Description

本発明は、取付部材の取付孔に挿入して取り付けるための留め具に関する。 The present invention relates to a fastener for inserting and attaching to an attachment hole of an attachment member.

車両には様々な部品を車体パネルに留めるために留め具が用いられる。たとえば特許文献１には、止め具主体とピン部材から構成される止め具が開示される。止め具主体は、板状の鍔と、鍔の中央に形成された挿通孔と、鍔から垂下して対向する２つの脚片を有する。 Vehicles use fasteners to fasten various parts to the vehicle body panel. For example, Patent Document 1 discloses a stopper composed of a stopper main body and a pin member. The stopper main body has a plate-shaped ridge, an insertion hole formed in the center of the ridge, and two leg pieces that hang down from the ridge and face each other.

止め具主体の脚片を所定の板材の孔に挿入し、脚片の一部が孔の裏側から張り出した状態で、挿通孔から挿入したピン部材を押し込んで２つの脚片を拡張することで、２つの脚片を孔の裏側の縁に係止させる。２つの脚片と鍔により所定の板材の孔の縁を挟み、止め具を所定の板材に固着させる。 By inserting the leg piece mainly composed of the stopper into the hole of the predetermined plate material, and extending the two leg pieces by pushing in the pin member inserted from the insertion hole in a state where a part of the leg piece protrudes from the back side of the hole. The two leg pieces are locked to the edge on the back side of the hole. The edge of the hole of a predetermined board | plate material is pinched | interposed with two leg pieces and a collar, and a stopper is fixed to a predetermined board | plate material.

特許文献１に記載の止め具では、孔が形成された板材の厚さが大きくなると、孔の裏側から張り出すことができる脚片の長さが小さくなる。これにより、ピン部材の押し込みにより撓むことできる脚片の長さが小さくなり、脚片を撓ませるのに必要な力が大きくなってピン部材を押し込みづらくなる。 In the stopper described in Patent Document 1, when the thickness of the plate material in which the hole is formed is increased, the length of the leg piece that can be projected from the back side of the hole is decreased. As a result, the length of the leg piece that can be bent by pushing the pin member is reduced, and the force required to bend the leg piece is increased, making it difficult to push the pin member.

本発明はこのような課題に鑑みてなされたものであり、その目的は、留め具を取付部材の取付孔に容易に留めることができる技術を提供することにある。 This invention is made | formed in view of such a subject, The objective is to provide the technique which can fasten a fastener to the attachment hole of an attachment member easily.

上記課題を解決するために、本発明のある態様は、クリップとピン部材とを備え、取付部材の取付孔に挿入されて固定される留め具であって、クリップは、一端に自由端を有し、取付孔に挿入される第１板部と、一端に自由端を有し、取付孔に挿入される第２板部と、第１板部と第２板部とが対向するように第１板部の他端と第２板部の他端とを連結し、ピン部材が挿入される挿入孔を有し、取付部材の表面側に当接するためのフランジ部と、を備える。第１板部および第２板部は、他端側に形成された幅広部と、幅広部より一端側において幅広部より幅方向に狭い幅に形成される幅狭部と、をそれぞれ有する。対向する一対の幅狭部は、一端側において互いに接近するよう屈曲された接近部を有する。ピン部材は、挿入孔から第１板部と第２板部の間に挿入されて押し込まれた場合、一対の接近部を離間させて第１板部と第２板部を拡開させて取付孔の裏側の縁に係合させる。 In order to solve the above-described problem, an aspect of the present invention is a fastener that includes a clip and a pin member and is inserted into and fixed to a mounting hole of the mounting member, and the clip has a free end at one end. The first plate portion inserted into the mounting hole, the second plate portion having a free end at one end and inserted into the mounting hole, and the first plate portion and the second plate portion are opposed to each other. A flange portion for connecting the other end of the first plate portion and the other end of the second plate portion, having an insertion hole into which the pin member is inserted, and contacting the surface side of the mounting member; The first plate portion and the second plate portion each have a wide portion formed on the other end side, and a narrow portion formed in a width narrower in the width direction than the wide portion on one end side from the wide portion. The pair of opposing narrow portions have an approach portion that is bent so as to approach each other on one end side. When the pin member is inserted and inserted between the first plate portion and the second plate portion through the insertion hole, the pair of approach portions are separated from each other and the first plate portion and the second plate portion are expanded to be attached. Engage with the back edge of the hole.

この態様によると、取付部材の厚さが薄い場合は取付孔の縁を幅広部で係止し、取付部材の厚さが厚い場合は取付孔の縁を幅狭部で係止することができる。幅広部で係止する場合、取付孔の縁に接触しやすく、ガタツキを抑えることができる。幅狭部で係止する場合、第１板部および第２板部は撓みやすくなり、ピン部材を挿入する際の力を軽減することができる。 According to this aspect, when the thickness of the mounting member is thin, the edge of the mounting hole can be locked by the wide portion, and when the thickness of the mounting member is thick, the edge of the mounting hole can be locked by the narrow portion. . When locking by the wide part, it is easy to contact the edge of the attachment hole, and rattling can be suppressed. When locking at the narrow portion, the first plate portion and the second plate portion are easily bent, and the force at the time of inserting the pin member can be reduced.

本発明によれば、留め具を取付部材の取付孔に容易に留めることができる。 According to the present invention, the fastener can be easily fastened to the mounting hole of the mounting member.

The fastener 10 includes a clip 20 made of a metal material and a pin member 60 made of a synthetic resin material.

留め具１０は、第１取付孔が形成された第１取付部材に、第２取付孔が形成された第２取付部材を取り付けるために用いられる。たとえば、第１部材は車体パネルであって、第２部材は導電性樹脂チューブや導電性プレートである。留め具１０は、導電性樹脂チューブや導電性プレートを車体パネルにアースする。図１に示す留め具１０は、取付部材に取り付ける前の状態であり、この状態で出荷や輸送がなされる。クリップ２０およびピン部材６０について、部品図を参照しつつ説明する。 The fastener 10 is used for attaching the second attachment member formed with the second attachment hole to the first attachment member formed with the first attachment hole. For example, the first member is a vehicle body panel, and the second member is a conductive resin tube or a conductive plate. The fastener 10 grounds the conductive resin tube and the conductive plate to the vehicle body panel. The fastener 10 shown in FIG. 1 is in a state before being attached to the attachment member, and is shipped and transported in this state. The clip 20 and the pin member 60 will be described with reference to component drawings.

図２は、クリップ２０を説明するための図である。図２（ａ）はクリップ２０を正面からみた図であり、図２（ｂ）はクリップ２０を幅方向からみた図であり、図２（ｃ）は図２（ｂ）のクリップ２０の裏側からみた図である。ここで各図面に示される同一または同等の構成要素、部材には、同一の符号を付するものとし、適宜重複した説明は省略する。 FIG. 2 is a diagram for explaining the clip 20. 2 (a) is a view of the clip 20 as viewed from the front, FIG. 2 (b) is a view of the clip 20 as viewed from the width direction, and FIG. 2 (c) is a view from the back side of the clip 20 in FIG. 2 (b). FIG. Here, the same or equivalent components and members shown in the drawings are denoted by the same reference numerals, and repeated description thereof is omitted as appropriate.

なお、図２（ｃ）に示すＸ方向を、第１板部２２および第２板部２４が対向する対向方向といい、Ｙ方向を第１板部２２および第２板部２４の幅方向という。また、対向方向および幅方向に直交する方向を取付孔への挿入方向またはピン部材６０の軸方向という。 2C is referred to as a facing direction in which the first plate portion 22 and the second plate portion 24 face each other, and the Y direction is referred to as a width direction of the first plate portion 22 and the second plate portion 24. . Further, a direction orthogonal to the facing direction and the width direction is referred to as an insertion direction into the mounting hole or an axial direction of the pin member 60.

クリップ２０は、第１板部２２、第２板部２４、フランジ部２６、リブ３６、屈曲部４８、および屈曲部４２を備える。クリップ２０は、金属板に切り抜き加工およびプレス加工を施して形成される。 The clip 20 includes a first plate portion 22, a second plate portion 24, a flange portion 26, a rib 36, a bent portion 48, and a bent portion 42. The clip 20 is formed by cutting and pressing a metal plate.

図２（ｂ）に示すように、同じ形状である第１板部２２および第２板部２４は対向して配置され、一端はフランジ部２６により連結され、他端は自由端である。フランジ部２６は、第１板部２２と第２板部２４とが対向するように第１板部２２と第２板部２４とを連結し、取付部材の表面側において取付孔の周縁に当接する。フランジ部２６にはピン部材６０を挿入するための挿入孔２８が形成される。 As shown in FIG. 2B, the first plate portion 22 and the second plate portion 24 having the same shape are arranged to face each other, one end is connected by a flange portion 26, and the other end is a free end. The flange portion 26 connects the first plate portion 22 and the second plate portion 24 so that the first plate portion 22 and the second plate portion 24 face each other, and contacts the periphery of the mounting hole on the surface side of the mounting member. Touch. An insertion hole 28 for inserting the pin member 60 is formed in the flange portion 26.

リブ３６は、フランジ部２６に設けられ、フランジ部２６の端部の板面を屈曲して形成される。リブ３６の一端は、第１板部２２または第２板部２４にも連なり、リブ３６によりフランジ部２６の強度が向上する。リブ３６は取付部材の表面側に係止する。 The rib 36 is provided on the flange portion 26 and is formed by bending the plate surface at the end of the flange portion 26. One end of the rib 36 is also connected to the first plate portion 22 or the second plate portion 24, and the strength of the flange portion 26 is improved by the rib 36. The rib 36 is locked to the surface side of the mounting member.

図２（ａ）に示すように第１板部２２は、フランジ部２６側から先端側に向かって順に、第１幅広部２９ａ、第１傾斜部３０ａおよび第１幅狭部３１ａを有する。同じ形状である第２板部２４も同様に、第２幅広部２９ｂ、第２傾斜部３０ｂおよび第２幅狭部３１ｂを有する。第１幅広部２９ａおよび第２幅広部２９ｂを区別しない場合、幅広部２９といい、第１傾斜部３０ａおよび第２傾斜部３０ｂを区別しない場合、傾斜部３０といい、第１幅狭部３１ａおよび第２幅狭部３１ｂを区別しない場合、幅狭部３１という。 As shown in FIG. 2A, the first plate portion 22 includes a first wide portion 29a, a first inclined portion 30a, and a first narrow portion 31a in order from the flange portion 26 side toward the distal end side. Similarly, the second plate portion 24 having the same shape includes a second wide portion 29b, a second inclined portion 30b, and a second narrow portion 31b. When the first wide portion 29a and the second wide portion 29b are not distinguished from each other, the wide portion 29 is referred to. When the first inclined portion 30a and the second inclined portion 30b are not distinguished from each other, the inclined portion 30 is referred to as the first narrow portion 31a. And when it does not distinguish between the 2nd narrow part 31b, it is called the narrow part 31.

傾斜部３０は、幅広部２９と幅狭部３１の間に形成され、幅広部２９から幅狭部３１に向かって幅が狭くなる。また、傾斜部３０は自由端側に向かって幅が狭くなるように側縁が傾斜する。留め具１０を取付部材の取付孔に挿通する際に、傾斜部３０の側縁によって取付孔の縁に付いた塗装を削り、クリップ２０と取付部材を導通することができる。また、傾斜部３０により第１板部２２および第２板部２４の側縁が挿入途中に取付孔の縁に引っかかることを抑えることができる。 The inclined portion 30 is formed between the wide portion 29 and the narrow portion 31, and the width decreases from the wide portion 29 toward the narrow portion 31. In addition, the side edge of the inclined portion 30 is inclined so that the width becomes narrower toward the free end side. When the fastener 10 is inserted into the attachment hole of the attachment member, the coating attached to the edge of the attachment hole by the side edge of the inclined portion 30 can be scraped, and the clip 20 and the attachment member can be conducted. Further, the inclined portion 30 can prevent the side edges of the first plate portion 22 and the second plate portion 24 from being caught by the edge of the attachment hole during insertion.

幅広部２９および幅狭部３１の幅は異なるため、幅広部２９および幅狭部３１のそれぞれでの弾性、すなわち撓みやすさが異なる。幅広部２９および幅狭部３１の幅は一定である。幅広部２９の幅を一定にすることで、取付部材の板厚が薄い場合に取付孔の縁に接触するために必要な幅を確保することができ、アースさせることができる。また、幅狭部３１の幅を一定にすることで、幅狭部３１の撓みやすさを所定値以下に抑えて、幅狭部３１を撓みやすくすることができる。なお幅広部２９の幅は取付孔の直径より小さい。幅広部２９、傾斜部３０および幅狭部３１は、金属板を切り抜くことで容易に加工ができる。取付部材の板厚に応じて幅広部２９、傾斜部３０および幅狭部３１のいずれかが取付部材の裏面側に当接する。 Since the widths of the wide portion 29 and the narrow portion 31 are different, the elasticity of the wide portion 29 and the narrow portion 31, that is, ease of bending, is different. The widths of the wide portion 29 and the narrow portion 31 are constant. By making the width of the wide portion 29 constant, when the plate thickness of the attachment member is thin, the width necessary to contact the edge of the attachment hole can be secured and grounding can be performed. In addition, by making the width of the narrow portion 31 constant, the ease of bending of the narrow portion 31 can be suppressed to a predetermined value or less, and the narrow portion 31 can be easily bent. The width of the wide portion 29 is smaller than the diameter of the mounting hole. The wide portion 29, the inclined portion 30, and the narrow portion 31 can be easily processed by cutting out a metal plate. Depending on the plate thickness of the mounting member, any one of the wide portion 29, the inclined portion 30 and the narrow portion 31 abuts on the back side of the mounting member.

第１板部２２は、第１幅狭部３１ａの自由端側に形成された屈曲部４２を有し、第２板部２４は、第２幅狭部３１ｂの自由端側に形成された屈曲部４８を有する。屈曲部４２は、対向する第２板部２４に接近する接近部３８と、接近部３８から拡開するように折り返された折り返し部４０とを有する。屈曲部４８も対向する接近部３８に接近する接近部４４と、接近部４４の端部から拡開するように折り返された折り返し部４６とを有する。接近部３８，４４は、自由端側において互いに接近するよう屈曲される。折り返し部４０，４６は、自由端に向かって互いに離間するように折り返される。 The first plate portion 22 has a bent portion 42 formed on the free end side of the first narrow portion 31a, and the second plate portion 24 is a bent portion formed on the free end side of the second narrow portion 31b. Part 48. The bent portion 42 includes an approach portion 38 that approaches the opposing second plate portion 24, and a folded portion 40 that is folded back so as to expand from the approach portion 38. The bent portion 48 also has an approaching portion 44 that approaches the facing approaching portion 38 and a folded portion 46 that is folded back so as to expand from the end portion of the approaching portion 44. The approaching portions 38 and 44 are bent so as to approach each other on the free end side. The folded portions 40 and 46 are folded so as to be separated from each other toward the free end.

図２（ａ）および（ｂ）に示すように屈曲部４２に第１切欠部３２ａが形成され、屈曲部４８に第２切欠部３２ｂが形成される。第１切欠部３２ａおよび第２切欠部３２ｂを区別しない場合、切欠部３２という。切欠部３２は、接近部３８，４４と折り返し部４０，４６に渡って形成される。 As shown in FIGS. 2A and 2B, the first cutout portion 32 a is formed in the bent portion 42, and the second cutout portion 32 b is formed in the bent portion 48. When not distinguishing the 1st notch part 32a and the 2nd notch part 32b, it is called the notch part 32. FIG. The notch 32 is formed across the approaching portions 38 and 44 and the folded portions 40 and 46.

図２（ｃ）に示すように第１切欠部３２ａと第２切欠部３２ｂは、接近することでピン部材６０の先端が差し込まれる差込孔４９を画成する。屈曲部４２と屈曲部４８の間にピン部材６０が挿入されることで第１板部２２と第２板部２４が弾性により拡開する。 As shown in FIG. 2C, the first cutout portion 32a and the second cutout portion 32b define an insertion hole 49 into which the tip of the pin member 60 is inserted when approaching. By inserting the pin member 60 between the bent portion 42 and the bent portion 48, the first plate portion 22 and the second plate portion 24 are expanded by elasticity.

図２（ａ）および（ｂ）に示すように、接近部３８の根元部分に内向きに突出する第１内方突部３４ａが形成される。同様に接近部４４に第２内方突部３４ｂが形成される。 As shown in FIGS. 2A and 2B, a first inward protrusion 34 a that protrudes inward is formed at the base portion of the approach portion 38. Similarly, a second inward protrusion 34 b is formed in the approaching portion 44.

図３は、ピン部材６０について説明するための図である。図３（ａ）は、ピン部材６０の一方の側面をみた図であり、ピン部材６０の他方の側面をみた図である。ピン部材６０は、取付孔の直径より大きい頭部６２と、頭部６２から下垂するように設けられた棒状の胴部６４を有する。 FIG. 3 is a view for explaining the pin member 60. FIG. 3A is a view of one side surface of the pin member 60 and a view of the other side surface of the pin member 60. The pin member 60 has a head portion 62 that is larger than the diameter of the mounting hole, and a rod-like body portion 64 that is provided so as to hang down from the head portion 62.

図３（ｂ）に示すように頭部６２は、厚肉部６６と、厚肉部６６より薄い薄肉部６８を有する。取付状態において薄肉部６８にクリップ２０のフランジ部２６が収まり、フランジ部２６の外側に厚肉部６６が位置して取付部材に当接する。 As shown in FIG. 3B, the head 62 has a thick part 66 and a thin part 68 thinner than the thick part 66. In the attached state, the flange portion 26 of the clip 20 is accommodated in the thin-walled portion 68, and the thick-walled portion 66 is positioned outside the flange portion 26 and abuts against the attachment member.

図３（ｂ）に示すように胴部６４は、内部に空隙部７８が形成されており、クリップ２０が変形して胴部６４に接触した場合に撓み可能となっている。胴部６４は、先端突起部７０、側突部７２、係止肩部７４および凸部７６を有する。 As shown in FIG. 3B, the body portion 64 has a gap portion 78 formed therein, and can be bent when the clip 20 is deformed and contacts the body portion 64. The body portion 64 includes a tip protrusion 70, a side protrusion 72, a locking shoulder 74, and a convex portion 76.

先端突起部７０は胴部６４の先端に設けられ、図３（ａ）および（ｂ）に示すように、空隙部７８が形成された胴部６４より、径方向に小さく形成される。先端突起部７０の断面は長孔状に形成される。先端突起部７０が胴部６４より径が小さいため、先端突起部７０の根元には段部８０が形成される。この段部８０にはクリップ２０の屈曲部４２，４８が当接する。 The tip protrusion 70 is provided at the tip of the body 64, and is formed to be smaller in the radial direction than the body 64 in which the gap 78 is formed, as shown in FIGS. The cross section of the tip protrusion 70 is formed in a long hole shape. Since the tip projection 70 is smaller in diameter than the body 64, a step 80 is formed at the root of the tip projection 70. The bent portions 42 and 48 of the clip 20 abut on the stepped portion 80.

側突部７２は、胴部６４の側面に突出するように形成され、留め具１０においてクリップ２０の抜け止めとして機能する。係止肩部７４および凸部７６は、胴部６４の側面に形成され、側突部７２より先端側に位置する。凸部７６はピン部材６０の軸方向に延在する。係止肩部７４は凸部７６と直交する方向に延在する。 The side protrusion 72 is formed so as to protrude from the side surface of the body portion 64, and functions as a stopper for the clip 20 in the fastener 10. The locking shoulder portion 74 and the convex portion 76 are formed on the side surface of the body portion 64 and are located on the distal end side from the side protrusion 72. The convex portion 76 extends in the axial direction of the pin member 60. The locking shoulder 74 extends in a direction orthogonal to the convex portion 76.

図１に戻る。留め具１０は、クリップ２０の挿入孔２８にピン部材６０の胴部６４を挿入して組み付けられる。図１（ｂ）に示すように、第１切欠部３２ａおよび第２切欠部３２ｂにより形成された差込孔４９に先端突起部７０が挿入される。これにより、胴部６４の根元部分および先端部分が挿入孔２８の縁および差込孔４９の縁によって動きが制限されるため、留め具１０のガタツキが抑えられる。この留め具１０の作用について説明する。 Returning to FIG. The fastener 10 is assembled by inserting the body portion 64 of the pin member 60 into the insertion hole 28 of the clip 20. As shown in FIG. 1B, the tip protrusion 70 is inserted into the insertion hole 49 formed by the first notch 32a and the second notch 32b. As a result, the movement of the root portion and the tip portion of the body portion 64 is restricted by the edge of the insertion hole 28 and the edge of the insertion hole 49, so that rattling of the fastener 10 is suppressed. The operation of the fastener 10 will be described.

図４は、取付孔への挿入前の状態の留め具１０について説明するための図である。図４（ａ）は、留め具１０をクリップ２０の幅方向からみた図であり、図４（ｂ）は、留め具１０をクリップ２０の対向方向からみた図であり、図４（ｃ）は、図４（ｂ）のクリップ２０のＡ−Ａの断面であって、第１板部２２および第２板部２４と第１取付孔１２ａの関係を説明する図である。図４（ａ）および（ｂ）では、留め具１０の側面を示すのに対し、第１取付部材１２および第２取付部材１４はその中心を通る断面を示す。図４（ａ）〜（ｃ）はいずれも同じ状態の留め具１０である。 FIG. 4 is a view for explaining the fastener 10 in a state before being inserted into the attachment hole. 4A is a view of the fastener 10 viewed from the width direction of the clip 20, FIG. 4B is a view of the fastener 10 viewed from the opposite direction of the clip 20, and FIG. 4B is a cross-sectional view taken along the line AA of the clip 20 in FIG. 4B, illustrating the relationship between the first plate portion 22 and the second plate portion 24 and the first mounting hole 12 a. 4 (a) and 4 (b), the side surface of the fastener 10 is shown, while the first attachment member 12 and the second attachment member 14 show a cross section passing through the center thereof. 4A to 4C show the fastener 10 in the same state.

第１取付部材１２には第１取付孔１２ａが形成され、第２取付部材１４には第２取付孔１４ａが形成される。第１取付部材１２および第２取付部材１４を特に区別しない場合、取付部材といい、同様に第１取付孔１２ａおよび第２取付孔１４ａを取付孔という。たとえば第１取付部材１２は車体パネルであり、第２取付部材１４は導電性プレートである。図４（ａ）に示すように、頭部６２の外径は第２取付孔１４ａより大きく、ピン部材６０押し込むと頭部６２が第２取付部材１４の表面に当接する。また頭部６２の薄肉部６８は、フランジ部２６より少し大きく形成されており、ピン部材６０を押し込むとフランジ部２６は薄肉部６８により形成された空間に収まる。 A first mounting hole 12 a is formed in the first mounting member 12, and a second mounting hole 14 a is formed in the second mounting member 14. When the first attachment member 12 and the second attachment member 14 are not particularly distinguished, they are referred to as attachment members, and similarly, the first attachment hole 12a and the second attachment hole 14a are referred to as attachment holes. For example, the first mounting member 12 is a vehicle body panel, and the second mounting member 14 is a conductive plate. As shown in FIG. 4A, the outer diameter of the head 62 is larger than that of the second mounting hole 14 a, and when the pin member 60 is pushed in, the head 62 comes into contact with the surface of the second mounting member 14. The thin portion 68 of the head 62 is formed to be slightly larger than the flange portion 26, and when the pin member 60 is pushed in, the flange portion 26 fits in the space formed by the thin portion 68.

留め具１０は、クリップ２０およびピン部材６０を一体化した状態で輸送されるため、輸送中にクリップ２０とピン部材６０が外れないようにすることが好ましい。図４（ａ）に示すように、ピン部材６０の胴部６４を挿入孔２８に挿入した状態において、側突部７２によってフランジ部２６（クリップ２０）が頭部６２から離間する方向に相対移動することが制限されている。また、屈曲部４２，４８は、係止肩部７４および段部８０に係止し、フランジ部２６と頭部６２が接近する方向に相対移動することを制限する。このように、フランジ部２６と屈曲部４２，４８により胴部６４を挟むようにクリップ２０がピン部材６０に固定されているため、クリップ２０とピン部材６０が外れる可能性が低減される。また、一対の切欠部３２により形成された挿入孔に先端突起部７０が挿入されて、胴部６４の軸ぶれも抑えられており、輸送中にクリップ２０およびピン部材６０が外れる可能性がより低減されている。 Since the fastener 10 is transported in a state where the clip 20 and the pin member 60 are integrated, it is preferable that the clip 20 and the pin member 60 are not detached during transportation. As shown in FIG. 4A, the flange portion 26 (clip 20) is relatively moved away from the head portion 62 by the side protrusion 72 in a state where the body portion 64 of the pin member 60 is inserted into the insertion hole 28. To be restricted. Further, the bent portions 42 and 48 are locked to the locking shoulder portion 74 and the stepped portion 80 and restrict relative movement in the direction in which the flange portion 26 and the head portion 62 approach each other. In this way, since the clip 20 is fixed to the pin member 60 so that the body portion 64 is sandwiched between the flange portion 26 and the bent portions 42 and 48, the possibility that the clip 20 and the pin member 60 come off is reduced. Further, the tip protrusion 70 is inserted into the insertion hole formed by the pair of notches 32, and the shaft 64 is prevented from being shaken, and the clip 20 and the pin member 60 may be detached during transportation. Has been reduced.

第１板部２２および第２板部２４は、所定間隔離れて対向し、対向方向に撓み可能である。第２取付部材１４の板厚が比較的厚いため、第１取付孔１２ａの裏面側の縁には幅狭部３１が位置する。なお幅狭部３１が第１取付孔１２ａと接触する場合、第１板部２２と第１取付孔１２ａとの間隔Ｌ１は、幅広部２９が第１取付孔１２ａと接触する場合と比べて狭くなる。間隔Ｌ１は、幅狭部３１の両側縁が第１取付孔１２ａに接触した状態での、幅狭部３１の幅方向中央と第１取付孔１２ａとの間隔である。 The first plate portion 22 and the second plate portion 24 face each other at a predetermined interval and can be bent in the facing direction. Since the plate thickness of the second mounting member 14 is relatively thick, the narrow portion 31 is located at the edge on the back surface side of the first mounting hole 12a. When the narrow portion 31 is in contact with the first mounting hole 12a, the distance L1 between the first plate portion 22 and the first mounting hole 12a is narrower than when the wide portion 29 is in contact with the first mounting hole 12a. Become. The space | interval L1 is a space | interval of the width direction center of the narrow part 31 and the 1st mounting hole 12a in the state which the both-sides edge of the narrow part 31 contacted the 1st mounting hole 12a.

作業者が留め具１０を取り付けるためピン部材６０の頭部６２を押し込んだ場合、ピン部材６０の胴部６４によりクリップ２０の屈曲部４２，４８が押されるが、フランジ部２６が第２取付部材１４の表面側に当接しているためクリップ２０は移動せず、ピン部材６０のみが押し込まれる。このときピン部材６０の係止肩部７４および段部８０は、屈曲部４２，４８の接近部３８，４４に接触して第１板部２２と第２板部２４を拡開させながら押し込まれる。このとき、幅狭部３１の側縁により第１取付部材１２の接触部分の塗装を剥がし、クリップ２０を介して第２取付部材１４を第１取付部材１２にアースすることができる。頭部６２が第２取付部材１４の表面側に当接すると取付が完了する。 When the operator pushes the head portion 62 of the pin member 60 in order to attach the fastener 10, the bent portions 42 and 48 of the clip 20 are pushed by the body portion 64 of the pin member 60, but the flange portion 26 is the second attachment member. 14, the clip 20 does not move and only the pin member 60 is pushed in. At this time, the locking shoulder portion 74 and the stepped portion 80 of the pin member 60 are pressed in contact with the approaching portions 38 and 44 of the bent portions 42 and 48 while expanding the first plate portion 22 and the second plate portion 24. . At this time, the contact portion of the first mounting member 12 is peeled off by the side edge of the narrow portion 31, and the second mounting member 14 can be grounded to the first mounting member 12 via the clip 20. The attachment is completed when the head 62 abuts on the surface side of the second attachment member 14.

ここで、作業者がピン部材６０押し込んでフランジ部２６が第２取付部材１４の表面側に当接したときに、フランジ部２６の剛性が低すぎると、フランジ部２６が過剰に変形して取り付けができないおそれがある。そこで、フランジ部２６の端部を折り曲げてリブ３６を形成することで、フランジ部２６の剛性を高め、取り付け時にフランジ部２６が過剰に変形することを抑えることができる。 Here, if the rigidity of the flange portion 26 is too low when the operator pushes the pin member 60 and the flange portion 26 comes into contact with the surface side of the second attachment member 14, the flange portion 26 is excessively deformed and attached. You may not be able to. Therefore, by bending the end portion of the flange portion 26 to form the rib 36, it is possible to increase the rigidity of the flange portion 26 and to prevent the flange portion 26 from being excessively deformed during attachment.

図５は、取付孔に取り付けた状態の留め具１０について説明するための図である。図５（ａ）は、留め具１０をクリップ２０の幅方向からみた図であり、図５（ｂ）は、留め具１０をクリップ２０の対向方向からみた図であり、図５（ｃ）は、図５（ｂ）の留め具１０の線分Ｂ−Ｂの断面図であり、第１板部２２および第２板部２４と第１取付孔１２ａの関係を説明する図である。図５（ａ）〜（ｃ）は、図４に示す挿入途中の状態から、さらにピン部材６０を取付孔に押し込み、取付が完了した状態を示す。 FIG. 5 is a view for explaining the fastener 10 in a state of being attached to the attachment hole. 5A is a view of the fastener 10 viewed from the width direction of the clip 20, FIG. 5B is a view of the fastener 10 viewed from the opposite direction of the clip 20, and FIG. FIG. 5B is a cross-sectional view taken along line B-B of the fastener 10 in FIG. 5B, and is a diagram illustrating the relationship between the first plate portion 22 and the second plate portion 24 and the first mounting hole 12 a. 5A to 5C show a state in which the pin member 60 is further pushed into the mounting hole from the state in the middle of insertion shown in FIG. 4 and the mounting is completed.

図５（ａ）に示すように、第１板部２２および第２板部２４において第１取付孔１２ａの裏側に出た部分、すなわち第１取付孔１２ａと接触した位置から先端側の部分が拡開するように撓んでいる。これにより、フランジ部２６と幅狭部３１により取付孔の表側および裏側の縁を挟むように係止し、留め具１０のガタツキなく留めることができる。第１板部２２および第２板部２４において第１取付孔１２ａと接触した位置から先端側の部分の長さを「張り出し長さ」という。 As shown in FIG. 5 (a), in the first plate portion 22 and the second plate portion 24, the portion protruding to the back side of the first mounting hole 12a, that is, the portion on the tip side from the position in contact with the first mounting hole 12a It bends to expand. Thereby, it can latch so that the edge of the front side and back side of a mounting hole may be pinched | interposed by the flange part 26 and the narrow part 31, and it can fasten without the rattle 10 rattling. In the first plate portion 22 and the second plate portion 24, the length of the portion on the distal end side from the position in contact with the first mounting hole 12 a is referred to as “overhang length”.

車両に留め具１０を取り付けると車両から振動を受ける。このとき留め具１０ががたつくとアースができない可能性がある。図５（ａ）に示すように、係止肩部７４に屈曲部４８が拡開した状態で係止しており、屈曲部４８に形成された切欠部３２に凸部７６が収まっている。これにより拡開した第１板部２２および第２板部２４を係止でき、取付後のガタツキを抑えることができる。 When the fastener 10 is attached to the vehicle, it receives vibration from the vehicle. If the fastener 10 rattles at this time, there is a possibility that grounding cannot be performed. As shown in FIG. 5A, the bent shoulder 48 is locked in a state where the bent portion 48 is expanded, and the convex portion 76 is accommodated in the cutout portion 32 formed in the bent portion 48. Thereby, the 1st board part 22 and the 2nd board part 24 which were expanded can be latched, and the rattling after attachment can be suppressed.

ここで、取付部材の板厚が厚くなり、第１板部２２および第２板部２４の張り出し長さが短くなれば、第１板部２２および第２板部２４は撓みづらくなる。しかしながら、幅狭部３１は、幅広部２９と比べて撓みやすいため、取付部材の板厚が厚くなってもピン部材６０の押し込みに必要な力を抑えることができ、作業者は容易に取付作業ができる。 Here, if the plate | board thickness of an attachment member becomes thick and the overhang length of the 1st board part 22 and the 2nd board part 24 becomes short, the 1st board part 22 and the 2nd board part 24 will become difficult to bend. However, since the narrow portion 31 is more easily bent than the wide portion 29, the force required to push the pin member 60 can be suppressed even when the plate thickness of the mounting member is increased, and the operator can easily perform the mounting operation. Can do.

図６は、図５より板厚が薄い取付部材の取付孔に取り付けた状態の留め具１０について説明するための図である。図６（ａ）は、留め具１０をクリップ２０の幅方向からみた図であり、図６（ｂ）は、留め具１０をクリップ２０の対向方向からみた図であり、図６（ｃ）は、図６（ｂ）の留め具１０の線分Ｃ−Ｃの断面図であり、第１板部２２および第２板部２４と第１取付孔１２ａの関係を説明する図である。図６（ａ）〜（ｃ）は、取付が完了した状態を示す。 FIG. 6 is a view for explaining the fastener 10 in a state of being attached to the attachment hole of the attachment member whose thickness is thinner than that of FIG. 5. 6A is a view of the fastener 10 as viewed from the width direction of the clip 20, FIG. 6B is a view of the fastener 10 as viewed from the opposite direction of the clip 20, and FIG. 6B is a cross-sectional view taken along line C-C of the fastener 10 in FIG. 6B, and is a view for explaining the relationship between the first plate portion 22 and the second plate portion 24 and the first mounting hole 12 a. 6A to 6C show a state where the attachment is completed.

図６（ａ）に示す第２取付部材１６は、図５（ａ）に示す第２取付部材１４より板厚が薄い。そのため、第１板部２２および第２板部２４の取付孔からの張り出し長さは長くなり、第１板部２２および第２板部２４は撓みやすくなる。そのため、ピン部材６０の押し込みは容易にできるが、幅広部２９により第１取付孔１２ａの縁に係止する力が弱まりうる。しかしながら、図６（ｃ）に示すように、第１板部２２の幅広部２９と第１取付孔１２ａとの間隔Ｌ２は、幅狭部３１が第１取付孔１２ａと接触する場合と比べて大きく、幅広部２９は幅狭部３１より幅方向に広く、ほとんど撓まなくとも第１取付孔１２ａに接触可能である。したがって幅広部２９の係止力を高めることができる。このように、取付部材の板厚が変化しても、留め具１０を強固に係止させることができる。また、幅広部２９により第１取付孔１２ａの縁に接触しやすくすることで、精度高くアースさせることができる。 The second mounting member 16 shown in FIG. 6A is thinner than the second mounting member 14 shown in FIG. For this reason, the length of the first plate portion 22 and the second plate portion 24 protruding from the mounting holes is increased, and the first plate portion 22 and the second plate portion 24 are easily bent. Therefore, although the pin member 60 can be pushed in easily, the force of locking to the edge of the first mounting hole 12a by the wide portion 29 can be weakened. However, as shown in FIG. 6C, the interval L2 between the wide portion 29 of the first plate portion 22 and the first mounting hole 12a is compared to the case where the narrow portion 31 contacts the first mounting hole 12a. The large and wide portion 29 is wider than the narrow portion 31 in the width direction, and can contact the first mounting hole 12a with little bending. Therefore, the locking force of the wide portion 29 can be increased. Thus, even if the plate | board thickness of an attachment member changes, the fastener 10 can be latched firmly. Further, by making the wide portion 29 easily contact the edge of the first mounting hole 12a, it is possible to ground with high accuracy.

However, the present invention is not limited to this. For example, the first plate portion 22 and the second plate portion 24 may be configured such that the width gradually decreases from the flange portion 26 toward the narrow portion 31. That is, the wide portion is formed on the flange portion side from the narrow portion 31, is wider than the narrow portion 31, and the side edge is inclined toward the narrow portion 31. The clip 20 can be firmly locked to the edge of the mounting hole depending on the thickness of the mounting member according to this aspect.
