a proximal projecting dimension from the proximal end portion to the proximal end side. It is formed in a shape having a portion facing (see FIGS. 5 and 7). That is, the locking projection 56 is formed in a trapezoidal shape in cross section. Here, the base end surface of the locking projection 56 is referred to as a locking surface 57, and the locking surface 57 is a surface facing the locking direction L.

そして、延出片５４を補助壁部４４と主壁部４６との間に挿入すると、係止突部５６の先端側の傾斜面が主壁部４６に当接して、当該主壁部４６を補助壁部４４から離間させる向きに弾性変形させていく。係止突部５６が主壁部４６を乗り越える位置まで延出片５４が挿入されると、主壁部４６が弾性復帰して被係止面４７と係止面５７とが対向して当接し、係止部５２が被係止部４２に対して係止する（図７参照）。   When the extending piece 54 is inserted between the auxiliary wall portion 44 and the main wall portion 46, the inclined surface on the distal end side of the locking projection 56 abuts on the main wall portion 46, and the main wall portion 46 is Elastic deformation is performed in a direction away from the auxiliary wall portion 44. When the extending piece 54 is inserted to a position where the locking projection 56 gets over the main wall 46, the main wall 46 is elastically restored and the locked surface 47 and the locking surface 57 are opposed to each other. The locking part 52 is locked to the locked part 42 (see FIG. 7).

なお、被係止部４２の補助壁部４４は、係止突部５６が主壁部４６に係止した状態で、延出片５４が第１本体部２２の内側に移動するのを規制するように、係止方向Ｌにおいて当該延出片５４の内側部全体に当接可能な寸法に設定されているとよい。これにより、係止突部５６が主壁部４６に係止した状態をより確実に維持することができる。   The auxiliary wall portion 44 of the locked portion 42 restricts the extension piece 54 from moving to the inside of the first main body portion 22 in a state where the locking projection 56 is locked to the main wall portion 46. Thus, it is good to set it as the dimension which can contact | abut to the whole inner side part of the said extension piece 54 in the latching direction L. FIG. Thereby, the state which the latching protrusion 56 latched to the main wall part 46 can be maintained more reliably.

もっとも、係止突部５６は、主壁部４６の係止方向Ｌ前方端面に係止可能であればよく、上記形状の他にも、断面視半球状等の凸形状であってもよい。   But the latching protrusion 56 should just be latchable in the latching direction L front end surface of the main wall part 46, and may be convex shapes, such as a cross-sectional hemisphere other than the said shape.

上述したロック構造部４０は、第１本体部２２と第２本体部３２とを合体状態に維持することができればよく、上記形状に限られるものではない。例えば、主壁部のうち補助壁部４４側の面で開口する凹部又は孔部が形成され、係止部が当該凹部又は孔部に嵌合可能な凸状の係止突部を有している構成であってもよい。また、被係止部が第１本体部２２の側壁部に形成された凹部又は孔部であり、係止部が第２本体部３２の内側に向けて突出する係止突部を有し、第１本体部２２と第２本体部３２との合体状態で、係止突部が当該凹部又は孔部内に進入して係止するように構成されていてもよい。この場合にも、第１本体部２２の側壁部に対して間隔をあけた壁部が設けられてもよい。   The lock structure 40 described above is not limited to the above-described shape as long as the first main body 22 and the second main body 32 can be maintained in the combined state. For example, a recess or a hole that opens on the auxiliary wall 44 side surface of the main wall is formed, and the locking portion has a convex locking protrusion that can be fitted into the recess or the hole. It may be a configuration. Further, the locked portion is a recess or hole formed in the side wall portion of the first main body portion 22, and the locking portion has a locking protrusion protruding toward the inside of the second main body portion 32, In the combined state of the first main body portion 22 and the second main body portion 32, the locking protrusion may be configured to enter and lock into the recess or hole. Also in this case, a wall part spaced from the side wall part of the first main body part 22 may be provided.

すなわち、上記変形例に係るロック構造部の場合にも、係止状態で当接する面が係止部の係止面及び被係止部の被係止面である。   That is, also in the case of the lock structure portion according to the above modification, the surfaces that come into contact in the locked state are the locking surface of the locking portion and the locked surface of the locked portion.

また、ロック構造部４０について、係止突部５６が延出片５４の先端側部分に設けられている係止部５２を有する例で説明したが、延出片５４が省略され、係止突部が第２本体部３２の側端部から外方に突出するように設けられていてもよい。この場合、被係止部の主壁部４６は、係止方向Ｌ前方側端部のうちの幅方向両端部が一対の支持片に支持されるように形成されていればよい。すなわち、補助壁部４４と主壁部４６との間に第２本体部３２の側壁部の先端側部分を挿入可能に形成されているとよい。   Further, the lock structure portion 40 has been described with an example in which the locking protrusion 56 has the locking portion 52 provided at the tip side portion of the extending piece 54, but the extending piece 54 is omitted, and the locking protrusion The portion may be provided so as to protrude outward from the side end portion of the second main body portion 32. In this case, the main wall portion 46 of the locked portion only needs to be formed such that both ends in the width direction of the front end portion in the locking direction L are supported by the pair of support pieces. That is, it is preferable that the distal end portion of the side wall portion of the second main body portion 32 be formed between the auxiliary wall portion 44 and the main wall portion 46 so as to be insertable.

また、被係止部４２及び係止部５２が、第１本体部２２及び第２本体部３２の合体時に突き合わされる各側端部に形成されている例で説明してきたが、第１本体部２２と第２本体部３２とが各側壁部を内外に重ねて合体されるような形態である場合等には、一方の側端部に係止部５２を設け、他方の側壁部の対応する箇所に被係止部４２を設けるとよい。すなわち、被係止部４２及び係止部５２は、第１本体部２２及び第２本体部３２の合体状態で係止する位置に形成されていればよい。さらに、第１本体部２２及び第２本体部３２が断面視Ｕ字形の凹状部材とは異なる上記例示した形状等の場合でも、第１本体部２２及び第２本体部３２の適宜箇所に被係止部４２及び係止部５２が設けられればよい。   Moreover, although the to-be-latched part 42 and the latching | locking part 52 were demonstrated in the example currently formed in each side edge part faced at the time of the unification | combination of the 1st main-body part 22 and the 2nd main-body part 32, the 1st main body In the case where the portion 22 and the second main body portion 32 are combined with each other by overlapping the side wall portions inside and outside, a locking portion 52 is provided at one side end portion, and the other side wall portion is supported. It is good to provide the to-be-latched part 42 in the location to do. That is, the to-be-latched part 42 and the latching | locking part 52 should just be formed in the position latched in the united state of the 1st main-body part 22 and the 2nd main-body part 32. FIG. Further, even when the first main body portion 22 and the second main body portion 32 have the above-described shape and the like different from the U-shaped concave member in cross-section, the first main body portion 22 and the second main body portion 32 are engaged at appropriate positions. The stop part 42 and the latching | locking part 52 should just be provided.

上記ロック構造部４０は、本体部２０の外周部に複数設けられているとよい。後述する押圧部６０及び補強リブ７０についても同様である。   A plurality of the lock structure portions 40 may be provided on the outer peripheral portion of the main body portion 20. The same applies to a pressing portion 60 and a reinforcing rib 70 described later.

上述したように、係止部５２は、延出片５４が第２本体部３２の外面から盛り上がるように形成されているものの、当該延出片５４の基端部の厚さ寸法（盛り上がり寸法）は小さく押圧することが困難であり、たとえ押圧できたとしても力を作用させ難い。また、係止部５２が設けられた第２本体部３２の側壁部の基端部（板状の基部の側端部）を押圧することも可能であるが、当該押圧力が、係止部５２が被係止部４２に対して係止する際に係止方向Ｌと異なる方向（例えば側壁部の内外方向）にも分散して作用し、側壁部が撓んでしまう恐れがあった。特に、側壁部の突出寸法が大きい場合、又は、材料軽減及び軽量化の観点から薄肉化されている場合には、その影響は顕著に現れると推測される。このように側壁部の撓みが発生すると、被係止部４２に係止する係止部５２に対して係止方向Ｌの力を伝え難く、第１本体部２２と第２本体部３２との合体作業の作業性が低下する恐れがあった。   As described above, the locking portion 52 is formed so that the extended piece 54 swells from the outer surface of the second main body portion 32, but the thickness dimension (swelled dimension) of the proximal end portion of the extended piece 54 is concerned. Is difficult to press, and even if it can be pressed, it is difficult to apply force. Moreover, although it is possible to press the base end part (the side end part of a plate-like base part) of the side wall part of the 2nd main-body part 32 in which the latching | locking part 52 was provided, the said pressing force is a latching part. When 52 is locked to the locked portion 42, it acts in a distributed manner in a direction different from the locking direction L (for example, the inner and outer directions of the side wall), and the side wall may be bent. In particular, when the protruding dimension of the side wall is large, or when the side wall is thinned from the viewpoint of material reduction and weight reduction, it is estimated that the influence appears remarkably. When the side wall portion is bent in this manner, it is difficult to transmit the force in the locking direction L to the locking portion 52 locked to the locked portion 42, and the first main body portion 22 and the second main body portion 32 are not connected. The workability of the coalescing work may be reduced.

そこで、本プロテクタ１０では、第１本体部２２と第２本体部３２との合体に伴う係止部５２の被係止部４２に対する係止作業を容易にすると共に、係止部５２に対して係止方向Ｌの力をより効率よく伝えるために押圧部６０を設けている。   Therefore, in the protector 10, the locking operation of the locking portion 52 associated with the combination of the first main body portion 22 and the second main body portion 32 is facilitated, and the locking portion 52 is fixed. In order to transmit the force in the locking direction L more efficiently, the pressing portion 60 is provided.

押圧部６０は、第２本体部３２又は係止部５２（ここでは第２本体部３２）のうち、係止突部５６に対して係止方向Ｌ後方の位置から、係止突部５６の基端部より側方に突出するように形成されている（図２、図３参照）。より具体的には、押圧部６０は、係止方向Ｌに略直交する扁平な板状に形成され、係止方向Ｌに略直交する押圧面６２を有している（図４〜図７参照）。   The pressing portion 60 is configured to move the locking projection 56 from the position behind the locking projection 56 in the locking direction 56 of the second main body 32 or the locking portion 52 (here, the second main body 32). It is formed so as to protrude from the base end side (see FIGS. 2 and 3). More specifically, the pressing portion 60 is formed in a flat plate shape substantially orthogonal to the locking direction L, and has a pressing surface 62 substantially orthogonal to the locking direction L (see FIGS. 4 to 7). ).

この押圧部６０の押圧面６２は、平面視略矩形に形成され、作業者が押圧しやすい大きさに設定されている。以下、押圧部６０の突出寸法及び幅寸法について説明する。   The pressing surface 62 of the pressing portion 60 is formed in a substantially rectangular shape in plan view, and is set to a size that is easy for an operator to press. Hereinafter, the protrusion dimension and the width dimension of the pressing part 60 will be described.

押圧部６０は、第２本体部３２の外面から、第２本体部３２の外面から厚さ寸法分盛り上がるように設けられている延出片５４の厚さ寸法（盛り上がり寸法）より大きく突出するように形成されている。例えば、延出片５４の厚さ寸法が１．５ｍｍである場合、押圧部６０は、少なくとも１．５ｍｍより大きい突出寸法に設定される。好ましくは、押圧部６０は、作業者が指で力を加えやすい程度に突出しているとよい。   The pressing part 60 protrudes from the outer surface of the second main body part 32 to be larger than the thickness dimension (swelling dimension) of the extending piece 54 provided so as to rise from the outer surface of the second main body part 32 by the thickness dimension. Is formed. For example, when the thickness dimension of the extending piece 54 is 1.5 mm, the pressing portion 60 is set to a protruding dimension that is at least larger than 1.5 mm. Preferably, the pressing part 60 may protrude to such an extent that an operator can easily apply force with a finger.

また、押圧部６０の幅寸法は、作業者が押圧する際に使用すると想定される指の先端部の幅と同じかそれより大きい寸法に設定されているとよい。例えば、人差し指で押圧することが多いと想定される場合、平均的な人差し指の先端部の幅より大きくなるように形成すればよい。   Moreover, the width dimension of the press part 60 is good to be set to the same dimension as the width | variety of the front-end | tip part of the finger | toe used when an operator presses, or a dimension larger than it. For example, when it is assumed that the index finger is often pressed, it may be formed so as to be larger than the width of the average tip of the index finger.

押圧部６０は、係止方向Ｌにおいて、第２本体部３２と延出片５４との境界の位置から突出している。ここで、第２本体部３２と延出片５４との境界の位置とは、係止方向Ｌにおいて、押圧部６０の係止方向Ｌ前方端面が延出片５４の基端部と一致する位置から、押圧面６２が第２本体部３２の側壁部の先端部と一致する位置までの範囲を含むものとする。ここでは、第２本体部３２の側壁部の外面のうち、係止方向Ｌにおいて、押圧面６２が係止部５２の延出片５４の基端部と略同じ位置に位置するように設けられている（図２参照）。また、押圧部６０の係止方向Ｌ前方端部は、第２本体部３２の側壁部の先端部の位置と略一致している（図５参照）。このように、押圧部６０は、押圧されたときに第２本体部３２及び延出片５４の撓みがより効果的に抑制されるように、係止部５２の先端部になるべく近い位置に形成されている。   The pressing portion 60 protrudes from the boundary position between the second main body portion 32 and the extending piece 54 in the locking direction L. Here, the position of the boundary between the second main body portion 32 and the extending piece 54 is a position where the front end surface in the locking direction L of the pressing portion 60 coincides with the base end portion of the extending piece 54 in the locking direction L. To the position where the pressing surface 62 coincides with the tip of the side wall portion of the second main body portion 32. Here, of the outer surface of the side wall portion of the second main body portion 32, the pressing surface 62 is provided in the locking direction L so as to be positioned at substantially the same position as the base end portion of the extending piece 54 of the locking portion 52. (See FIG. 2). Further, the front end portion in the locking direction L of the pressing portion 60 substantially coincides with the position of the tip portion of the side wall portion of the second main body portion 32 (see FIG. 5). As described above, the pressing portion 60 is formed at a position as close as possible to the distal end portion of the locking portion 52 so that the bending of the second main body portion 32 and the extending piece 54 is more effectively suppressed when pressed. Has been.

また、上述した係止部５２の係止突部５６は、押圧部６０と同じ向きに突出している。すなわち、係止突部５６は、係止方向Ｌに略直交する向きに突出し、係止方向Ｌにおいて係止面５７が押圧部６０と対向するように形成されている。   Further, the locking protrusion 56 of the locking portion 52 described above protrudes in the same direction as the pressing portion 60. That is, the locking projection 56 protrudes in a direction substantially orthogonal to the locking direction L, and the locking surface 57 is formed to face the pressing portion 60 in the locking direction L.

そして、上記押圧部６０の係止方向Ｌ前方端部の位置は、係止突部５６の係止面５７が主壁部４６の被係止面４７に係止した状態で、主壁部の係止方向Ｌ後方端部に当接可能な位置である（図６、図７参照）。換言すると、押圧部６０は、係止突部５６の係止面５７に対して、主壁部４６の係止方向Ｌにおける寸法と略同じ（ここでは僅かに大きい）間隔をあけた位置に形成されている。これにより、係止部５２が被係止部４２に係止した状態では、主壁部４６は、係止突部５６と押圧部６０との間に挟まれた状態となる。   The position of the front end portion in the locking direction L of the pressing portion 60 is such that the locking surface 57 of the locking projection 56 is locked to the locked surface 47 of the main wall portion 46. It is a position that can contact the rear end of the locking direction L (see FIGS. 6 and 7). In other words, the pressing portion 60 is formed at a position that is spaced apart from the locking surface 57 of the locking projection 56 by substantially the same (slightly larger in this case) interval as the dimension of the main wall portion 46 in the locking direction L. Has been. Thereby, in a state where the locking portion 52 is locked to the locked portion 42, the main wall portion 46 is sandwiched between the locking protrusion 56 and the pressing portion 60.

もっとも、係止突部５６と押圧部６０との間に主壁部４６が挟まれる形態に限られず、係止突部５６の係止面５７が主壁部４６の被係止面４７に当接した状態で、押圧部６０の係止方向Ｌ前方端面が主壁部４６の係止方向Ｌ後方端面に当接（少なくとも近接して対向）していればよい。すなわち、押圧部６０及び係止突部５６が主壁部４６に対して上記位置関係となることにより、被係止部４２と係止部５２との係止方向Ｌ両側における相対移動を規制できればよい。例えば、上述したロック構造部の変形例の場合にも、この位置関係が成り立っているとよい。   However, the main wall 46 is not limited to be sandwiched between the locking projection 56 and the pressing portion 60, and the locking surface 57 of the locking projection 56 contacts the locked surface 47 of the main wall 46. It is only necessary that the front end surface in the locking direction L of the pressing portion 60 is in contact (at least in close proximity to) the rear end surface in the locking direction L of the main wall portion 46 in contact. In other words, if the pressing portion 60 and the locking protrusion 56 are in the above-described positional relationship with respect to the main wall portion 46, the relative movement of the locked portion 42 and the locking portion 52 on both sides in the locking direction L can be restricted. Good. For example, this positional relationship may be satisfied in the case of the above-described modification of the lock structure.

上記押圧部６０は、押圧時の撓みを抑制するため、第１本体部２２及び第２本体部３２の壁部より肉厚に形成されていてもよい。また、押圧部６０は、外周部が内周側部分よりも肉厚に形成されていてもよい。   The pressing portion 60 may be formed thicker than the wall portions of the first main body portion 22 and the second main body portion 32 in order to suppress bending during pressing. Moreover, as for the press part 60, the outer peripheral part may be formed thicker than the inner peripheral side part.

また、押圧部６０は、上述した位置に設けられる場合に限られず、第２本体部３２の側壁部の基端部を押圧する場合より当該第２本体部の撓みを小さくするという観点からは、少なくとも当該側壁部の基端部より係止方向Ｌ前方側の位置に設けられていればよい。好ましくは、押圧部６０は、なるべく係止突部５６に近い位置に設けられるとよく、係止部５２の延出片５４に設けられてもよい。もっとも、押圧部６０が設けられる位置は、ロック構造部４０の係止動作の邪魔にならない位置であることが前提である。   In addition, the pressing part 60 is not limited to the case where it is provided at the above-described position, but from the viewpoint of reducing the bending of the second main body part as compared with the case where the base end part of the side wall part of the second main body part 32 is pressed. It suffices to be provided at least at a position on the front side in the locking direction L from the base end portion of the side wall portion. Preferably, the pressing portion 60 may be provided at a position as close to the locking projection 56 as possible, and may be provided on the extended piece 54 of the locking portion 52. However, it is assumed that the position where the pressing portion 60 is provided is a position that does not interfere with the locking operation of the lock structure portion 40.

補強リブ７０は、押圧部６０の押圧面６２のうち少なくとも一部を、第２本体部３２の外面に対して連結する部分である（図２参照）。より具体的には、補強リブ７０は、側面視略直角三角形の筋状に形成され、直角部分を挟む２辺がそれぞれ押圧部６０と第２本体部３２の側壁部の外面とに対して連結されている。これにより、押圧部６０と第２本体部３２との延在面の相対角度が変化することが抑制される。   The reinforcing rib 70 is a part that connects at least a part of the pressing surface 62 of the pressing part 60 to the outer surface of the second main body part 32 (see FIG. 2). More specifically, the reinforcing rib 70 is formed in the shape of a substantially right triangle when viewed from the side, and two sides sandwiching the right angle portion are connected to the pressing portion 60 and the outer surface of the side wall portion of the second main body portion 32, respectively. Has been. Thereby, it is suppressed that the relative angle of the extension surface of the press part 60 and the 2nd main-body part 32 changes.

ここでは、補強リブ７０は、押圧部６０の一側端部のみに設けられている。本実施形態におけるプロテクタ１０は、図２に示すように、第２本体部３２のうち押圧部６０の他側方には、外方に向けて突出する部分が設けられており、押圧部６０の他側端部が当該外方に向けて突出する部分に固定されている。すなわち、押圧部６０の他側端部は、補強リブ７０に支持されている一側端部と同様に、第２本体部３２の側壁部の外面と連結されている。   Here, the reinforcing rib 70 is provided only at one end portion of the pressing portion 60. As shown in FIG. 2, the protector 10 according to the present embodiment is provided with a portion projecting outward on the other side of the pressing portion 60 in the second main body portion 32. The other side end is fixed to a portion protruding outward. That is, the other end portion of the pressing portion 60 is connected to the outer surface of the side wall portion of the second main body portion 32 in the same manner as the one end portion supported by the reinforcing rib 70.

また、ここでは、補強リブ７０は、押圧部６０の突出方向において、その突出寸法より小さくその半分の寸法より大きい範囲で、第２本体部３２の側壁部の外面に対して押圧部６０を連結している。なお、押圧部６０の撓みを抑制する観点からは、補強リブ７０は、突出方向全体に亘って押圧部６０を支持する形状が好ましい。なお、第２本体部３２の側壁部の外面に対する連結部分も、係止方向Ｌにおいてより大きい範囲で連結されているとよい。一方、補強リブ７０は、押圧部６０を押圧する観点から、押圧の妨げにならないことも考慮してその連結形態が決定されるとよい。   Further, here, the reinforcing rib 70 connects the pressing portion 60 to the outer surface of the side wall portion of the second main body portion 32 in a protruding direction of the pressing portion 60 within a range smaller than the protruding dimension and larger than half the dimension thereof. doing. In addition, from the viewpoint of suppressing the bending of the pressing portion 60, the reinforcing rib 70 preferably has a shape that supports the pressing portion 60 over the entire protruding direction. In addition, it is good also for the connection part with respect to the outer surface of the side wall part of the 2nd main-body part 32 to be connected in the larger range in the latching direction L. FIG. On the other hand, from the viewpoint of pressing the pressing portion 60, the reinforcing rib 70 may be determined in a connection form in consideration of not obstructing the pressing.

上記補強リブ７０は、側面視直角三角形の筋状に限られず、峰部分が側面視弧状（凹凸どちらでもよい）又は側面視略矩形等の筋状に形成されていてもよい。また、押圧部６０は、一対の補強リブ７０により第２本体部３２の外面と連結されていてもよいし、一側端部だけが補強リブ７０により第２本体部３２の外面と連結され、他側端部が自由端となっていてもよい。さらに、補強リブ７０は、押圧部６０の幅方向中間部を支持するように設けられてもよいし、省略されてもよい。   The reinforcing ribs 70 are not limited to the shape of a right-angled triangle when viewed from the side, and the peak portion may be formed in a shape such as a side-viewed arc shape (which may be uneven) or a substantially rectangular shape when viewed from the side. Further, the pressing portion 60 may be connected to the outer surface of the second main body portion 32 by a pair of reinforcing ribs 70, or only one side end portion is connected to the outer surface of the second main body portion 32 by the reinforcing rib 70, The other side end may be a free end. Further, the reinforcing rib 70 may be provided to support the intermediate portion in the width direction of the pressing portion 60 or may be omitted.

本プロテクタ１０は、射出成型、すなわち、溶融した合成樹脂材料を成型金型間に流し込んで冷却することにより形成されるとよい。より具体的には、第１本体部２２及び被係止部４２を一部材として射出成型すると共に、第２本体部３２、係止部５２、押圧部６０及び補強リブ７０を一部材として射出成型すればよい。なお、第１本体部２２と第２本体部３２とがヒンジで連結される構成の場合、上記のように二部材を形成してからヒンジ部材で連結してもよいし、上記二部材を連結するヒンジ部分を有する一部材として射出成型することにより製造することもできる。   The protector 10 may be formed by injection molding, that is, by pouring a molten synthetic resin material between molding dies and cooling. More specifically, the first main body portion 22 and the locked portion 42 are injection molded as one member, and the second main body portion 32, the locking portion 52, the pressing portion 60, and the reinforcing rib 70 are injection molded as one member. do it. In the case where the first main body 22 and the second main body 32 are connected by a hinge, the two members may be formed as described above and then connected by the hinge member, or the two members may be connected. It can also be manufactured by injection molding as one member having a hinge portion.

また、プロテクタ１０は、上記構成に限定されるものではなく、第１本体部２２に係止部が設けられ、第２本体部３２に被係止部が設けられても良いし、第１本体部２２及び第２本体部３２の一方に係止部及び被係止部がそれぞれ設けられ、これに対応するように他方に被係止部及び係止部が設けられていてもよい。   The protector 10 is not limited to the above configuration, and the first main body 22 may be provided with a locking portion, and the second main body 32 may be provided with a locked portion. The locking part and the locked part may be provided on one of the part 22 and the second main body part 32, respectively, and the locked part and the locking part may be provided on the other to correspond to this.

上記構成に係るプロテクタ１０によると、押圧部６０が、第２本体部３２のうち係止突部５６に対して係止方向Ｌ後方の位置から、係止突部５６の基端部より側方に突出するように形成されている。このため、第１本体部２２と第２本体部３２とを合体させる際に、押圧部６０を押圧することにより、係止部５２の基端部を押圧する場合と比較して押圧しやすく、係止方向Ｌに力を作用させやすい。また、押圧部６０が、係止方向Ｌにおいて、第２本体部３２と延出片５４との境界の位置から突出するように形成されているため、より係止突部５６に近い位置で力を作用させることができ、力を加える位置と係止部５２との距離が大きい場合と比較して、係止部５２を被係止部４２に係止させる際に、力が係止方向Ｌと異なる方向に分散することを抑制でき、第２本体部３２の側壁部が撓むことを抑制することができる。これにより、プロテクタ１０の組立作業性を向上させることができる。   According to the protector 10 according to the above-described configuration, the pressing portion 60 is lateral to the locking projection 56 from the position behind the locking projection 56 in the second body 32 from the base end of the locking projection 56. It is formed so as to protrude. For this reason, when uniting the 1st main part 22 and the 2nd main part 32, it is easy to press compared with the case where the base end part of locking part 52 is pressed by pressing press part 60, It is easy to apply a force in the locking direction L. Further, since the pressing portion 60 is formed so as to protrude from the position of the boundary between the second main body portion 32 and the extending piece 54 in the locking direction L, the force is closer to the locking projection 56. Compared with the case where the distance between the position where the force is applied and the locking portion 52 is large, the force is increased in the locking direction L when the locking portion 52 is locked to the locked portion 42. It can suppress that it distributes in a different direction, and can suppress that the side wall part of the 2nd main-body part 32 bends. Thereby, the assembly workability | operativity of the protector 10 can be improved.

また、作業者が押圧部６０を直接押すことができるため、治具等を用いなくても容易に係止部５２を被係止部４２に係止させることができる。   Further, since the operator can directly press the pressing portion 60, the locking portion 52 can be easily locked to the locked portion 42 without using a jig or the like.

また、押圧部６０が、第１本体部２２と第２本体部３２との合体方向と同方向に設定された係止部５２の係止方向Ｌに直交する押圧面６２を有しているため、係止方向Ｌに力を作用させやすい。そして、第１本体部２２と第２本体部３２とを合体させる一連の動作として、押圧部６０を押圧して係止部５２を被係止部４２に係止させることができる。   Moreover, since the pressing part 60 has the pressing surface 62 orthogonal to the latching direction L of the latching | locking part 52 set to the same direction as the unification direction of the 1st main-body part 22 and the 2nd main-body part 32. It is easy to apply a force in the locking direction L. And as a series of operation | movement which unites the 1st main-body part 22 and the 2nd main-body part 32, the press part 60 can be pressed and the latching | locking part 52 can be latched by the to-be-latched part 42. FIG.

また、補強リブ７０が、扁平形状に形成されている押圧部６０の押圧面６２の一側端部と第２本体部３２の外面とを連結するように形成されているため、押圧部６０を押圧する際に押圧部６０が撓むことを抑制できる。また、第２本体部３２の側壁部の強度を上げて、その撓みを抑制することもできる。   Further, since the reinforcing rib 70 is formed so as to connect one end portion of the pressing surface 62 of the pressing portion 60 formed in a flat shape and the outer surface of the second main body portion 32, the pressing portion 60 is It can suppress that the press part 60 bends, when pressing. Further, the strength of the side wall portion of the second main body portion 32 can be increased to suppress the bending thereof.

また、押圧部６０は、係止突部５６に対して、係止面５７が主壁部４６の被係止面４７に当接して係止部５２が被係止部４２に係止した状態で、主壁部４６の係止方向Ｌ後方端面に当接可能な位置に形成されている。このため、係止部５２が被係止部４２に係止した状態で、係止方向Ｌにおいて、係止突部５６と押圧部６０との間に主壁部４６を挟んだ状態にすることができ、がたつきを抑制してより確実に係止状態を維持することができる。   The pressing portion 60 is in a state in which the locking surface 57 abuts on the locked surface 47 of the main wall 46 with respect to the locking projection 56 and the locking portion 52 is locked to the locked portion 42. Thus, the main wall portion 46 is formed at a position capable of contacting the rear end surface in the locking direction L. For this reason, with the locking portion 52 locked to the locked portion 42, the main wall portion 46 is sandwiched between the locking protrusion 56 and the pressing portion 60 in the locking direction L. It is possible to maintain the locked state more reliably by suppressing rattling.
