The insertion head that is erected upward from a side edge facing each elastic locking claw of the insertion portion with a width narrower than the width between the locking projections of each elastic locking claw, and is inserted into the insertion portion A U-shaped cover portion that covers the portion, and a base of the both side surface portions from a position facing the lower side by a predetermined height from the distal end portion of the insertion head that is inserted into the insertion portion of the both side surface portions of the cover portion. An outer member having a pair of cutout portions that are notched to the end and are drilled so that the locking projections of the elastic locking claws protrude outward. Is inserted, the insertion head is inserted into the insertion portion of the outer member, and the base portion is inserted into the flat plate. When the pair of notches are in contact with each other, the upper edge portions of the pair of notches are in contact with the outer surfaces of the pair of elastic locking claws away from each other to act as the pair of contacts, and the pair of notches The elastic locking claw is elastically locked in the locking hole.

更に、請求項３に係るクリップは、請求項２に記載のクリップにおいて、前記嵌入頭部は、先端部の前記左右両側に直交する方向の両端部から該直交する方向外側に突出される一対の抜け止め部を有し、前記アウター部材は、前記挿通部の前記各抜け止め部に対向する両側縁から該各抜け止め部よりも低い高さで立設されると共に、各先端部から挿通部側方向に前記嵌入頭部の側面部よりも内側まで突設される突出部が形成された外側方向に弾性変形可能な一対の係止片を有し、前記係止孔に前記アウター部材を挿通後、該アウター部材の挿通部に前記嵌入頭部を挿通して前記各抜け止め部を前記各係止片よりも上側まで挿通した場合には、前記突出部が該嵌入頭部の各側面部に当接して該各係止片が該係止孔の外側方向に弾性変形して該係止孔に弾性的に係止されると共に、前記一対の弾性係止爪が該係止孔に弾性的に係止されることを特徴とする。   Furthermore, the clip according to claim 3 is the clip according to claim 2, wherein the insertion head is protruded outward in the orthogonal direction from both end portions of the tip portion in the direction orthogonal to the left and right sides. The outer member has a retaining portion, and the outer member is erected at a height lower than the retaining portions from both side edges of the inserting portion facing the retaining portions, and is inserted from the distal end portions. It has a pair of locking pieces that can be elastically deformed in the outward direction and formed with a protruding portion that protrudes inward from the side surface portion of the insertion head in the lateral direction, and the outer member is inserted through the locking hole Thereafter, when the insertion head portion is inserted through the insertion portion of the outer member and the retaining portions are inserted to the upper side of the locking pieces, the protruding portions are the side portions of the insertion head portion. The engaging pieces are elastically deformed in the outward direction of the engaging holes. Together are elastically locked to the hole, the pair of elastic locking pawl, characterized in that the elastically locked to the locking hole.

前記構成を有する請求項１に係るクリップでは、嵌入頭部と一対の当接部とを被取付部材に穿設される係止孔に挿入して、一対の弾性係止爪の係止突起がこの係止孔に弾性的に係止された場合には、一対の当接部が各弾性係止爪の互いに遠ざかる方向の各外側面に嵌入頭部の先端部から所定高さ下側の位置で当接することとなる。
これにより、一対の弾性係止爪の係止突起が被取付部材の係止孔に係止された状態で、大きな引張力が負荷された場合には、各弾性係止爪の嵌入頭部の先端部から所定高さ下側の位置に当接部が当接するため、各弾性係止爪の外側方向への曲げモーメントの支点は、各当接部が当接する位置になって、各係止突起から曲げモーメントの支点までの距離が短くなる。このため、引張力によって各弾性係止爪に発生する曲げモーメントが小さくなり、大きな引張力に耐えることが可能となる。 In the clip according to claim 1 having the above configuration, the fitting head and the pair of abutting portions are inserted into the locking holes formed in the attached member, and the locking protrusions of the pair of elastic locking claws are formed. When elastically locked in this locking hole, the pair of abutment portions are positioned on the respective outer side surfaces of the respective elastic locking claws away from each other at a predetermined height below the tip of the head. Will abut.
Thus, when a large tensile force is applied in a state where the locking projections of the pair of elastic locking claws are locked in the locking holes of the attached member, the insertion heads of the elastic locking claws are inserted. Since the abutting portion comes into contact with the position below the predetermined height from the tip, the fulcrum of the bending moment in the outward direction of each elastic locking claw becomes the position where each abutting portion comes into contact. The distance from the protrusion to the fulcrum of the bending moment is shortened. For this reason, the bending moment which generate | occur | produces in each elastic latching claw by tensile force becomes small, and it becomes possible to endure big tensile force.

また、請求項２に係るクリップでは、被取付部材に穿設される係止孔にアウター部材を挿通後、該アウター部材の挿通部に嵌入頭部を挿通して、基台部をアウター部材の平板部に当接させた場合には、アウター部材のカバー部の両側面部に穿設された一対の切欠部の上端縁部が、一対の弾性係止爪の互いに遠ざかる方向の各外側面に当接して一対の当接部として作用すると共に、一対の弾性係止爪が該係止孔に弾性的に係止される。
これにより、一対の弾性係止爪の係止突起が被取付部材の係止孔に係止された状態で、大きな引張力が負荷された場合には、各弾性係止爪の嵌入頭部の先端部から所定高さ下側の位置に、アウター部材のカバー部の両側面部に穿設された一対の切欠部の上端縁部が当接するため、各弾性係止爪の外側方向への曲げモーメントの支点は、各切欠部の上端縁部が当接する位置になって、各係止突起から曲げモーメントの支点までの距離が短くなる。このため、引張力によって各弾性係止爪に発生する曲げモーメントが小さくなり、大きな引張力に耐えることが可能となる。また、アウター部材を被取付部材の係止孔に挿通後、嵌入頭部をアウター部材の挿通部に挿通することによって、係止孔に各弾性係止爪を係止できるため、クリップを容易に被取付部材の係止孔に取り付けることが可能となる。 Further, in the clip according to claim 2, after the outer member is inserted into the locking hole formed in the attached member, the insertion head is inserted into the insertion portion of the outer member, and the base portion is inserted into the outer member. When abutting against the flat plate portion, the upper edge portions of the pair of notches formed in both side surfaces of the cover portion of the outer member abut against the outer surfaces of the pair of elastic locking claws away from each other. The pair of elastic locking claws are brought into contact with each other and elastically locked in the locking holes.
Thus, when a large tensile force is applied in a state where the locking projections of the pair of elastic locking claws are locked in the locking holes of the attached member, the insertion heads of the elastic locking claws are inserted. Since the upper edge of the pair of notches drilled in the both side surfaces of the cover part of the outer member abuts at a position below a predetermined height from the tip part, the bending moment in the outward direction of each elastic locking claw The fulcrum is the position where the upper edge of each notch contacts, and the distance from each locking projection to the fulcrum of the bending moment is shortened. For this reason, the bending moment which generate | occur | produces in each elastic latching claw by tensile force becomes small, and it becomes possible to endure big tensile force. In addition, after inserting the outer member into the locking hole of the mounted member, each elastic locking claw can be locked in the locking hole by inserting the fitting head into the insertion portion of the outer member, so that the clip can be easily It becomes possible to attach to the locking hole of the member to be attached.

更に、請求項３に係るクリップでは、嵌入頭部の先端部には、一対の弾性係止爪が設けられる左右両側と直交する方向の両端部から該直交する方向外側に一対の抜け止め部が突出している。また、アウター部材は、挿通部の前記各抜け止め部に対向する両側縁から該各抜け止め部よりも低い高さで立設されると共に、各先端部から挿通部側方向に前記嵌入頭部の側面部よりも内側まで突設される突出部が形成された一対の係止片が外側方向に弾性変形可能に設けられている。そして、被取付部材に穿設される係止孔にアウター部材を挿通後、該アウター部材の挿通部に嵌入頭部を挿通して、各抜け止め部を各係止片よりも上側まで挿通した場合には、各係止片の先端部に突設された各突出部が該嵌入頭部の各側面部に当接して該各係止片が該係止孔の外側方向に弾性変形して該係止孔に弾性的に係止されると共に、一対の弾性係止爪が該係止孔に弾性的に係止される。
これにより、大きな引張力が負荷された場合には、各弾性係止爪の嵌入頭部の先端部から所定高さ下側の位置に、アウター部材のカバー部の両側面部に穿設された一対の切欠部の上端縁部が当接するため、引張力によって各弾性係止爪に発生する曲げモーメントが小さくなり、大きな引張力に耐えることが可能となる。また同時に、アウター部材の各係止片が該係止孔の外側方向に弾性変形して係止孔に係止されるため、嵌入頭部の各抜け止め部が該各係止片の突出部の先端部に当接して、更に大きな引張力に耐えることが可能となる。 Further, in the clip according to claim 3, a pair of retaining portions are provided at the distal end portion of the fitting head from both ends in the direction orthogonal to the left and right sides where the pair of elastic locking claws are provided. It protrudes. In addition, the outer member is erected at a height lower than the retaining portions from both side edges of the insertion portion facing the retaining portions, and the insertion heads from the distal end portions toward the inserting portions. A pair of locking pieces formed with projecting portions projecting inwardly from the side surface portions are provided so as to be elastically deformable in the outward direction. And after inserting an outer member in the locking hole drilled in a to-be-attached member, the insertion head was inserted in the insertion part of this outer member, and each retaining part was inserted above each locking piece. In this case, each protrusion protruding from the tip of each locking piece comes into contact with each side surface of the fitting head, and each locking piece is elastically deformed outwardly of the locking hole. While being elastically locked to the locking hole, a pair of elastic locking claws are elastically locked to the locking hole.
Thus, when a large tensile force is applied, a pair of holes formed on both side surfaces of the cover portion of the outer member at a position lower than a predetermined height from the tip of the insertion head of each elastic locking claw. Since the upper edge of the notch portion comes into contact with each other, the bending moment generated in each elastic locking claw by the tensile force is reduced, and it becomes possible to withstand a large tensile force. At the same time, each locking piece of the outer member is elastically deformed outwardly of the locking hole and locked to the locking hole, so that each retaining portion of the fitting head is a protruding portion of each locking piece. It is possible to withstand a larger tensile force by abutting against the tip of each of the members.

図１０に示すように、被取付部材４１には、アウター部材３のカバー部２３の平面視外周形状とほぼ同じ平面視長方形の係止孔４２が穿設されている。そして、先ず、アウター部材３のカバー部２３を係止孔４２に嵌入して被取付部材４１側方向（矢印Ｐ１方向）に押し込み、平板部２２の上面部を被取付部材４１に当接する。続いて、インナー部材２の嵌入頭部７の先端部に形成される各抜け止め部８を、アウター部材３の各係止片２８に対向させつつ、この嵌入頭部７をアウター部材３の挿通部２１に挿通して、アウター部材３方向（矢印Ｐ２方向）に押し込む。かかる押し込む作業は、インナー部材２の嵌入頭部７の先端部に形成される各抜け止め部８が、アウター部材３の各係止片２８を外側方向へ撓ませて、該各係止片２８の上側まで進んで、インナー部材２の基台部５の上面部が、アウター部材３の平板部２２の下面部に当接するまで行われる。   As shown in FIG. 10, a locking hole 42 having a rectangular shape in plan view that is substantially the same as the outer peripheral shape in plan view of the cover portion 23 of the outer member 3 is formed in the attached member 41. First, the cover portion 23 of the outer member 3 is fitted into the locking hole 42 and pushed in the attached member 41 side direction (arrow P1 direction), and the upper surface portion of the flat plate portion 22 is brought into contact with the attached member 41. Subsequently, each retaining portion 8 formed at the tip of the fitting head 7 of the inner member 2 is opposed to each locking piece 28 of the outer member 3, and this fitting head 7 is inserted into the outer member 3. It is inserted through the portion 21 and pushed in the direction of the outer member 3 (arrow P2 direction). In this pushing operation, each retaining portion 8 formed at the tip of the insertion head 7 of the inner member 2 deflects each locking piece 28 of the outer member 3 outwardly, and each locking piece 28 This is performed until the upper surface portion of the base portion 5 of the inner member 2 comes into contact with the lower surface portion of the flat plate portion 22 of the outer member 3.

これにより、図１１乃至図１４に示すように、インナー部材２の各弾性係止爪１１が、係止孔４２の各長辺部に当接されて、内側方向に弾性変形され、各係止突起１２が係止孔４２内に押し込まれる。そして、基台部５の上面部をアウター部材３の平板部２２の下面部に当接させることによって、各弾性係止爪１１が再度、外側方向に弾性変形して、各係止突起１２がアウター部材３の各切欠部２５から外側に突出し、この各係止突起１２の斜め下内側方向に傾斜する各傾斜面が係止孔４２の各長辺部に弾性的に当接して、インナー部材２が係止孔４２に係止される。また、各弾性係止爪１１の上面部が、アウター部材３の内側面に形成された各当接面２６に当接する。   As a result, as shown in FIGS. 11 to 14, the elastic locking claws 11 of the inner member 2 are brought into contact with the long side portions of the locking holes 42 and elastically deformed in the inner direction. The protrusion 12 is pushed into the locking hole 42. And by making the upper surface part of the base part 5 contact | abut to the lower surface part of the flat plate part 22 of the outer member 3, each elastic latching claw 11 is elastically deformed to an outer side again, and each latching protrusion 12 is formed. Each inclined surface that protrudes outward from each notch portion 25 of the outer member 3 and inclines obliquely inwardly and downwardly of each locking projection 12 elastically contacts each long side portion of the locking hole 42, so that the inner member 2 is locked in the locking hole 42. Further, the upper surface portion of each elastic locking claw 11 comes into contact with each contact surface 26 formed on the inner surface of the outer member 3.

また、アウター部材３の各係止片２８の突出部２９の先端部が、インナー部材２の各抜け止め部８の下側の脚部７Ｂに当接して、該各係止片２８が外側方向へ撓み、この各係止片２８の外側面が係止孔４２の各短辺部に当接して、アウター部材３が係止孔４２に係止される。   Further, the distal end portion of the protruding portion 29 of each locking piece 28 of the outer member 3 comes into contact with the lower leg portion 7B of each retaining portion 8 of the inner member 2, and each locking piece 28 is moved outwardly. The outer surface of each locking piece 28 comes into contact with each short side portion of the locking hole 42 and the outer member 3 is locked to the locking hole 42.

従って、本実施例に係るクリップ１では、先ず、アウター部材３のカバー部２３を被取付部材４１の係止孔４２に嵌入して、この被取付部材４１側方向に押し込み、平板部２２の上面部を被取付部材４１に当接する。続いて、インナー部材２の嵌入頭部７の先端部に形成される各抜け止め部８を、アウター部材３の各係止片２８に対向させつつ、この嵌入頭部７をアウター部材３の挿通部２１に挿通して、アウター部材３方向に押し込み、インナー部材２の基台部５の上面部を、アウター部材３の平板部２２の下面部に当接させる。
これにより、アウター部材３の各係止片２８が、外側方向へ撓んで係止孔４２の各短辺部に当接して、該アウター部材３が係止孔４２に係止されると共に、インナー部材２の各弾性係止爪１１の係止突起１２斜め下内側方向に傾斜する各傾斜面が係止孔４２の各長辺部に弾性的に当接して、該インナー部材２が係止孔４２に係止されて、クリップ１を被取付部材４１の係止孔４２に容易に取り付けることが可能となる。 Therefore, in the clip 1 according to the present embodiment, first, the cover portion 23 of the outer member 3 is fitted into the locking hole 42 of the attached member 41 and is pushed in the direction of the attached member 41, and the upper surface of the flat plate portion 22. The part is brought into contact with the attached member 41. Subsequently, each retaining portion 8 formed at the tip of the fitting head 7 of the inner member 2 is opposed to each locking piece 28 of the outer member 3, and this fitting head 7 is inserted into the outer member 3. Inserted into the portion 21 and pushed in the direction of the outer member 3, the upper surface portion of the base portion 5 of the inner member 2 is brought into contact with the lower surface portion of the flat plate portion 22 of the outer member 3.
As a result, each locking piece 28 of the outer member 3 bends outward and comes into contact with each short side portion of the locking hole 42 so that the outer member 3 is locked to the locking hole 42 and the inner member Each inclined surface inclined obliquely downward and inwardly of each elastic locking claw 11 of the member 2 is brought into elastic contact with each long side portion of the locking hole 42 so that the inner member 2 is engaged with the locking hole. The clip 1 can be easily attached to the engaging hole 42 of the member 41 to be attached.

一方、クリップ１が被取付部材４１の係止孔４２に取り付けられた状態で、インナー部材２の基台部５に対して係止孔４２から抜く方向（図１３及び図１４中、下側方向）に引張力が作用した場合には、嵌入頭部７の各抜き止め部８が、アウター部材３の各係止片２８の突出部２９に当接して、各係止片２８が係止孔４２の各短辺部に当接されると共に、各弾性係止爪１１の係止突起１２の斜め下内側方向に傾斜する各傾斜面が係止孔４２の各長辺部に当接することとなる。また、各弾性係止爪１１の嵌入頭部７の先端部から下側の外側面は、アウター部材３のカバー部２３の各切欠部２５の上側の内側面、即ち、各当接面２６に当接される。   On the other hand, in a state in which the clip 1 is attached to the engaging hole 42 of the attached member 41, the direction in which the clip 1 is pulled out from the engaging hole 42 with respect to the base portion 5 of the inner member 2 (the lower direction in FIGS. 13 and 14). ) When a pulling force is applied, each retaining portion 8 of the fitting head 7 comes into contact with the protruding portion 29 of each retaining piece 28 of the outer member 3, and each retaining piece 28 is retained in the retaining hole. Each sloping surface that is in contact with each short side portion of 42 and slanted inward and downward of the locking projection 12 of each elastic locking claw 11 is in contact with each long side portion of the locking hole 42. Become. Further, the lower outer surface from the front end portion of the insertion head 7 of each elastic locking claw 11 is on the upper inner surface of each notch portion 25 of the cover portion 23 of the outer member 3, that is, each contact surface 26. Abutted.

これにより、基台部５に作用する引張力によって、インナー部材２の各弾性係止爪１１に作用する外側方向への曲げモーメントの支点は、各切欠部２５の上端縁部が当接する位置になって、各係止突起１２から曲げモーメントの支点までの距離が短くなる。このため、引張力によって各弾性係止爪１１に発生する曲げモーメントが小さくなり、大きな引張力に耐えることが可能となる。また同時に、アウター部材３の各係止片２８が、係止孔４２の各短辺部の外側方向に弾性変形して該係止孔４２に係止されるため、嵌入頭部７の各抜け止め部８が該各係止片２８の突出部２９の先端部に当接して、更に大きな引張力に耐えることが可能となる。   Accordingly, the fulcrum of the bending moment in the outward direction acting on each elastic locking claw 11 of the inner member 2 by the tensile force acting on the base portion 5 is located at a position where the upper edge of each notch portion 25 abuts. Thus, the distance from each locking projection 12 to the fulcrum of the bending moment is shortened. For this reason, the bending moment which generate | occur | produces in each elastic latching claw 11 by tensile force becomes small, and it becomes possible to endure big tensile force. At the same time, each locking piece 28 of the outer member 3 is elastically deformed in the outward direction of each short side portion of the locking hole 42 and locked to the locking hole 42. The stop portion 8 comes into contact with the tip end portion of the protruding portion 29 of each locking piece 28 and can withstand a greater tensile force.
