Description

本発明は、樹脂材で形成されたフック部材と、金属材により形成された取付部材とを備えるフック装置に関する。 The present invention relates to a hook device including a hook member formed of a resin material and an attachment member formed of a metal material.

車両の室内のドアフレームとドアフレームガーニッシュとの間にフック装置が取り付けられ、サンシェードの骨組みを掛けるために使用される（特許文献１参照）。ここで従来技術について図１１を参照して説明する。 A hook device is attached between a door frame and a door frame garnish in a vehicle interior, and is used to hang a framework of a sunshade (see Patent Document 1). Here, the prior art will be described with reference to FIG.

図１１は、従来技術のフック装置１００の断面図を示す。フック装置１００は先端が屈曲して形成された金属板部材１２０と、金属板部材１２０の一部を覆う樹脂部材１４０から構成される。金属板部材１２０はドアフレームに取り付けられる取付部１２２と、フック状に屈曲して形成された屈曲部１２４を有する。フック装置１００は、金属板部材１２０をプレス加工して取付部１２２と屈曲部１２４を形成した後、インサート成形により樹脂部材１４０で金属板部材１２０の一部を覆う。これにより、金属材が車両室内に露出することを避けることができる。 FIG. 11 shows a cross-sectional view of a hook device 100 of the prior art.

従来技術のフック装置１００は、金属板部材１２０を加工してからインサート成形により金属板部材１２０の外周に樹脂部材１４０を形成しており、コストがかかる。また、フック状の屈曲部１２４まで金属板が入っているためフック装置１００が重くなる。 The hook device 100 of the prior art forms the resin member 140 on the outer periphery of the metal plate member 120 by insert molding after processing the metal plate member 120, which is costly. Further, since the metal plate is contained up to the hook-shaped bent portion 124, the hook device 100 becomes heavy.

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、製造コストを抑えて軽量化をしたフック装置を提供することにある。 The present invention has been made in view of such problems, and an object of the present invention is to provide a hook device that is reduced in weight while suppressing manufacturing costs.

上記課題を解決するために、本発明のある態様のフック装置は、樹脂材で形成されたフック部材と、金属材により形成された取付部材とを備えるフック装置であって、フック部材は、一端側を屈曲して形成された屈曲部と、他端に開口して形成された挿入孔を有する基部と、を有する。取付部材は、車体に取り付けるための取付部と、フック部材の挿入孔に挿入する挿入部と、を有する。取付部材の挿入部は、隣合う一対の脚部と、一対の脚部を連結する抜け止め部と、を有する。フック部材の基部は、挿入された抜け止め部の抜け方向の移動を規制する規制部を有する。 In order to solve the above problems, a hook device according to an aspect of the present invention is a hook device including a hook member formed of a resin material and an attachment member formed of a metal material, and the hook member has one end. It has a bent portion formed by bending the side, and a base portion having an insertion hole formed to open at the other end. The attachment member has an attachment portion for attachment to the vehicle body and an insertion portion to be inserted into the insertion hole of the hook member. The insertion portion of the attachment member includes a pair of adjacent leg portions and a retaining portion that connects the pair of leg portions. The base portion of the hook member has a restricting portion that restricts movement of the inserted retaining portion in the removal direction.

この態様によると、取付部材とフック部材を別々に成形して、フック部材の挿入孔に取付部材を挿入して組み付けできるため、製造コストを抑えることができる。また、フック部材の屈曲部を樹脂材により形成することでフック装置の軽量化ができる。 According to this aspect, the mounting member and the hook member can be separately molded, and the mounting member can be inserted and assembled into the insertion hole of the hook member, so that the manufacturing cost can be reduced. Further, the hook device can be reduced in weight by forming the bent portion of the hook member with a resin material.

本発明によれば、フック装置において、製造コストを抑えて軽量化できる。 According to the present invention, the hook device can be reduced in weight while suppressing the manufacturing cost.

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.

フック装置１０は、樹脂材で形成されたフック部材４０と、金属材により形成された取付部材２０とを備える。フック装置１０は、車両の窓枠上側のドアフレームに取り付けられ、サンシェードによって窓を塞いだ場合にサンシェードの骨組みを掛けるために用いられる。フック装置１０は、ドアフレームの狭い箇所に取り付けられるため、金属材の取付部材２０により強固に固定される。また車両室内に金属材が露出することを避けるため、室内に露出する部分は合成樹脂材により形成される。このフック装置１０の各部材について部品図を参照しつつ説明する。 The hook device 10 includes a hook member 40 formed of a resin material and an attachment member 20 formed of a metal material. The hook device 10 is attached to a door frame on the upper side of a window frame of a vehicle, and is used to hang a framework of the sunshade when the window is closed with the sunshade. Since the hook device 10 is attached to a narrow portion of the door frame, the hook device 10 is firmly fixed by the metal attachment member 20. Further, in order to avoid exposing the metal material in the vehicle compartment, the portion exposed in the compartment is formed of a synthetic resin material. Each member of the hook device 10 will be described with reference to component drawings.

図２は、取付部材２０の斜視図である。図２（ａ）は表側からみた取付部材２０の図であり、図２（ｂ）は裏側からみた取付部材２０の図である。取付部材２０は、板状の金属材を切り抜き、プレスして形成される。 FIG. 2 is a perspective view of the mounting member 20. FIG. 2A is a view of the mounting member 20 viewed from the front side, and FIG. 2B is a view of the mounting member 20 viewed from the back side. The attachment member 20 is formed by cutting out and pressing a plate-shaped metal material.

取付部材２０は、車両のドアフレームに取り付けるための取付部２２と、フック部材４０の挿入孔に挿入する挿入部２４と、取付部２２と挿入部２４とを連結する連結部２３とを有する。取付部２２は、２枚の金属材が対向するように折り曲げて形成される。取付部２２の中央に形成された切欠により軽量化されている。取付部２２の折り曲げ部２２ａからドアフレームの隙間に挿入して取り付けられる。 The attachment member 20 includes an attachment portion 22 for attachment to a vehicle door frame, an insertion portion 24 to be inserted into an insertion hole of the hook member 40, and a connecting portion 23 for connecting the attachment portion 22 and the insertion portion 24. The attachment portion 22 is formed by bending so that two metal materials face each other. The weight is reduced by a notch formed in the center of the attachment portion 22. It is inserted and attached to the gap of the door frame from the bent portion 22a of the attachment portion 22.

挿入部２４は、取付部２２を屈曲して形成され、取付部２２に対して傾斜する。挿入部２４は平板状であり、隣合う一対の脚部２６と、一対の脚部２６を連結する抜け止め部２８と、を有する。一対の脚部２６は、平行に延在し、その中途で抜け止め部２８により連結される。すなわち一対の脚部２６は、抜け止め部２８により連結された位置からさらに伸びるよう形成される。一対の脚部２６と抜け止め部２８により、第１空隙部３０と第２空隙部３２が形成される。これにより軽量化できる。 The insertion portion 24 is formed by bending the attachment portion 22 and is inclined with respect to the attachment portion 22. The insertion portion 24 has a flat plate shape and includes a pair of adjacent leg portions 26 and a retaining portion 28 that connects the pair of leg portions 26. The pair of leg portions 26 extend in parallel, and are connected by a retaining portion 28 in the middle thereof. That is, the pair of leg portions 26 are formed so as to extend further from the position connected by the retaining portion 28. The pair of leg portions 26 and the retaining portion 28 form a first gap portion 30 and a second gap portion 32. This can reduce the weight.

It is. 5A is a rear view of the hook member 40, and FIG. 5B is a cross-sectional view taken along line BB of the hook member 40 shown in FIG. 5A. (c) is sectional drawing of line segment CC of the hook member 40 shown to Fig.5 (a).

フック部材４０は、一端側を屈曲して形成された屈曲部４４と、他端に開口して形成された挿入孔４６を有する基部４２と、を有する。屈曲部４４には、サンシェードの骨組みが引っ掛けられる。 The hook member 40 has a bent portion 44 formed by bending one end side, and a base portion 42 having an insertion hole 46 formed open at the other end. A sunshade framework is hooked on the bent portion 44.

挿入孔４６には取付部材２０の挿入部２４が挿入される。挿入孔４６の内周も挿入部２４の形状に応じて平板状である。基部４２は、挿入孔４６を挟んで表側壁部５２と裏側壁部５４を有する。図３（ｂ）に示すように、破線にて挿入孔４６の形状が示されている。図３（ｂ）および図５（ａ）に示すように裏側壁部５４には開口部５０が形成され、挿入孔４６と連通する。 The insertion portion 24 of the attachment member 20 is inserted into the insertion hole 46. The inner periphery of the insertion hole 46 is also flat according to the shape of the insertion portion 24. The base portion 42 has a front side wall portion 52 and a back side wall portion 54 with the insertion hole 46 interposed therebetween. As shown in FIG. 3B, the shape of the insertion hole 46 is indicated by a broken line. As shown in FIGS. 3B and 5A, an opening 50 is formed in the back side wall 54 and communicates with the insertion hole 46.

図３（ｂ）および図４（ｂ）に示すように表側壁部５２の内面に規制部４８と、規制部４８より屈曲部４４側に隆起部５８が形成される。規制部４８は、表側壁部５２の内面から突出するように形成される。規制部４８は加工が容易である。開口部５０は、規制部４８および隆起部５８を形成するための金型の抜き孔である。挿入部２４が挿入されると、第１空隙部３０に規制部４８が収まり、第２空隙部３２に隆起部５８が収まる。 As shown in FIGS. 3B and 4B, a restricting portion 48 is formed on the inner surface of the front side wall portion 52, and a raised portion 58 is formed on the bent portion 44 side from the restricting portion 48. The restricting portion 48 is formed so as to protrude from the inner surface of the front side wall portion 52. The restricting portion 48 is easy to process. The opening 50 is a die hole for forming the restricting portion 48 and the raised portion 58. When the insertion portion 24 is inserted, the restriction portion 48 is accommodated in the first gap portion 30 and the raised portion 58 is accommodated in the second gap portion 32.

図４（ｂ）に示すように挿入孔４６の両方の側部４６ａは、奥側から開口に向かって拡開するように傾斜している。これにより、成形する際において挿入孔４６を形成するための金型を容易に抜くことができる。 As shown in FIG. 4B, both side portions 46a of the insertion hole 46 are inclined so as to expand from the back side toward the opening. Thereby, the metal mold | die for forming the insertion hole 46 can be easily extracted at the time of shaping | molding.

図５（ｂ）および（ｃ）に示すように、挿入孔４６には、最奥に一対の脚部２６の先端部分を収容するための先端挿入孔５６がそれぞれ形成される。基部４２に先端挿入孔５６を設けることで、基部４２の端まで金属材を挿入でき、剛性を高めることができる。 As shown in FIGS. 5B and 5C, the insertion hole 46 is formed with a distal end insertion hole 56 for accommodating the distal end portions of the pair of leg portions 26 at the innermost position. By providing the distal end insertion hole 56 in the base portion 42, a metal material can be inserted up to the end of the base portion 42, and the rigidity can be increased.

図６は、フック装置１０を説明するための図である。図６（ａ）は、フック装置１０の側面図であり、図６（ｂ）は、フック装置１０の裏面図であり、図６（ｃ）は、図６（ｂ）に示すフック装置１０の線分Ｄ−Ｄの断面図である。 FIG. 6 is a diagram for explaining the hook device 10. 6 (a) is a side view of the hook device 10, FIG. 6 (b) is a back view of the hook device 10, and FIG. 6 (c) is a diagram of the hook device 10 shown in FIG. 6 (b). It is sectional drawing of line segment DD.

図６（ａ）に示すようにサンシェードの骨組み１２は、屈曲部４４に引っ掛けられる。図６（ｂ）に示すように、第１空隙部３０に規制部４８が収まり、第２空隙部３２に隆起部５８が収まる。隆起部５８を設けることで、取付部材２０の幅方向の動きを規制することができ、ガタツキを抑えることができる。 As shown in FIG. 6A, the sunshade framework 12 is hooked on the bent portion 44. As shown in FIG. 6B, the restricting portion 48 is accommodated in the first gap portion 30, and the raised portion 58 is accommodated in the second gap portion 32. By providing the raised portion 58, the movement of the mounting member 20 in the width direction can be restricted, and rattling can be suppressed.

図６（ｃ）に示すように、規制部４８に抜け止め部２８が係止されている。これにより、規制部４８は、挿入された抜け止め部２８の抜け方向の移動を規制する。抜け方向とは、フック部材４０から取付部材２０が外れる方向であって、挿入孔４６の奥から開口に向かう方向である。屈曲部４４には、金属材が内蔵されておらず、フック装置１０が軽量化されている。 As shown in FIG. 6C, the retaining portion 28 is locked to the restricting portion 48. Thereby, the regulation part 48 regulates the movement of the inserted retaining part 28 in the withdrawal direction. The removal direction is a direction in which the attachment member 20 is detached from the hook member 40 and is a direction from the back of the insertion hole 46 toward the opening. The bent portion 44 does not contain a metal material, and the hook device 10 is reduced in weight.

図６（ａ）に示すようにフック部材４０は取付部２２に対して傾斜しており、フック部材４０の裏面に形成された開口部５０が屈曲部４４側の近傍に形成されると、開口部５０が乗車者から見やすい位置に配置され、デザイン性が低下する。開口部５０は、規制部４８を設けるために形成されるため、規制部４８の位置を挿入孔４６の開口側に配置すればよい。 As shown in FIG. 6 (a), the hook member 40 is inclined with respect to the attachment portion 22. When the opening 50 formed on the back surface of the hook member 40 is formed in the vicinity of the bent portion 44, the opening is formed. The part 50 is arranged at a position that is easy to see from the rider, and the design is reduced. Since the opening 50 is formed to provide the restricting portion 48, the position of the restricting portion 48 may be arranged on the opening side of the insertion hole 46.

そこで、挿入部２４の中途に抜け止め部２８を設け、規制部４８の位置を基部４２の中途に形成するようにしている。規制部４８は、基部４２の中間の位置に形成される。これにより、開口部５０の位置を基部４２の下端から離して、目立たなくさせ、デザイン性を高めることができる。また一対の脚部２６が、抜け止め部２８からさらに伸びるよう形成され、先端挿入孔５６に挿入されることで、抜け止め部２８の位置を基部４２の中間に形成しつつも、基部４２の剛性を高めることができる。 Therefore, the retaining portion 28 is provided in the middle of the insertion portion 24 so that the position of the restricting portion 48 is formed in the middle of the base portion 42. The restricting portion 48 is formed at an intermediate position of the base portion 42. Thereby, the position of the opening part 50 can be separated from the lower end of the base part 42 to make it inconspicuous, and the design can be improved. The pair of leg portions 26 are formed so as to extend further from the retaining portion 28 and are inserted into the distal end insertion hole 56 so that the position of the retaining portion 28 is formed in the middle of the base portion 42, while Stiffness can be increased.

以上のように、フック装置１０は、フック部材４０の挿入孔４６に取付部材２０の挿入部２４を挿入することで組み付けられる。取付部材２０とフック部材４０を別々に成形し、単に挿入するだけで容易に組み付けできるため、製造コストを抑えることができる。 As described above, the hook device 10 is assembled by inserting the insertion portion 24 of the attachment member 20 into the insertion hole 46 of the hook member 40. Since the mounting member 20 and the hook member 40 are formed separately and can be easily assembled by simply inserting, the manufacturing cost can be reduced.

図７は、第１変形例のフック装置６０を説明するための図である。図７（ａ）は、フック装置６０の斜視図であり、図７（ｂ）は、フック装置６０の裏面図であり、図７（ｃ）は、図７（ｂ）に示すフック装置６０の線分Ｅ−Ｅの断面図である。 FIG. 7 is a view for explaining a hook device 60 of a first modification. 7A is a perspective view of the hook device 60, FIG. 7B is a rear view of the hook device 60, and FIG. 7C is a diagram of the hook device 60 shown in FIG. 7B. It is sectional drawing of line segment EE.

第１変形例のフック装置６０は、フック装置１０と比べて抜け止め構造が異なる。フック装置６０では、弾性爪体６４により取付部材２０の抜け止め部２８の抜け方向の移動を規制する。弾性爪体６４は、取付部材２０をフック装置６０の挿入孔４６に挿入する際に、拡開するため容易に組み付けることができる。 The hook device 60 of the first modified example is different from the hook device 10 in the retaining structure. In the hook device 60, movement of the retaining portion 28 of the attachment member 20 in the removal direction is restricted by the elastic claw body 64. The elastic claw body 64 can be easily assembled to expand when the attachment member 20 is inserted into the insertion hole 46 of the hook device 60.

図７（ａ）に示すように、弾性爪体６４は、開口部５０の内部で、取付部材２０の挿入部２４の挿入方向に沿って延在する。取付部材２０の挿入方向とは、挿入孔４６の開口から奥に向かう方向である。 As shown in FIG. 7A, the elastic claw body 64 extends along the insertion direction of the insertion portion 24 of the mounting member 20 inside the opening 50. The insertion direction of the attachment member 20 is a direction from the opening of the insertion hole 46 toward the back.

図７（ｃ）に示すように弾性爪体６４には、取付部材２０の抜け止め部２８が係止されている。弾性爪体６４は、挿入孔４６の開口部５０側で基部４２の裏側壁部５４に連結し、屈曲部４４側の先端に形成された爪部６４ａを有する。爪部６４ａは、挿入孔４６の内向き、つまり表側壁部５２に向かって突き出す。爪部６４ａにより抜け止め部２８の抜き方向の移動を規制する。 As shown in FIG. 7C, the retaining member 28 of the mounting member 20 is locked to the elastic claw body 64. The elastic claw body 64 is connected to the back side wall portion 54 of the base portion 42 on the opening 50 side of the insertion hole 46 and has a claw portion 64a formed at the tip on the bent portion 44 side. The claw portion 64 a protrudes inward of the insertion hole 46, that is, toward the front side wall portion 52. The movement of the retaining portion 28 in the removal direction is restricted by the claw portion 64a.

図７（ａ）および（ｃ）に示すように、挿入孔４６の開口の裏側壁部５４には切欠部４７が形成される。切欠部４７は、挿入孔４６の開口を切り欠いて形成され、他の開口の部分より凹んでいる。制限部６２の根元部分が微少な隙間を介して切欠部４７に入り、制限部６２の幅方向の移動が切欠部４７により規制される。切欠部４７と制限部６２の幅方向の長さは略同一であってよい。図４（ｂ）に示すように挿入孔４６の側部４６ａに金型を抜くための傾斜を形成すると、取付部材２０を挿入孔４６に挿入した場合にガタツキが生じうる。そこで、切欠部４７に制限部６２を入れることで取付部材２０の幅方向のガタツキを抑えることができる。次に取付部材２０について説明する。 As shown in FIGS. 7A and 7C, a notch 47 is formed in the back side wall 54 of the opening of the insertion hole 46. The cutout portion 47 is formed by cutting out the opening of the insertion hole 46 and is recessed from other openings. The base portion of the restricting portion 62 enters the notch 47 through a minute gap, and the movement of the restricting portion 62 in the width direction is restricted by the notch 47. The lengths in the width direction of the notches 47 and the restricting portions 62 may be substantially the same. As shown in FIG. 4B, when the side portion 46 a of the insertion hole 46 is inclined to pull out the mold, rattling may occur when the mounting member 20 is inserted into the insertion hole 46. Therefore, by providing the restricting portion 62 in the notch 47, the mounting member 20 can be prevented from rattling in the width direction. Next, the attachment member 20 will be described.

図８は、第１変形例の取付部材２０の斜視図である。取付部材２０は、取付部２２と、挿入部２４と、取付部２２および挿入部２４を連結する連結部２３を有する。挿入部２４は、一対の脚部２６と、一対の脚部２６を連結する抜け止め部２８を有する。 FIG. 8 is a perspective view of the attachment member 20 of the first modification. The attachment member 20 includes an attachment portion 22, an insertion portion 24, and a connecting portion 23 that connects the attachment portion 22 and the insertion portion 24. The insertion portion 24 includes a pair of leg portions 26 and a retaining portion 28 that connects the pair of leg portions 26.

第１変形例の取付部材２０は、第１空隙部３０を切り欠いて形成した制限部６２を有する。すなわち制限部６２は、成形前に一対の脚部２６の間に位置していた部分を、屈曲して形成される。そのため制限部６２の加工が容易である。制限部６２は、フック部材４０の弾性爪体６４の拡開を制限する。制限部６２は、連結部２３から取付部材２０の先端側に向かって延在する。 The attachment member 20 of the first modification has a limiting portion 62 formed by cutting out the first gap portion 30. That is, the restricting portion 62 is formed by bending a portion located between the pair of leg portions 26 before molding. Therefore, the processing of the restricting portion 62 is easy. The restricting portion 62 restricts the expansion of the elastic claw body 64 of the hook member 40. The restricting portion 62 extends from the connecting portion 23 toward the distal end side of the mounting member 20.

図７に戻る。フック部材４０の挿入孔４６に挿入部２４を挿入して組み付ける際に、抜け止め部２８は爪部６４ａに接触して弾性爪体６４を拡開する。そのため容易に組み付けられるものの、弾性爪体６４の拡開によりフック部材４０から取付部材２０が外れる可能性もある。そこで、図７（ｃ）に示すように制限部６２は、弾性爪体６４が拡開した場合に、弾性爪体６４の中間部分に当接して弾性爪体６４の拡開を制限する。これにより、フック部材４０から取付部材２０が外れる可能性を低減できる。 Returning to FIG. When the insertion portion 24 is inserted into the insertion hole 46 of the hook member 40 and assembled, the retaining portion 28 contacts the claw portion 64a to expand the elastic claw body 64. Therefore, although it is easily assembled, the attachment member 20 may be detached from the hook member 40 due to the expansion of the elastic claw body 64. Therefore, as shown in FIG. 7C, when the elastic claw body 64 is expanded, the restricting portion 62 abuts against an intermediate portion of the elastic claw body 64 to limit the expansion of the elastic claw body 64. Thereby, possibility that the attachment member 20 will remove | deviate from the hook member 40 can be reduced.

弾性爪体６４の中間部分は、たとえば弾性爪体６４の外面の中央である。制限部６２が、制限部６２の先端の爪部６４ａの動きを制限すると、弾性爪体６４が全く拡開できなくなる。また、制限部６２が弾性爪体６４の根元側のみに当接すると、弾性爪体６４の拡開をほとんど制限できなくなる。そのため制限部６２は弾性爪体６４の中間部分に当接する。 The middle part of the elastic claw body 64 is, for example, the center of the outer surface of the elastic claw body 64. When the restricting portion 62 restricts the movement of the claw portion 64a at the tip of the restricting portion 62, the elastic claw body 64 cannot be expanded at all. Further, when the restricting portion 62 contacts only the base side of the elastic claw body 64, the expansion of the elastic claw body 64 can hardly be restricted. Therefore, the restricting portion 62 abuts on the intermediate portion of the elastic claw body 64.

図９は、第２変形例のフック装置８０の中央断面図である。第２変形例のフック装置８０は、第１変形例のフック装置６０と比べて、弾性爪体８２と制限部８４の形状が異なる。弾性爪体８２は、第１変形例のフック装置６０と比べて逆方向に延出する。 FIG. 9 is a central sectional view of a hook device 80 of a second modification. The hook device 80 of the second modified example is different from the hook device 60 of the first modified example in the shapes of the elastic claw body 82 and the restricting portion 84. The elastic claw body 82 extends in the opposite direction compared to the hook device 60 of the first modification.

弾性爪体８２は、屈曲部４４側で基部４２の裏側壁部５４に連結し、先端に形成された爪部８２ａを有する。爪部８２ａは、挿入孔４６の内向き、つまり表側壁部５２に向かって突き出す。爪部８２ａにより抜け止め部２８の抜き方向の移動を規制する。 The elastic claw body 82 is connected to the back side wall portion 54 of the base portion 42 on the bent portion 44 side, and has a claw portion 82a formed at the tip. The claw portion 82 a protrudes inward of the insertion hole 46, that is, toward the front side wall portion 52. The movement of the retaining portion 28 in the removal direction is restricted by the claw portion 82a.

制限部８４は、弾性爪体８２が拡開した場合に、弾性爪体８２の中間部分に当接して弾性爪体８２の拡開を制限する。 When the elastic claw body 82 is expanded, the restricting portion 84 abuts on an intermediate portion of the elastic claw body 82 and restricts the expansion of the elastic claw body 82.

図１０は、第３変形例のフック部材４０について説明するための図である。図１０（ａ）は、フック部材４０を挿入孔４６側から見た図であり、図１０（ｂ）は、挿入孔４６を形成するための金型１５０の斜視図である。 FIG. 10 is a view for explaining a hook member 40 of a third modified example. 10A is a view of the hook member 40 as viewed from the insertion hole 46 side, and FIG. 10B is a perspective view of a mold 150 for forming the insertion hole 46.

図１０（ａ）に示すように、挿入孔４６の内面には複数の凸部９０が形成される。この凸部９０は、図１０（ｂ）に示す金型１５０にて形成され、挿入孔４６の内面に挿入部２４の挿入方向に沿って延設される。凸部９０は、表側壁部５２および裏側壁部５４にそれぞれ２つずつ形成され、互いに平行に延伸する。 As shown in FIG. 10A, a plurality of convex portions 90 are formed on the inner surface of the insertion hole 46. The convex portion 90 is formed by a mold 150 shown in FIG. 10B and extends along the insertion direction of the insertion portion 24 on the inner surface of the insertion hole 46. Two convex portions 90 are formed on each of the front side wall portion 52 and the rear side wall portion 54 and extend in parallel to each other.

平板状の金型１５０は、表裏の両面に凸部９０を形成するための凹部１５４と、挿入方向先端側に切り欠いて形成され、隆起部５８を形成するための切欠部１５６を有する。金型１５０は、挿入方向先端に向かって先細形状に形成される。これにより図４（ｂ）に示すように挿入孔４６の側部４６ａが傾斜する。また金型１５０は、板幅のみならず板厚も挿入方向先端に向かって先細形状であるため、表側壁部の内面および裏側壁部の内面も開口から奥側に向かって接近するように形成される。金型１５０の先端側に向かって先細にすることで成形する際において金型１５０を容易に抜くことができる。 The plate-shaped mold 150 has a recess 154 for forming the protrusion 90 on both the front and back surfaces, and a notch 156 for forming the raised portion 58, which is formed by cutting out at the distal end side in the insertion direction. The mold 150 is formed in a tapered shape toward the distal end in the insertion direction. Thereby, as shown in FIG.4 (b), the side part 46a of the insertion hole 46 inclines. In addition, since the mold 150 is tapered not only in the plate width but also in the thickness in the insertion direction, the inner surface of the front side wall portion and the inner surface of the back side wall portion are formed so as to approach from the opening toward the back side. Is done. When forming by tapering toward the tip side of the mold 150, the mold 150 can be easily removed.

挿入孔４６に取付部材２０の挿入部２４が挿入される際、凸部９０を押しつぶすように挿入部２４が圧入される。すなわち、表裏に対向する凸部９０の間隔は、挿入部２４の板厚より少しだけ小さい。挿入部２４は、挿入孔４６の内部にて凸部９０に当接する。これにより取付部材２０のガタツキを抑えることができる。挿入孔４６が開口から奥側に向かって先細形状に形成されても、表側壁部５２の凸部と裏側壁部５４の凸部９０の間隔、すなわち、表裏にて対向する凸部９０の間隔は一定である。これにより、凸部９０が無い先細形状の挿入孔４６に挿入部２４を挿入する場合と比べて、挿入部２４を挿入孔４６に容易に押し込むことができる。凸部９０を形成することで、フック部材４０の表側壁部５２および裏側壁部５４を薄くして軽量化でき、材料コストを抑えることができる。また、凸部９０が奥側まで延設されて補強材として機能し、表側壁部５２および裏側壁部５４の強度の低下を抑えることができる。 When the insertion portion 24 of the attachment member 20 is inserted into the insertion hole 46, the insertion portion 24 is press-fitted so as to crush the convex portion 90. That is, the interval between the convex portions 90 facing the front and back is slightly smaller than the thickness of the insertion portion 24. The insertion portion 24 abuts on the convex portion 90 inside the insertion hole 46. Thereby, rattling of the mounting member 20 can be suppressed. Even if the insertion hole 46 is formed in a tapered shape from the opening toward the back side, the distance between the convex part of the front side wall part 52 and the convex part 90 of the back side wall part 54, that is, the distance between the convex parts 90 facing each other on the front and back sides. Is constant. Thereby, compared with the case where the insertion part 24 is inserted in the taper-shaped insertion hole 46 without the convex part 90, the insertion part 24 can be pushed into the insertion hole 46 easily. By forming the convex part 90, the front side wall part 52 and the back side wall part 54 of the hook member 40 can be made thin and lightweight, and material cost can be suppressed. Moreover, the convex part 90 is extended to the back | inner side, it functions as a reinforcing material, and the fall of the intensity | strength of the front side wall part 52 and the back side wall part 54 can be suppressed.
