Description

本発明は、支持部材と、支持部材に取り付けられている挿入部材と、を持つ取付構造体に関する。本発明の取付構造体は、例えば、車両用のエンジンカバー等として使用できる。   The present invention relates to an attachment structure having a support member and an insertion member attached to the support member. The mounting structure of the present invention can be used as, for example, an engine cover for a vehicle.

支持部材と、支持部材に取り付けられている挿入部材と、を持つ取付構造体において、支持部材は、挿入部材と係合する固定部を持つ。図8に示すように、一般的な取付構造体における支持部材200は、基体300と、基体300から延びる固定部400と、を持つ。挿入部材100は、弾性材料からなり、軸方向の略中央部が縮径している。固定部400は、側方に開口する断面C字の枠状をなし、基体300と一体成形されてなる。固定部400のなかで基体300とは逆側の端部には、上底壁401が形成されている。上底壁401は、基体300を成形する一般成形型(図略)の型開き方向(A、B)と交差する方向に延びる。上底壁401には、挿入部材100の縮径した部分がスライド係合するスライド溝402が形成されている。挿入部材100を固定部400に挿入する方向は図8中矢印C方向である。   In an attachment structure having a support member and an insertion member attached to the support member, the support member has a fixing portion that engages with the insertion member. As shown in FIG. 8, the support member 200 in a general mounting structure has a base body 300 and a fixing portion 400 extending from the base body 300. The insertion member 100 is made of an elastic material, and a substantially central portion in the axial direction is reduced in diameter. The fixing portion 400 has a frame shape with a C-shaped cross section that opens to the side, and is formed integrally with the base body 300. An upper bottom wall 401 is formed at the end of the fixed portion 400 opposite to the base 300. The upper bottom wall 401 extends in a direction intersecting with the mold opening direction (A, B) of a general mold (not shown) for molding the base body 300. The upper bottom wall 401 is formed with a slide groove 402 in which a reduced diameter portion of the insertion member 100 is slidably engaged. The direction in which the insertion member 100 is inserted into the fixing portion 400 is the direction of arrow C in FIG.

図8に示す従来の取付構造体において、固定部400には上底壁401が形成されている。そして、上底壁401は一般成形型の型開き方向A、Bと交差する方向に延びる。このため固定部400の内部は、一般成形型の型開き方向A、Bに対してアンダーカット形状となる。したがって、図8に示す従来の取付構造体を成形するための成形型には、固定部400の内部を成形するスライドコア(図略)が必要である。よって、図8に示す取付構造体を成形するための成形型は構造が複雑になり、図8に示す取付構造体は安価に製造できない問題があった。   In the conventional mounting structure shown in FIG. 8, an upper bottom wall 401 is formed on the fixing portion 400. The upper bottom wall 401 extends in a direction intersecting with the mold opening directions A and B of the general mold. For this reason, the inside of the fixing | fixed part 400 becomes an undercut shape with respect to the mold opening directions A and B of a general shaping | molding die. Therefore, the molding die for molding the conventional mounting structure shown in FIG. 8 requires a slide core (not shown) for molding the inside of the fixing portion 400. Therefore, the mold for molding the mounting structure shown in FIG. 8 has a complicated structure, and the mounting structure shown in FIG. 8 cannot be manufactured at a low cost.

また、このスライドコアは、図8中矢印D方向に型開きする。このため、図8に示す取付構造体における、スライドコアの移動領域(図8中二点差線Eで示す領域)は、スライドコアに干渉しない形状にする必要がある。よって、図8に示す従来の取付構造体は、支持部材の形状の自由度に劣る問題もあった。   The slide core is opened in the direction of arrow D in FIG. For this reason, in the mounting structure shown in FIG. 8, the moving region of the slide core (the region indicated by the two-dot chain line E in FIG. 8) needs to have a shape that does not interfere with the slide core. Therefore, the conventional mounting structure shown in FIG. 8 also has a problem that the degree of freedom of the shape of the support member is inferior.

さらに、一般成形型とスライドコアとの境界部分には段差が生じるため、基体300の表面(固定部400とは逆側の面)にヒケが生じる。このため、意匠性に優れた支持部材200を得難い問題もあった。   Furthermore, since a step is generated at the boundary portion between the general mold and the slide core, sink marks are generated on the surface of the base 300 (the surface opposite to the fixed portion 400). For this reason, there also existed a problem that it was difficult to obtain the supporting member 200 excellent in design property.

特許文献1に紹介されている取付構造体における支持部材は、一対の帯条板と、各帯条板の長手方向の2端部に形成されている脚状のサポートリブと、からなる固定部を持つ。各サポートリブは基体(樹脂芯材または積層体)に一体化されている。帯条板と基体の表面との間には隙間が形成されている。また、この取付構造体における挿入部材(スペーサパッド)は、対向する2側面の下端部に、それぞれ、爪状の係合部(アンダーカット部)を持つ。この取付構造体における挿入部材は、一対の帯条板に挟持され、かつ、アンダーカット部が帯条板と基体との隙間に入り込んで帯条板の下面と係合して、支持部材に取り付けられる。   The support member in the mounting structure introduced in Patent Document 1 is a fixed portion including a pair of strip plates and leg-shaped support ribs formed at two ends in the longitudinal direction of each strip plate. have. Each support rib is integrated with a base (resin core material or laminate). A gap is formed between the strip plate and the surface of the substrate. Moreover, the insertion member (spacer pad) in this attachment structure has a claw-like engaging part (undercut part), respectively, at the lower ends of the two opposing side surfaces. The insertion member in this attachment structure is sandwiched between a pair of strip plates, and the undercut portion enters the gap between the strip plate and the base and engages with the lower surface of the strip plate, and is attached to the support member. It is done.

特許文献1に紹介されている取付構造体によると、一般成形型の型開き方向に対する固定部のアンダーカット形状(以下、単に固定部のアンダーカット形状と呼ぶ)を小さくできる。このため、上述したスライドコアの移動領域が小さくなり、形状の自由度が比較的大きな取付構造体を得ることができると考えられる。しかし、特許文献1に紹介されている取付構造体においても、固定部のアンダーカット形状は依然として存在する。このため、特許文献1に紹介されている技術では、上述したように取付構造体を安価に製造できない問題や、意匠性に優れた支持部財を得難い問題を解決できなかった。
特開平10−44775号公報
According to the mounting structure introduced in Patent Document 1, the undercut shape of the fixed portion with respect to the mold opening direction of the general mold (hereinafter simply referred to as the undercut shape of the fixed portion) can be reduced. For this reason, it is considered that the moving structure of the slide core described above can be reduced, and an attachment structure having a relatively large shape freedom can be obtained. However, even in the mounting structure introduced in Patent Document 1, the undercut shape of the fixed portion still exists. For this reason, the technique introduced in Patent Document 1 cannot solve the problem that the mounting structure cannot be manufactured at a low cost as described above, and the problem that it is difficult to obtain a support part good in design.
Japanese Patent Laid-Open No. 10-44775

本発明は上記事情に鑑みて成されたものであり、安価に製造でき、形状の自由度と意匠性とに優れる取付構造体を提供することを目的とする。   The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an attachment structure that can be manufactured at low cost and is excellent in shape flexibility and design.

上記課題を解決する本発明の取付構造体は、基体と、基体から延び基体の逆方向に開口する中空の固定部と、が一体成形されてなる樹脂製の支持部材と、少なくとも一部が固定部の内部に挿入されている挿入部材と、を持ち、固定部は、基体側の内部に形成されている固定側第1係合部と、開口側の内部に形成されている固定側第2係合部と、を持ち、挿入部材は、弾性材料からなる変形部と、変形部の一端側に形成されている挿入側第1係合部と、変形部の他端側に形成されている挿入側第2係合部と、を持ち、支持部材と挿入部材とは、変形部が弾性的にねじれ変形し、固定側第1係合部と挿入側第1係合部とが係合して、固定側第1係合部が変形部におけるねじれ変形の中心軸を中心とする挿入側第1係合部の回転に干渉し、固定側第2係合部と挿入側第2係合部とが係合して、固定側第2係合部が変形部におけるねじれ変形の中心軸を中心とする挿入側第2係合部の回転に干渉している状態で取り付けられていることを特徴とする。   The mounting structure of the present invention that solves the above-described problem is a resin support member in which a base and a hollow fixing portion that extends from the base and opens in the opposite direction of the base are integrally formed, and at least a part is fixed An insertion member inserted into the inside of the part, and the fixing part includes a first fixing side engaging part formed inside the base and a second fixing side formed inside the opening side. And an insertion member is formed on the other end side of the deformation portion, the insertion side first engagement portion formed on one end side of the deformation portion, and the deformation member made of an elastic material. An insertion-side second engagement portion, and the support member and the insertion member are such that the deformable portion is elastically twisted and the fixed-side first engagement portion and the insertion-side first engagement portion are engaged. The fixed-side first engaging portion interferes with the rotation of the insertion-side first engaging portion about the central axis of torsional deformation in the deforming portion, and the fixed-side first engaging portion The engagement portion and the insertion-side second engagement portion are engaged, and the fixed-side second engagement portion interferes with the rotation of the insertion-side second engagement portion about the central axis of torsional deformation in the deformation portion. It is attached in the state which is attached.

本発明の取付構造体は、下記の(1)〜(2)の少なくとも一つを備えるのが好ましい。
(1)上記変形部は、上記挿入側第1係合部および上記挿入側第2係合部よりも小径である。
(2)上記固定部は角筒状をなし、上記挿入側第1係合部および上記挿入側第2係合部は角柱状をなす。
The mounting structure of the present invention preferably includes at least one of the following (1) to (2).
(1) The deformation portion has a smaller diameter than the insertion side first engagement portion and the insertion side second engagement portion.
(2) The fixing portion has a rectangular tube shape, and the insertion side first engagement portion and the insertion side second engagement portion have a prism shape.

本発明の取付構造体における支持部材を成形するための成形型には、スライドコアが不要になる。これは、以下の理由による。   The molding die for molding the support member in the mounting structure of the present invention does not require a slide core. This is due to the following reason.

支持部材(固定部)に取り付けられた挿入部材において、変形部は弾性的にねじれ変形した状態にある。このため挿入側第1係合部は、変形部の弾性力によって、変形部におけるねじれ変形の中心軸(以下、ねじれ中心軸と呼ぶ)を中心として固定側第1係合部に対して回転しようとする。また、挿入側第2係合部はねじれ中心軸を中心として固定側第1係合部に対して回転しようとする。   In the insertion member attached to the support member (fixed portion), the deformable portion is elastically twisted and deformed. For this reason, the insertion-side first engagement portion is rotated relative to the fixed-side first engagement portion about the central axis of the torsional deformation (hereinafter referred to as the torsion central axis) in the deformation portion by the elastic force of the deformation portion. And Further, the insertion-side second engagement portion tends to rotate with respect to the fixed-side first engagement portion about the torsional central axis.

しかし、このとき固定側第1係合部が挿入側第1係合部と係合して、挿入側第1係合部の回転に干渉する。また、固定側第2係合部が挿入側第2係合部と係合して、挿入側第2係合部の回転に干渉する。換言すると、変形部の弾性によって、挿入側第1係合部は固定側第1係合部に押し付けられ、挿入側第2係合部は固定側第2係合部に押し付けられる。このため挿入部材は、挿入側第1係合部の固定側第1係合部に対する面圧と、挿入側第2係合部の固定側第2係合部に対する面圧と、によって固定部に固定される。したがって、本発明の取付構造体によると、固定部にアンダーカット形状を設けなくても、支持部材から挿入部材が脱離し難くなる。すなわち本発明の取付構造体は、固定部のアンダーカット形状によって挿入部材の脱離を防止するのではなく、挿入部材の固定部に対する面圧によって挿入部材の脱離を防止する。このため、スライドコアのない成形型で支持部材を成形できる。よって、本発明の取付構造体は安価に製造でき、かつ、形状の自由度と意匠性とに優れる。   However, at this time, the fixed-side first engagement portion engages with the insertion-side first engagement portion, and interferes with the rotation of the insertion-side first engagement portion. Further, the fixed-side second engagement portion engages with the insertion-side second engagement portion and interferes with the rotation of the insertion-side second engagement portion. In other words, due to the elasticity of the deformable portion, the insertion side first engagement portion is pressed against the fixed side first engagement portion, and the insertion side second engagement portion is pressed against the fixed side second engagement portion. For this reason, the insertion member is fixed to the fixed portion by the surface pressure of the insertion side first engagement portion with respect to the fixed side first engagement portion and the surface pressure of the insertion side second engagement portion with respect to the fixed side second engagement portion. Fixed. Therefore, according to the mounting structure of the present invention, it is difficult for the insertion member to be detached from the support member without providing an undercut shape in the fixing portion. That is, the mounting structure of the present invention does not prevent the insertion member from being detached by the undercut shape of the fixing portion, but prevents the insertion member from being detached by the surface pressure with respect to the fixing portion of the insertion member. For this reason, a support member can be shape | molded with the shaping | molding die without a slide core. Therefore, the mounting structure of the present invention can be manufactured at a low cost, and is excellent in shape flexibility and design.

上記(1)を備える本発明の取付構造体は、変形部が挿入側第1係合部および挿入側第2係合部よりも小径である。このため、変形部がねじれ変形し易くなり、挿入部材を支持部材に取り付ける作業が容易になる。また、挿入側第1係合部および挿入側第2係合部が変形部よりも大径であるため、挿入側第1係合部が固定側第1係合部と強固に係合できる程度に変形し難く、挿入側第2係合部が固定側第2係合部と強固に係合できる程度に変形し難くなる。このため挿入部材は、より一層、支持部材から脱離し難くなる。   In the mounting structure of the present invention having the above (1), the deforming portion has a smaller diameter than the insertion side first engagement portion and the insertion side second engagement portion. For this reason, a deformation | transformation part becomes torsionally deformed easily and the operation | work which attaches an insertion member to a support member becomes easy. In addition, since the insertion side first engagement portion and the insertion side second engagement portion have a larger diameter than the deformation portion, the insertion side first engagement portion can be firmly engaged with the fixed side first engagement portion. It is difficult to be deformed to such an extent that the insertion-side second engagement portion can be firmly engaged with the fixed-side second engagement portion. For this reason, the insertion member becomes more difficult to be detached from the support member.

上記(2)を備える本発明の取付構造体は、より一層安価に製造できる。上記(2)を備える本発明の取付構造体は固定部を単純な形状にできることから、支持部材を成形し易くなるためである。   The mounting structure of the present invention having the above (2) can be manufactured at a lower cost. This is because the mounting structure of the present invention having the above (2) can easily form the support member because the fixing portion can be formed in a simple shape.

以下、本発明の取付構造体を図面を基に説明する。   Hereinafter, the mounting structure of the present invention will be described with reference to the drawings.

The principal part expansion perspective view which represents typically the attachment structure of Example 1 is shown to FIGS. 1 shows the insertion member and the support member before integration, and FIG. 2 shows the insertion member and the support member after integration. Hereinafter, the term “upper and lower” refers to the upper and lower sides shown in FIG.

実施例1の取付構造体は、挿入部材1と支持部材2とを持つ。実施例1の取付構造体はエンジンカバーであり、支持部材2はエンジンカバー本体である。挿入部材1はエンジンの一部を構成するシリンダヘッドカバー(図略)に支持部材2(エンジンカバー本体)を取り付けるためのグロメットである。   The mounting structure of the first embodiment has an insertion member 1 and a support member 2. The mounting structure of Example 1 is an engine cover, and the support member 2 is an engine cover body. The insertion member 1 is a grommet for attaching a support member 2 (engine cover main body) to a cylinder head cover (not shown) constituting a part of the engine.

挿入部材1は、図1に示すように、変形部10と、挿入側第1係合部11と、挿入側第2係合部12と、ピン係合部13と、からなる。実施例1の取付構造体における挿入部材1は、全体が弾性材料の一種であるゴムからなる。   As shown in FIG. 1, the insertion member 1 includes a deformable portion 10, an insertion side first engagement portion 11, an insertion side second engagement portion 12, and a pin engagement portion 13. The insertion member 1 in the mounting structure of Embodiment 1 is made of rubber, which is a kind of elastic material as a whole.

変形部10は略円柱状をなす。挿入側第1係合部11は略角柱状をなし、変形部10の軸方向の一端側に形成されている。挿入側第2係合部12は挿入側第1係合部11よりも軸方向長さが短い略角柱状をなし、変形部10の軸方向の他端側に形成されている。挿入側第1係合部11と挿入側第2係合部12とは、互いに、変形部10の軸方向に離間し、変形部10の中心軸を中心として所定角度回転した位置で変形部10に一体化されている。変形部10は、挿入側第1係合部11および挿入側第2係合部12よりも小径である。ピン係合部13は、略円柱状をなす。ピン係合部13は、挿入側第2係合部12を挟んだ変形部10の逆側(図1における挿入側第2係合部12の上側)に形成されている。ピン係合部13には、シリンダヘッドカバーに一体形成されている取付ピン(図略)と係合する孔状のピン保持孔130が形成されている。   The deformable portion 10 has a substantially cylindrical shape. The insertion side first engagement portion 11 has a substantially prismatic shape, and is formed on one end side in the axial direction of the deformation portion 10. The insertion-side second engagement portion 12 has a substantially prismatic shape that is shorter in the axial direction than the insertion-side first engagement portion 11, and is formed on the other end side of the deformation portion 10 in the axial direction. The insertion side first engagement part 11 and the insertion side second engagement part 12 are spaced apart from each other in the axial direction of the deformation part 10 and are rotated at a predetermined angle about the central axis of the deformation part 10. Is integrated. The deformable portion 10 has a smaller diameter than the insertion side first engagement portion 11 and the insertion side second engagement portion 12. The pin engaging portion 13 has a substantially cylindrical shape. The pin engaging portion 13 is formed on the opposite side of the deformable portion 10 across the insertion side second engagement portion 12 (upper side of the insertion side second engagement portion 12 in FIG. 1). The pin engaging portion 13 is formed with a hole-shaped pin holding hole 130 that engages with a mounting pin (not shown) formed integrally with the cylinder head cover.

支持部材2は、樹脂材料の一種であるナイロンからなる。図1に示すように、支持部材2は、基体3と、基体に一体成形されている固定部4と、を持つ。基体3は略板状をなす。固定部4は角筒状をなし、軸方向の一端側が基体3に一体化されている。また、固定部4の軸方向の他端側は開口している。固定部4の内径は一定である。固定部4の肉厚は基体3側が厚く、開口40側が薄くなっている。実施例1の取付構造体においては、固定部4の内周面のなかで基体3側の部分が固定側第1係合部41となる。また、固定部4の内周面のなかで開口40側の部分が固定側第2係合部42となる。   The support member 2 is made of nylon which is a kind of resin material. As shown in FIG. 1, the support member 2 has a base 3 and a fixing portion 4 integrally formed with the base. The substrate 3 has a substantially plate shape. The fixed portion 4 has a rectangular tube shape, and one end side in the axial direction is integrated with the base 3. Further, the other end side in the axial direction of the fixed portion 4 is opened. The inner diameter of the fixed part 4 is constant. The thickness of the fixing portion 4 is thick on the base 3 side and thin on the opening 40 side. In the mounting structure of the first embodiment, the portion on the base 3 side in the inner peripheral surface of the fixed portion 4 becomes the fixed-side first engaging portion 41. Further, the portion on the opening 40 side in the inner peripheral surface of the fixed portion 4 becomes the fixed-side second engaging portion 42.

実施例1の取付構造体における挿入部材1を、支持部材2に取り付ける手順は以下のとおりである。   The procedure for attaching the insertion member 1 in the attachment structure of the first embodiment to the support member 2 is as follows.

先ず、挿入部材1の挿入側第1係合部11を固定部4の開口40に対面させて、図1中矢印aに示すように、挿入側第1係合部11および変形部10を固定部4に挿入する。このとき、挿入側第1係合部11と固定側第1係合部41とは、軸方向の一部で係合する。詳しくは、挿入側第1係合部11のなかで図1中下側の部分と、固定側第1係合部41のなかで図1中上側の部分とが係合する。次いで、図1中矢印bに示すように、挿入側第2係合部12を変形部10の中心軸を中心として回転させる。このとき、挿入側第1係合部11は固定側第1係合部41と係合しているため、挿入側第2係合部12を回転させると、変形部10が弾性的にねじれ変形する。なお、実施例1の取付構造体においては、変形部10のねじれ中心軸Lは、変形部10の中心軸と一致している。   First, the insertion side first engagement portion 11 of the insertion member 1 is made to face the opening 40 of the fixing portion 4, and the insertion side first engagement portion 11 and the deformation portion 10 are fixed as shown by an arrow a in FIG. Insert into part 4. At this time, the insertion-side first engagement portion 11 and the fixed-side first engagement portion 41 engage with each other in a part in the axial direction. Specifically, the lower portion in FIG. 1 in the insertion side first engagement portion 11 and the upper portion in FIG. 1 in the fixed side first engagement portion 41 are engaged. Next, as shown by an arrow b in FIG. 1, the insertion-side second engagement portion 12 is rotated about the central axis of the deformation portion 10. At this time, since the insertion-side first engagement portion 11 is engaged with the fixed-side first engagement portion 41, when the insertion-side second engagement portion 12 is rotated, the deformable portion 10 is elastically twisted and deformed. To do. In the mounting structure according to the first embodiment, the torsional central axis L of the deformable portion 10 coincides with the central axis of the deformable portion 10.

この状態で、挿入部材1をさらに固定部4に挿入すると、挿入側第1係合部11と固定側第1係合部41とが軸方向の全体で係合する(図2)。このとき挿入側第2係合部12は、固定部4の内部に収容され、固定側第2係合部42と係合する。ピン係合部13は固定部4の外部に配される。   When the insertion member 1 is further inserted into the fixing portion 4 in this state, the insertion-side first engagement portion 11 and the fixed-side first engagement portion 41 engage with each other in the axial direction (FIG. 2). At this time, the insertion-side second engagement portion 12 is housed inside the fixed portion 4 and engages with the fixed-side second engagement portion 42. The pin engaging portion 13 is disposed outside the fixed portion 4.

ところで、図2に示す状態において、変形部10は、弾性的にねじれ変形したままであるため、もとの形状に戻ろうとする。したがって、この変形部10の弾力によって、挿入側第1係合部11と挿入側第2係合部12とは、ねじれ中心軸Lを中心として、互いに逆方向に回転しようとする。すなわち、挿入側第1係合部11はねじれ中心軸Lを中心に図2中c方向に回転しようとする。挿入側第2係合部12は、ねじれ中心軸Lを中心に図2中d方向に回転しようとする。   By the way, in the state shown in FIG. 2, since the deformation | transformation part 10 has continued elastically torsionally deformed, it tries to return to the original shape. Therefore, due to the elasticity of the deformable portion 10, the insertion-side first engagement portion 11 and the insertion-side second engagement portion 12 try to rotate in opposite directions around the torsional center axis L. That is, the insertion-side first engagement portion 11 tends to rotate in the direction c in FIG. The insertion-side second engagement portion 12 tends to rotate in the direction d in FIG.

しかし、固定側第1係合部41は、挿入側第1係合部11と係合して、ねじれ中心軸Lを中心とする挿入側第1係合部11の回転に干渉する。また、固定側第2係合部42は、挿入側第2係合部12と係合して、ねじれ中心軸Lを中心とする挿入側第2係合部12の回転に干渉する。   However, the fixed first engagement portion 41 engages with the insertion side first engagement portion 11 and interferes with the rotation of the insertion side first engagement portion 11 about the torsion central axis L. Further, the fixed-side second engagement portion 42 engages with the insertion-side second engagement portion 12 and interferes with the rotation of the insertion-side second engagement portion 12 about the torsion central axis L.

すなわち、挿入側第1係合部11および挿入側第2係合部12の径方向断面(外周側)は、それぞれ、「ねじれ中心軸Lを中心とする正円」以外の形状である。固定側第1係合部41および固定側第2係合部42の径方向断面(内周側)もまた、「ねじれ中心軸Lを中心とする正円」以外の形状である。このため、ねじれ中心軸Lを中心とする挿入側第1係合部11の回転は、固定側第1係合部41によって干渉される。ねじれ中心軸Lを中心とする挿入側第2係合部12の回転は、固定側第2係合部42によって干渉される。   That is, the radial cross sections (outer peripheral sides) of the insertion-side first engagement portion 11 and the insertion-side second engagement portion 12 have shapes other than “a perfect circle centered on the torsion central axis L”, respectively. The radial cross section (inner peripheral side) of the fixed side first engaging portion 41 and the fixed side second engaging portion 42 also has a shape other than “a perfect circle centered on the torsion central axis L”. For this reason, the rotation of the insertion side first engagement portion 11 around the torsional central axis L is interfered by the fixed side first engagement portion 41. The rotation of the insertion-side second engagement portion 12 around the twist center axis L is interfered by the fixed-side second engagement portion 42.

このため、挿入側第1係合部11は固定側第1係合部41に押し付けられ、挿入側第2係合部12は固定側第2係合部42に押し付けられる。したがって挿入部材1は、挿入側第1係合部11の固定側第1係合部41に対する面圧と、挿入側第2係合部12の固定側第2係合部42に対する面圧と、によって固定部4に固定される。したがって、挿入部材1の脱離方向(図1中上下方向)の動きが規制される。よって、実施例1の取付構造体における挿入部材1は、支持部材2から脱離し難い。   For this reason, the insertion side first engagement part 11 is pressed against the fixed side first engagement part 41, and the insertion side second engagement part 12 is pressed against the fixed side second engagement part 42. Accordingly, the insertion member 1 has a surface pressure of the insertion side first engagement portion 11 with respect to the fixed side first engagement portion 41, a surface pressure of the insertion side second engagement portion 12 with respect to the fixed side second engagement portion 42, and To be fixed to the fixing part 4. Therefore, the movement of the insertion member 1 in the detaching direction (vertical direction in FIG. 1) is restricted. Therefore, the insertion member 1 in the mounting structure of Example 1 is difficult to be detached from the support member 2.

実施例1の取付構造体によると、固定側第1係合部41は挿入側第1係合部11のねじれ中心軸Lを中心とする回転に干渉すればよく、固定側第2係合部42は挿入側第2係合部12のねじれ中心軸Lを中心とする回転に干渉すればよい。このため、実施例1の取付構造体では、固定部4のアンダーカット形状が不要になる。よって、基体3と固定部4とを持つ支持部材2を、スライドコアのない成形型で一体成形できる。よって、実施例1の取付構造体は安価に製造できる。   According to the mounting structure of the first embodiment, the fixed-side first engagement portion 41 only has to interfere with the rotation about the torsional central axis L of the insertion-side first engagement portion 11. 42 may interfere with the rotation about the torsional central axis L of the insertion-side second engagement portion 12. For this reason, in the attachment structure of Example 1, the undercut shape of the fixing | fixed part 4 becomes unnecessary. Therefore, the support member 2 having the base body 3 and the fixing portion 4 can be integrally formed with a molding die having no slide core. Therefore, the mounting structure of Example 1 can be manufactured at low cost.

また、スライドコアのない成形型で基体3と固定部4とを一体成形することで、支持部材2にスライドコアの移動領域を設ける必要がなくなる。よって実施例1の取付構造体は、支持部材2の形状の自由度に優れる。   Further, by integrally molding the base body 3 and the fixed portion 4 with a molding die having no slide core, it is not necessary to provide a movement area for the slide core in the support member 2. Therefore, the mounting structure of Example 1 is excellent in the degree of freedom of the shape of the support member 2.

さらに、スライドコアのない成形型で基体3と固定部4とを一体成形することで、一般成形型とスライドコアとの境界部分がなくなる。このため、従来の取付構造体においてこの境界部分に生じていた段差がなくなる。よって、実施例1の取付構造体は、支持部材2のヒケがなくなり、意匠性に優れる。   Furthermore, by integrally molding the base body 3 and the fixing portion 4 with a molding die having no slide core, the boundary portion between the general molding die and the slide core is eliminated. For this reason, the level | step difference which had arisen in this boundary part in the conventional attachment structure is lose | eliminated. Therefore, the mounting structure of Example 1 is free from sink marks of the support member 2 and is excellent in design.

また、実施例1の取付構造体においては、変形部10は挿入側第1係合部11および挿入側第2係合部12よりも小径であり、ねじれ変形し易い。このため、実施例1の取付構造体によると、挿入部材1を支持部材2に取り付ける作業が容易になる。また、挿入側第1係合部11および挿入側第2係合部12は変形部10よりも大径であり、変形部10に比べて変形し難い。このため、実施例1の取付構造体によると、挿入側第1係合部11と固定側第1係合部41とを強固に係合させることができ、かつ、挿入側第2係合部12と固定側第2係合部42とを強固に係合させることができる。   Moreover, in the attachment structure of Example 1, the deformation | transformation part 10 is smaller diameter than the insertion side 1st engagement part 11 and the insertion side 2nd engagement part 12, and it is easy to torsionally deform. For this reason, according to the attachment structure of Example 1, the operation | work which attaches the insertion member 1 to the support member 2 becomes easy. Further, the insertion side first engagement portion 11 and the insertion side second engagement portion 12 have a larger diameter than the deformation portion 10, and are less likely to be deformed than the deformation portion 10. For this reason, according to the attachment structure of Example 1, the insertion side first engagement part 11 and the fixed side first engagement part 41 can be firmly engaged, and the insertion side second engagement part. 12 and the fixed-side second engagement portion 42 can be firmly engaged.

さらに、実施例1の取付構造体における支持部材2は、固定部4が単純な形状(角筒状)をなすために容易かつ安価に製造できる。   Furthermore, the support member 2 in the mounting structure of Embodiment 1 can be easily and inexpensively manufactured because the fixing portion 4 has a simple shape (square tube shape).

ところで、本発明の取付構造体からなるエンジンカバーをエンジンに取り付ける際には、図略の取付ピンを挿入部材1のピン係合部13に差し込む。図8に示す従来のエンジンカバーにおいては、ピン係合部13が固定部4の内部に配されるため、ピン係合部13に差し込まれた取付ピン(図略)もまた、固定部4の内部に配される。このため、図8に示す従来のエンジンカバーによると、エンジンの振動が取付ピンを介して支持部材2に伝達し易い。支持部材2は樹脂製であり、比較的硬質であるために、エンジンの振動が支持部材2に伝達すると、異音が発生する場合がある。一方、実施例1の取付構造体では、ピン係合部13は固定部4の外部に配され、ピン係合部13に差し込まれた取付ピンもまた固定部4の外部(すなわち、固定部4と軸方向に離間した位置)に配される。このため、実施例1の取付構造体によると、エンジンの振動が支持部材2に伝わり難く、異音が発生し難い利点もある。   By the way, when the engine cover made of the mounting structure of the present invention is mounted on the engine, a mounting pin (not shown) is inserted into the pin engaging portion 13 of the insertion member 1. In the conventional engine cover shown in FIG. 8, since the pin engaging portion 13 is disposed inside the fixing portion 4, an attachment pin (not shown) inserted into the pin engaging portion 13 is also attached to the fixing portion 4. Arranged inside. For this reason, according to the conventional engine cover shown in FIG. 8, the vibration of the engine is easily transmitted to the support member 2 via the mounting pin. Since the support member 2 is made of resin and is relatively hard, abnormal noise may be generated when engine vibration is transmitted to the support member 2. On the other hand, in the mounting structure of the first embodiment, the pin engaging portion 13 is arranged outside the fixing portion 4, and the mounting pin inserted into the pin engaging portion 13 is also outside the fixing portion 4 (that is, the fixing portion 4). And a position separated in the axial direction). For this reason, according to the attachment structure of Example 1, there is also an advantage that the vibration of the engine is not easily transmitted to the support member 2 and abnormal noise is hardly generated.

実施例1の取付構造体における支持部材2はナイロンからなるが、本発明の取付構造体における支持部材の材料としては、PP(ポリプロピレン)等の他の樹脂材料を選択しても良い。   Although the support member 2 in the mounting structure of Example 1 is made of nylon, other resin materials such as PP (polypropylene) may be selected as the material of the support member in the mounting structure of the present invention.

(実施例2)
実施例2の取付構造体は、挿入側第1係合部の形状と固定側第1係合部の形状以外は実施例1の取付構造体と同じである。実施例2の取付構造体を模式的に表す要部拡大斜視図を図3〜5に示す。なお、図3は一体化する前の挿入部材および支持部材を表し、図5は一体化した後の挿入部材および支持部材を表す。図4は一体化している途中の挿入部材および支持部材を表す。
(Example 2)
The attachment structure of Example 2 is the same as the attachment structure of Example 1 except for the shape of the insertion side first engagement portion and the shape of the fixed side first engagement portion. The principal part expansion perspective view which represents typically the attachment structure of Example 2 is shown in FIGS. 3 shows the insertion member and the support member before integration, and FIG. 5 shows the insertion member and the support member after integration. FIG. 4 shows the insertion member and the support member in the middle of integration.

図3に示すように、実施例2の取付構造体における固定部4は、角筒状の外枠部45と、外枠部45の内部に形成されている断面略十字状のリブ46と、からなる。実施例2の取付構造体における固定側第1係合部41は、このリブ46からなる。外枠部45は、実施例1の取付構造体における固定部4と同形状である。固定側第2係合部42は、外枠部45の内周面のなかで開口40側の部分からなる。   As shown in FIG. 3, the fixing portion 4 in the mounting structure of the second embodiment includes a rectangular tube-shaped outer frame portion 45, a rib 46 having a substantially cross-shaped cross section formed inside the outer frame portion 45, and Consists of. The fixed first engaging portion 41 in the mounting structure of the second embodiment is formed of the rib 46. The outer frame portion 45 has the same shape as the fixing portion 4 in the mounting structure of the first embodiment. The fixed-side second engagement portion 42 is a portion on the opening 40 side in the inner peripheral surface of the outer frame portion 45.

実施例2の取付構造体における挿入部材1は、実施例1の取付構造体と略同形のピン係合部13と挿入側第2係合部12とをもつ。挿入部材1のなかで、挿入側第2係合部12を挟んでピン係合部13と逆側の部分は、略円柱状に延びている。この略円柱状の部分のなかで、挿入側第2係合部12と逆側の端部には、断面略十字状のスリット16が形成されている。実施例2の取付構造体における挿入側第1係合部11は、このスリット16からなる。また、実施例2の取付構造体における変形部10は、この略円柱状の部分のなかで、挿入側第1係合部11よりも挿入側第2係合部12側の部分からなる。実施例2の取付構造体において、挿入側第1係合部11は凹状をなし、固定側第1係合部41は凸状をなす。   The insertion member 1 in the mounting structure of the second embodiment has a pin engaging portion 13 and an insertion-side second engaging portion 12 that are substantially the same shape as the mounting structure of the first embodiment. In the insertion member 1, the portion on the opposite side of the pin engagement portion 13 across the insertion side second engagement portion 12 extends in a substantially columnar shape. In this substantially cylindrical portion, a slit 16 having a substantially cross-shaped cross section is formed at the end opposite to the insertion-side second engagement portion 12. The insertion side first engagement portion 11 in the mounting structure of the second embodiment includes the slit 16. Moreover, the deformation | transformation part 10 in the attachment structure of Example 2 consists of a part on the insertion side 2nd engagement part 12 side rather than the insertion side 1st engagement part 11 in this substantially cylindrical part. In the mounting structure according to the second embodiment, the insertion-side first engagement portion 11 has a concave shape, and the fixed-side first engagement portion 41 has a convex shape.

実施例2の取付構造体における挿入部材1を、支持部材2に取り付ける手順は以下のとおりである。   The procedure for attaching the insertion member 1 in the attachment structure of Example 2 to the support member 2 is as follows.

先ず、図3に示すように、挿入部材1の挿入側第1係合部11を固定部4の開口40に対面させて、挿入側第1係合部11および変形部10を外枠部45に挿入する。このとき、挿入側第1係合部11と固定側第1係合部41とは、軸方向の一部で係合する(図4)。   First, as shown in FIG. 3, the insertion-side first engagement portion 11 of the insertion member 1 faces the opening 40 of the fixing portion 4, and the insertion-side first engagement portion 11 and the deformable portion 10 are connected to the outer frame portion 45. Insert into. At this time, the insertion-side first engagement portion 11 and the fixed-side first engagement portion 41 engage with each other in a part in the axial direction (FIG. 4).

次いで、挿入側第2係合部12を変形部10の中心軸を中心として回転させ、変形部10を弾性的にねじれ変形させる。そして、挿入部材1をさらに外枠部45に挿入する。すると、挿入側第1係合部11が固定側第1係合部41とが軸方向の全体で係合し、挿入側第2係合部12が固定側第2係合部42と係合して、挿入部材1が固定部4に取り付けられる(図5)。   Next, the insertion-side second engagement portion 12 is rotated about the central axis of the deformation portion 10 to elastically twist and deform the deformation portion 10. Then, the insertion member 1 is further inserted into the outer frame portion 45. Then, the insertion-side first engagement portion 11 engages with the fixed-side first engagement portion 41 in the entire axial direction, and the insertion-side second engagement portion 12 engages with the fixed-side second engagement portion 42. And the insertion member 1 is attached to the fixing | fixed part 4 (FIG. 5).

このとき、変形部10はねじれ変形したままであるため、変形部10の弾力によって、挿入側第1係合部11は固定側第1係合部41に押し付けられ、挿入側第2係合部12は固定側第2係合部42に押し付けられる。よって、挿入部材1は、挿入側第1係合部11の固定側第1係合部41に対する面圧と、挿入側第2係合部12の固定側第2係合部42に対する面圧と、によって固定部4に固定される。よって、挿入部材1の脱離方向の動きが規制される。よって、実施例2の取付構造体における挿入部材1は、支持部材2から脱離し難い。   At this time, since the deformable portion 10 remains torsionally deformed, the insertion-side first engagement portion 11 is pressed against the fixed-side first engagement portion 41 by the elasticity of the deformation portion 10, and the insertion-side second engagement portion. 12 is pressed against the fixed second engaging portion 42. Therefore, the insertion member 1 has a surface pressure of the insertion side first engagement portion 11 with respect to the fixed side first engagement portion 41 and a surface pressure of the insertion side second engagement portion 12 with respect to the fixed side second engagement portion 42. To be fixed to the fixing part 4. Therefore, the movement of the insertion member 1 in the removal direction is restricted. Therefore, the insertion member 1 in the mounting structure of Example 2 is not easily detached from the support member 2.

実施例2の取付構造体は、実施例1の取付構造体と同様に、固定部4のアンダーカット形状が不要になることから、スライドコアのない成形型で支持部材2を成形できる。すなわち、実施例2の取付構造体もまた、安価に製造でき、かつ、形状の自由度と意匠性とに優れる。   Since the attachment structure of the second embodiment does not require the undercut shape of the fixing portion 4 in the same manner as the attachment structure of the first embodiment, the support member 2 can be formed using a mold without a slide core. That is, the mounting structure of Example 2 can also be manufactured at a low cost, and is excellent in shape flexibility and design.

なお、実施例2の取付構造体における固定側第1係合部41(すなわちリブ46)と挿入側第2係合部12(すなわちスリット16)とはともに断面略十字状をなすが、上述したように「ねじれ中心軸を中心とする正円」以外の形状であればよく、例えば、断面略一文字状などの他の形状であっても良い。   It should be noted that the fixed-side first engagement portion 41 (that is, the rib 46) and the insertion-side second engagement portion 12 (that is, the slit 16) in the mounting structure according to the second embodiment are substantially cross-shaped in cross section. Thus, any shape other than “a perfect circle centered on the torsional central axis” may be used. For example, another shape such as a substantially single character in cross section may be used.

(実施例3)
実施例3の取付構造体は、挿入部材および固定部の形状以外は実施例1の取付構造体と同じである。実施例3の取付構造体を模式的に表す要部拡大斜視図を図6〜7に示す。なお、図6は一体化する前の挿入部材および支持部材を表し、図7は一体化した後の挿入部材および支持部材を表す。
(Example 3)
The attachment structure of Example 3 is the same as the attachment structure of Example 1 except for the shapes of the insertion member and the fixing portion. The principal part expansion perspective view which represents typically the attachment structure of Example 3 is shown in FIGS. 6 shows the insertion member and the support member before integration, and FIG. 7 shows the insertion member and the support member after integration.

実施例3の取付構造体における挿入部材1は、図6に示すように、角柱を軸方向にねじった形状をなす。挿入側第1係合部11は、挿入部材1の軸方向の一端部からなる。ピン係合部13は、挿入部材1の軸方向の他端部からなる。挿入側第2係合部12は、挿入部材1のなかでピン係合部13に隣接する部分からなる。変形部10は、挿入部材1のなかで挿入側第1係合部11に隣接する部分からなる。固定部4は角筒状をなす。固定部4の軸方向の一端側は基体3に一体化されている。固定部4の軸方向の他端側は開口している。固定部4の内径は一定である。また、固定部4の肉厚は基体3側が厚く、開口40側が薄い。実施例3の取付構造体においては、固定部4の内周面のなかで基体3側の部分が固定側第1係合部41となる。また、固定部4の内周面のなかで開口40側の部分が固定側第2係合部42となる。   As shown in FIG. 6, the insertion member 1 in the mounting structure of Example 3 has a shape in which a prism is twisted in the axial direction. The insertion side first engagement portion 11 is composed of one end portion of the insertion member 1 in the axial direction. The pin engaging portion 13 is composed of the other end portion of the insertion member 1 in the axial direction. The insertion-side second engagement portion 12 includes a portion adjacent to the pin engagement portion 13 in the insertion member 1. The deformable portion 10 includes a portion adjacent to the insertion side first engagement portion 11 in the insertion member 1. The fixing part 4 has a rectangular tube shape. One end side in the axial direction of the fixed portion 4 is integrated with the base 3. The other end side of the fixed portion 4 in the axial direction is open. The inner diameter of the fixed part 4 is constant. Further, the thickness of the fixing portion 4 is thick on the base 3 side and thin on the opening 40 side. In the mounting structure of the third embodiment, the portion on the base 3 side in the inner peripheral surface of the fixing portion 4 becomes the fixing-side first engagement portion 41. Further, the portion on the opening 40 side in the inner peripheral surface of the fixed portion 4 becomes the fixed-side second engaging portion 42.

実施例3の取付構造体における挿入部材1を支持部材2に取り付ける手順は、以下の通りである。   The procedure for attaching the insertion member 1 to the support member 2 in the attachment structure of Example 3 is as follows.

先ず、挿入側第1係合部11および変形部10を固定部4に挿入して、挿入側第1係合部11と固定側第1係合部41とを軸方向の一部で係合させる。次いで、挿入側第2係合部12を、変形部10の中心軸を中心として回転させつつ、挿入部材1をさらに固定部4に挿入する。すると、挿入側第1係合部11と固定側第1係合部41とが軸方向の全体で係合し、挿入側第2係合部12が固定側第2係合部42と係合して、挿入部材1が固定部4に取り付けられる(図7)。挿入部材1を固定部4に取り付けると、変形部10の弾力によって、挿入側第1係合部11は固定側第1係合部41に押し付けられ、挿入側第2係合部12は固定側第2係合部42に押し付けられる。よって、挿入部材1は固定部4に固定される。   First, the insertion-side first engagement portion 11 and the deformable portion 10 are inserted into the fixed portion 4, and the insertion-side first engagement portion 11 and the fixed-side first engagement portion 41 are partially engaged in the axial direction. Let Next, the insertion member 1 is further inserted into the fixing portion 4 while the insertion-side second engagement portion 12 is rotated about the central axis of the deformation portion 10. Then, the insertion-side first engagement portion 11 and the fixed-side first engagement portion 41 engage in the entirety in the axial direction, and the insertion-side second engagement portion 12 engages with the fixed-side second engagement portion 42. And the insertion member 1 is attached to the fixing | fixed part 4 (FIG. 7). When the insertion member 1 is attached to the fixed portion 4, the insertion side first engagement portion 11 is pressed against the fixed side first engagement portion 41 by the elasticity of the deformation portion 10, and the insertion side second engagement portion 12 is fixed to the fixed side. It is pressed against the second engaging portion 42. Therefore, the insertion member 1 is fixed to the fixing portion 4.

実施例3の取付構造体は、実施例1の取付構造体と同様に、固定部4のアンダーカット形状が不要になることから、スライドコアのない成形型で支持部材2を成形できる。すなわち、実施例3の取付構造体もまた、安価に製造でき、かつ、形状の自由度と意匠性とに優れる。   Since the attachment structure of the third embodiment does not require the undercut shape of the fixing portion 4 in the same manner as the attachment structure of the first embodiment, the support member 2 can be formed using a mold without a slide core. That is, the mounting structure of Example 3 can also be manufactured at low cost, and is excellent in shape flexibility and design.

実施例1〜3の取付構造体における固定部4または外枠部45は筒状をなすが、本発明の取付構造体における固定部4または外枠部45の形状は筒状に限定されない。例えば固定部4または外枠部45を、径方向断面がコ字状やC字状や二字状となる立壁状にしても良い。   Although the fixing part 4 or the outer frame part 45 in the mounting structures of Examples 1 to 3 has a cylindrical shape, the shape of the fixing part 4 or the outer frame part 45 in the mounting structure of the present invention is not limited to a cylindrical shape. For example, the fixed portion 4 or the outer frame portion 45 may be formed in a standing wall shape whose radial cross section is a U shape, a C shape, or a two shape.

実施例1〜3の取付構造体における挿入部材1はピン係合部13を持つが、本発明の取付構造体の用途によってはピン係合部13を設けなくても良い。   Although the insertion member 1 in the mounting structures of Examples 1 to 3 has the pin engaging portion 13, the pin engaging portion 13 may not be provided depending on the application of the mounting structure of the present invention.

実施例1〜3の取付構造体における挿入部材1は、挿入側第1係合部11と変形部10と挿入側第2係合部12とが同軸的に一体化された形状をなすが、本発明の取付構造体における挿入部材1の形状はこれに限定されない。例えば、挿入側第1係合部11の中心軸と、変形部10の中心軸と、挿入側第2係合部12の中心軸とは、一致していなくても良い。挿入側第1係合部11および挿入側第2係合部12の径方向断面は「ねじれ中心軸Lを中心とする正円」以外であればよい。また、挿入側第1係合部11および挿入側第2係合部12は、径方向断面が高さ方向に一定であるか、または挿入側第1係合部11側から挿入側第2係合部12側に向けて径方向断面が大きくなる形状であればよい。挿入部材1がこれらの形状であれば、固定部4をアンダーカット形状のない形状にできる。   The insertion member 1 in the mounting structures of Examples 1 to 3 has a shape in which the insertion side first engagement portion 11, the deformation portion 10, and the insertion side second engagement portion 12 are integrated coaxially. The shape of the insertion member 1 in the mounting structure of the present invention is not limited to this. For example, the central axis of the insertion-side first engagement portion 11, the central axis of the deformation portion 10, and the central axis of the insertion-side second engagement portion 12 do not have to coincide with each other. The radial cross sections of the insertion side first engagement portion 11 and the insertion side second engagement portion 12 may be other than “a perfect circle centered on the torsion central axis L”. Further, the insertion-side first engagement portion 11 and the insertion-side second engagement portion 12 have a radial cross section that is constant in the height direction, or from the insertion-side first engagement portion 11 side to the insertion-side second engagement. Any shape may be used as long as the radial cross section increases toward the joint portion 12 side. If the insertion member 1 has these shapes, the fixing portion 4 can be formed without an undercut shape.

実施例1〜3の取付構造体において、ねじれ中心軸Lは変形部10の中心軸と一致しているが、挿入側第1係合部11の中心軸と変形部10の中心軸と挿入側第2係合部12の中心軸とが一致していない場合などには、両者は一致しない。しかしこの場合にも、挿入部材1を固定部4に取り付けたときに、固定側第1係合部41が挿入側第1係合部11のねじれ中心軸Lを中心とした回転に干渉し、固定側第2係合部42が挿入側第2係合部12のねじれ中心軸Lを中心とした回転に干渉すれば、実施例1〜3の取付構造体と同様に、挿入部材1の脱離方向の動きを固定部4によって抑制できる。よってこの場合にも、実施例1〜3の取付構造体と同様に、挿入部材1を固定部4に強固に取り付けることができる。   In the mounting structures of the first to third embodiments, the torsional central axis L coincides with the central axis of the deformable portion 10, but the central axis of the insertion side first engaging portion 11, the central axis of the deformable portion 10, and the insertion side In the case where the center axis of the second engagement portion 12 does not match, both do not match. However, also in this case, when the insertion member 1 is attached to the fixed portion 4, the fixed-side first engagement portion 41 interferes with the rotation of the insertion-side first engagement portion 11 around the torsional central axis L, If the fixed-side second engagement portion 42 interferes with the rotation of the insertion-side second engagement portion 12 about the torsional central axis L, the insertion member 1 can be removed as in the mounting structures of the first to third embodiments. The movement in the separating direction can be suppressed by the fixing portion 4. Therefore, also in this case, the insertion member 1 can be firmly attached to the fixing portion 4 as in the attachment structures of the first to third embodiments.

実施例1〜3の取付構造体における挿入部材1は、全体が弾性材料からなるが、本発明の取付構造体における取付部材は、変形部10が弾性材料からなれば良く、挿入側第1係合部11および挿入側第2係合部11は弾性材料以外の材料で形成しても良い。例えば、挿入側第1係合部11および挿入側第2係合部12を樹脂材料で形成して、変形部10と一体化しても良い。   Although the insertion member 1 in the attachment structures of Examples 1 to 3 is entirely made of an elastic material, the attachment member in the attachment structure of the present invention only needs to have the deformable portion 10 made of an elastic material. The joint portion 11 and the insertion-side second engagement portion 11 may be formed of a material other than an elastic material. For example, the insertion side first engagement portion 11 and the insertion side second engagement portion 12 may be formed of a resin material and integrated with the deformation portion 10.
