Description

本発明は、樹脂成形品を相手部材にボルトで取り付ける場合の取付構造、特に樹脂成形品の貫通孔に補強用カラーを配設して、この補強用カラーのボルト挿通孔にボルトを挿通して樹脂成形品を相手部材に締結する取付構造に関する。   The present invention provides a mounting structure in which a resin molded product is attached to a mating member with a bolt, in particular, a reinforcing collar is disposed in a through hole of the resin molded product, and the bolt is inserted into the bolt insertion hole of the reinforcing collar. The present invention relates to a mounting structure for fastening a resin molded product to a mating member.

樹脂成形品が、金属部材等の相手部材に取り付けられる場合に、樹脂成形品の取付部の貫通孔に補強用カラーを嵌め込んで、補強用カラーのボルト挿通孔にボルトを挿入し、そのボルトを相手部材に螺合して樹脂成形品を相手部材に締結することがよく行われている。また、樹脂成形品の取付部と補強用カラーとの高さを同じものとし、樹脂成形品の一部を突出させる構成にして、ボルト等によって樹脂成形品の取付部と相手部材とが締結された際に、樹脂成形品の突出部が圧縮されることによって、ボルトと補強用カラーとの間だけでなく、ボルトと取付部との間にも押圧力が働くようにして、取付部を確実に相手部材に固定するようにしたものが知られている(特許文献1参照)。   When the resin molded product is attached to a mating member such as a metal member, the reinforcing collar is fitted into the through hole of the mounting portion of the resin molded product, and the bolt is inserted into the bolt insertion hole of the reinforcing collar. It is often performed that the resin molded product is fastened to the mating member by screwing the mating member to the mating member. Also, the height of the mounting part of the resin molded product and the height of the reinforcing collar are the same, and a part of the resin molded product is projected, and the mounting part of the resin molded product and the mating member are fastened by bolts or the like. In this case, the protruding part of the resin molded product is compressed, so that not only between the bolt and the reinforcing collar, but also between the bolt and the mounting part, the mounting part is secured. A device that is fixed to a mating member is known (see Patent Document 1).

実願昭55−150964号(実開昭57−76406号)のマイクロフィルム(第3頁14〜19行目、第4図)A microfilm of the actual application No. 55-150964 (No. 57-76406) (page 3, lines 14-19, FIG. 4)

しかし、特許文献1のものでは、取付部の貫通孔に補強用カラーを圧入する際に、取付部と補強用カラーとを同じ高さ位置になるように、補強用カラーを組み付ける必要があり、樹脂成形品の高さに対する補強用カラーの高さを高精度に設定する必要がある。樹脂成形品の樹脂成形における精度向上が困難であるために、補強用カラーの切削加工等の微妙な機械加工の精度を向上する必要が生じる等、補強用カラーの生産効率が低下し、コストアップにつながる。また、実用的には不良品も出やすく信頼性の低い取り付けとなっていた。   However, in the case of Patent Document 1, when the reinforcing collar is press-fitted into the through hole of the attaching portion, it is necessary to assemble the reinforcing collar so that the attaching portion and the reinforcing collar are at the same height position. It is necessary to set the height of the reinforcing collar with respect to the height of the resin molded product with high accuracy. Since it is difficult to improve the accuracy of resin molding of resin molded products, it is necessary to improve the precision of subtle machining such as cutting of the reinforcing collar, resulting in lower production efficiency of the reinforcing collar and higher costs. Leads to. Moreover, in practical use, defective products are easily produced, and the mounting is low in reliability.

例えば、寸法管理の精度が悪くて、取付部の相手部材側や非相手部材側に対して、補強用カラーの相手部材側(以降、先端部側と称す)や非相手部材側(以降、先端部側と称す)が飛び出ている場合には、ボルト等の締め付けによって補強用カラーは押圧されるが、取付部は押圧されないこととなり、確実な固定とはならない。また、取付部が所定の許容寸法より長く、補強用カラーが短くて引っ込んでいる場合は、ボルト等の締め付けによって取付部は押圧されるが、カラーは押圧されない状態となり、確実な固定とはならない。それと共に、取付部の一部が、補強用カラーと相手部材の接触面、或いはボルトとの間に食い込むことがあり、取付部が損傷する結果となる。   For example, the accuracy of dimensional management is poor, and the mating member side of the reinforcing collar (hereinafter referred to as the tip portion side) or the non-partner member side (hereinafter referred to as the tip) with respect to the mating member side or non-partner member side of the mounting portion In the case of protruding part), the reinforcing collar is pressed by tightening a bolt or the like, but the mounting portion is not pressed and is not fixed securely. In addition, when the mounting part is longer than a predetermined allowable dimension and the reinforcing collar is short and retracted, the mounting part is pressed by tightening bolts, etc., but the collar is not pressed and is not securely fixed. . At the same time, a part of the attachment portion may bite between the reinforcing collar and the contact surface of the mating member or the bolt, resulting in damage to the attachment portion.

本発明は、上記のような問題点に鑑みてなされたものであって、その目的は、補強用カラーの先端部及び後端部の両方の寸法管理を容易にすると共に信頼性の高い取り付けが可能な取付部を有する樹脂成形品の取付構造を提供することにある。   The present invention has been made in view of the above problems, and its purpose is to facilitate the dimensional control of both the front end portion and the rear end portion of the reinforcing collar and to provide a highly reliable attachment.

請求項6の発明は、請求項1ないし5のいずれか1つに記載の樹脂成形品の取付構造において、前記補強用カラーは、前記樹脂成形品より圧縮強度が高い材質であることを特徴とする。   The invention of claim 6 is the resin molded article mounting structure according to any one of claims 1 to 5, wherein the reinforcing collar is made of a material having a higher compressive strength than the resin molded article. To do.

請求項1に記載の発明によれば、取付部に対して、補強用カラーの先端部が露出し、且つ後端部が突出しているので、ボルトによって取付部が相手部材に取り付けられた際に、ボルトのフランジ部は、まず突出部に接触して、更にボルトを押し込むと取付部の非相手部材側(ボルト挿入側)に当接して、取付部と補強用カラーの両方を押し込むこととなる。その上で、補強用カラーの先端部が相手部材の接触面に接触して、押し込まれる。従って、締付トルクダウンを低減できて、ガタ付きを防止することができる。また、補強用カラーの先端部の露出量及び後端部の突出量は、上記の組み付け状態を得られるものであれば良いので、寸法に有る程度の幅を持たせることが可能で有り、特許文献1に比較して、寸法管理が容易である。   According to the first aspect of the present invention, the front end portion of the reinforcing collar is exposed and the rear end portion protrudes with respect to the attachment portion, and therefore, when the attachment portion is attached to the mating member by the bolt. The flange portion of the bolt first comes into contact with the protruding portion, and when the bolt is further pushed in, it comes into contact with the non-partner member side (bolt insertion side) of the mounting portion and pushes both the mounting portion and the reinforcing collar. . Then, the tip of the reinforcing collar comes into contact with the contact surface of the mating member and is pushed in. Therefore, it is possible to reduce the tightening torque down and prevent rattling. Further, the exposure amount of the front end portion and the protrusion amount of the rear end portion of the reinforcing collar may be any as long as the above-described assembled state can be obtained. Compared to Document 1, dimensional management is easier.

請求項2に記載の発明によれば、組み付け時における前記補強用カラーの高さH2と、前記凹部の高さH3と、該凹部周りの前記取付部の高さH1とが、H1−H3<H2≦H1の関係にあるので、補強用カラーに所定の締付トルクを掛けることによって、ボルトのフランジ部が、補強用カラーの突出部と取付部の非相手部材側(ボルト挿入側)に当接して、取付部と補強用カラーの両方が押し込まれ、その上で、補強用カラーの先端部が相手部材の接触面に接触して押し込まれるので、緩みにくく、確実な取り付けを得られる。   According to the second aspect of the present invention, the height H2 of the reinforcing collar, the height H3 of the concave portion, and the height H1 of the mounting portion around the concave portion at the time of assembly are H1−H3 < Since the relationship of H2 ≦ H1 is established, by applying a predetermined tightening torque to the reinforcing collar, the flange portion of the bolt contacts the non-mating member side (bolt insertion side) of the protruding portion of the reinforcing collar and the mounting portion. In contact with each other, both the attachment portion and the reinforcing collar are pushed in, and further, the tip end portion of the reinforcing collar is pushed into contact with the contact surface of the mating member, so that it is difficult to loosen and reliable attachment can be obtained.

請求項3に記載の発明によれば、補強用カラーの後端部の突出量T1と、補強用カラーの先端部及び相手部材の接触面の間隔SとがT1≦Sの関係にあるので、前記補強用カラーに所定の締付トルクを掛けることによって、ボルトのフランジ部が、補強用カラーの突出部と取付部の非相手部材側に当接して押し込まれ、その上で、補強用カラーの先端部が相手部材の接触面に接触して押し込まれる。その後、補強用カラーが座屈すると共に該取付部の該フランジ部に接触する部分が圧縮されて、補強用カラーが相手部材に螺合されて締結されることなり、樹脂成形品の取付部と補強用カラーとで確実に締め付けトルクを負担するので、取付部が損傷しにくく且つ緩みにくい、確実な取り付けを得られる。   According to the invention described in claim 3, since the protrusion amount T1 of the rear end portion of the reinforcing collar and the interval S between the front end portion of the reinforcing collar and the contact surface of the mating member are in a relationship of T1 ≦ S, By applying a predetermined tightening torque to the reinforcing collar, the flange portion of the bolt is pushed in contact with the protruding portion of the reinforcing collar and the non-mating member side of the mounting portion, and then the reinforcing collar The tip is pushed in contact with the contact surface of the mating member. After that, the reinforcing collar buckles and the portion of the mounting portion that contacts the flange portion is compressed, and the reinforcing collar is screwed to the mating member and fastened to reinforce the mounting portion of the resin molded product. Since the tightening torque is securely borne by the collar, the mounting portion is hard to be damaged and loosened, so that a reliable mounting can be obtained.

また、補強用カラーが座屈する際に、取付部の相手部材側(非ボルト挿入側)が補強用カラーの先端部より引っ込んでいるので、相手部材の接触面と補強用カラーの先端部との間に取付部の樹脂が挾まれることを確実に防止できる。   Further, when the reinforcing collar is buckled, the mating member side (non-bolt insertion side) of the mounting portion is retracted from the leading end of the reinforcing collar, so that the contact surface of the mating member and the leading end of the reinforcing collar It is possible to reliably prevent the resin of the mounting portion from being sandwiched therebetween.

請求項4の発明によれば、ボルトのフランジ部の直径L1と、凹部の直径L4とが、L1≦L4の関係にあるので、ボルトのフランジ部で、取付部の非相手部材側が圧縮された場合でも、該凹部が、その圧縮の逃げ代となりうるので、無理なく取付部の非相手部材側が圧縮される。   According to the invention of claim 4, since the diameter L1 of the flange portion of the bolt and the diameter L4 of the recess have a relationship of L1 ≦ L4, the non-partner member side of the mounting portion is compressed by the flange portion of the bolt. Even in this case, the concave portion can be a clearance for the compression, so that the non-partner member side of the mounting portion is compressed without difficulty.

請求項5の発明によれば、取付部の非相手部材側が前記ボルトのフランジ部で押し込まれる容積Y1と凹部の空洞容積Y4とが、Y1≦Y4の関係にあるので、ボルトのフランジ部で、取付部の非相手部材側が圧縮された場合でも、該凹部が、その圧縮の逃げ代となりうるので、無理なく取付部の非相手部材側が圧縮される。   According to the invention of claim 5, since the volume Y1 into which the non-mating member side of the mounting portion is pushed by the flange portion of the bolt and the cavity volume Y4 of the recess have a relationship of Y1 ≦ Y4, Even when the non-mating member side of the mounting portion is compressed, the concave portion can be a clearance for the compression, so the non-mating member side of the mounting portion is compressed without difficulty.

請求項6の発明によると、補強用カラーは、樹脂成形品より圧縮強度が高い材質であり、樹脂成形品と補強用カラーとで樹脂成形品と相手部材とを緩むことなく且つ樹脂成形品を損傷すること無く、確実に締結できる。   According to the invention of claim 6, the reinforcing collar is a material having a higher compressive strength than the resin molded product, and the resin molded product and the reinforcing collar can be used without loosening the resin molded product and the mating member. It can be securely fastened without damage.

A protruding portion 71 is provided by the protruding rear end portion 7b. Further, on the mating member side 3a of the mounting portion 3, the tip end portion 7a of the reinforcing collar 7 is exposed from the bottom surface 11a of the recess 11 to the contact surface 9a side of the mating member 9, and the exposed tip portion 7a provides an exposed portion 73. The exposed portion 73 of the distal end portion 7a is assembled to the contact surface 9a of the counterpart member 9 so as to be in a non-contact state.

そして、組み付け後に樹脂成形品1が相手部材9にボルト締結されたときには、補強用カラー7の先端部7aが相手部材9の接触面9aと接触し、且つ補強用カラー7の後端部7bが取付部3の非相手部材側3bと同じ平面になる。   Then, when the resin molded product 1 is bolted to the mating member 9 after assembly, the front end portion 7a of the reinforcing collar 7 is in contact with the contact surface 9a of the mating member 9, and the rear end portion 7b of the reinforcing collar 7 is It becomes the same plane as the non-partner member side 3b of the attachment portion 3.

図2に示すように、補強用カラー7の組み付け時には、前記補強用カラー7の高さH2と、前記凹部11の高さH3と、該凹部11周りの前記取付部3の高さH1とが、H1−H3<H2≦H1の関係にあることが好ましい。H1−H3とは、取付部3の非相手部材側3bと凹部11の底面11aとの厚さである。   As shown in FIG. 2, when the reinforcing collar 7 is assembled, a height H2 of the reinforcing collar 7, a height H3 of the concave portion 11, and a height H1 of the mounting portion 3 around the concave portion 11 are obtained. , H1-H3 <H2 ≦ H1. H1-H3 is the thickness of the non-partner member side 3b of the attachment portion 3 and the bottom surface 11a of the recess 11.

この関係にあることにより、補強用カラー7に所定の締付トルクを掛けることによって、ボルト21のフランジ部23が、補強用カラー7の突出部71と取付部3の非相手部材側3b(ボルト挿入側)に当接して、取付部3と補強用カラー7の両方が押し込まれ、その上で、補強用カラー7の先端部7aが相手部材9の接触面9aに接触して押し込まれるので、ボルト21のフランジ部23を、取付部3の非相手部材側3b及び補強用カラー7の後端部7bに確実に密着させることができ、ボルト21と取付部3とが互いに押圧力を及ぼしあう取付けとすることができるため、振動等の影響を受けにくく緩みにくい取り付けとなる。   Due to this relationship, by applying a predetermined tightening torque to the reinforcing collar 7, the flange portion 23 of the bolt 21 is connected to the protruding portion 71 of the reinforcing collar 7 and the non-partner member side 3 b (bolt). Since both the attachment portion 3 and the reinforcing collar 7 are pushed in, and the tip portion 7a of the reinforcing collar 7 is pushed into contact with the contact surface 9a of the mating member 9, The flange portion 23 of the bolt 21 can be securely brought into close contact with the non-mating member side 3b of the attachment portion 3 and the rear end portion 7b of the reinforcing collar 7, and the bolt 21 and the attachment portion 3 exert a pressing force on each other. Since it can be set as an attachment, the attachment is not easily affected by vibration or the like and is not loosened.

また、組み付け時には、補強用カラー7の先端部7aと相手部材9の接触面9aとの間隔Sと、補強用カラー7の後端部7bの突出量T1とが、T1≦Sの関係にあることが好ましい。   At the time of assembly, the distance S between the front end portion 7a of the reinforcing collar 7 and the contact surface 9a of the mating member 9 and the protruding amount T1 of the rear end portion 7b of the reinforcing collar 7 have a relationship of T1 ≦ S. It is preferable.

この関係にあることによって、補強用カラー7に所定の締付トルクを掛けて、ボルト21のフランジ部23が補強用カラー7の突出部71と取付部3の非相手部材側3b(ボルト挿入側)に当接して押し込まれ、その上で、補強用カラー7の先端部7aが相手部材9の接触面9aに接触して押し込まれる。その後、補強用カラー7が座屈すると共に該取付部3の該フランジ部23に接触する部分が圧縮されて、補強用カラー7が相手部材9に螺合されて締結されることとなる。従って、樹脂成形品1の取付部3と補強用カラー7とで確実に締め付けトルクを負担するので、取付部3が損傷しにくく且つ緩みにくい、確実な取り付けを得られる。また、補強用カラー7が座屈する際に、取付部3の相手部材側3a(非ボルト挿入側)に凹部11の底面11aが補強用カラー7の先端部7aより引っ込んでいるので、相手部材9の接触面9aと補強用カラー7の先端部7aとの間に取付部3の樹脂が挾まれることを確実に防止できる。   Due to this relationship, a predetermined tightening torque is applied to the reinforcing collar 7 so that the flange portion 23 of the bolt 21 is connected to the protruding portion 71 of the reinforcing collar 7 and the non-partner member side 3b of the mounting portion 3 (bolt insertion side). The tip 7a of the reinforcing collar 7 is pushed in contact with the contact surface 9a of the mating member 9. Thereafter, the reinforcing collar 7 is buckled and the portion of the mounting portion 3 that contacts the flange portion 23 is compressed, and the reinforcing collar 7 is screwed into the mating member 9 and fastened. Therefore, since the tightening torque is reliably borne by the mounting portion 3 of the resin molded product 1 and the reinforcing collar 7, it is possible to obtain a reliable mounting in which the mounting portion 3 is not easily damaged and loosened. Further, when the reinforcing collar 7 is buckled, the bottom surface 11a of the recess 11 is retracted from the distal end portion 7a of the reinforcing collar 7 to the mating member side 3a (non-bolt insertion side) of the mounting portion 3. It is possible to reliably prevent the resin of the mounting portion 3 from being sandwiched between the contact surface 9a and the distal end portion 7a of the reinforcing collar 7.

ボルト21のフランジ部23の直径L1と凹部11の直径L4とは、L1≦L4の関係にあることが好ましい。このことで、ボルト21のフランジ部23で、取付部3の非相手部材側3b(ボルト挿入側)が押圧された場合でも、凹部11が、その押圧力の過大な負荷を軽減するので、無理なく取付部3の非相手部材側3b(ボルト挿入側)が押圧、圧縮される。   The diameter L1 of the flange portion 23 of the bolt 21 and the diameter L4 of the recess 11 are preferably in a relationship of L1 ≦ L4. In this way, even when the non-mating member side 3b (bolt insertion side) of the mounting portion 3 is pressed by the flange portion 23 of the bolt 21, the concave portion 11 reduces the excessive load of the pressing force. The non-mating member side 3b (bolt insertion side) of the mounting portion 3 is pressed and compressed.

取付部3の非相手部材側3bがボルト21のフランジ部23で押し込まれる容積をY1、凹部11の容積をY2、補強用カラー7の露出部73の容積をY3、凹部11の空洞容積をY4とした時に、Y1≦Y4であって、Y4=Y2−Y3の関係にあることが好ましい。この関係にあることによって、ボルト21のフランジ部23で、取付部3の非相手部材側3b(ボルト挿入側)が圧縮された場合でも、該凹部11がその圧縮の逃げ代となりうるので、無理なく取付部3の非相手部材側3b(ボルト挿入側)が圧縮される。   The volume by which the non-mating member side 3b of the mounting portion 3 is pushed in by the flange portion 23 of the bolt 21 is Y1, the volume of the recessed portion 11 is Y2, the volume of the exposed portion 73 of the reinforcing collar 7 is Y3, and the cavity volume of the recessed portion 11 is Y4. It is preferable that Y1 ≦ Y4 and Y4 = Y2−Y3. Because of this relationship, even when the non-mating member side 3b (bolt insertion side) of the mounting portion 3 is compressed by the flange portion 23 of the bolt 21, the concave portion 11 can be a clearance for the compression. The non-mating member side 3b (bolt insertion side) of the mounting portion 3 is compressed.

次に、図2、3に基づいて組み付け状態を説明する。尚、ボルト21のネジ部21aは省略して、フランジ部23のみ示す。   Next, the assembled state will be described with reference to FIGS. Note that the screw portion 21a of the bolt 21 is omitted, and only the flange portion 23 is shown.

まず、長さH1の取付部3の相手部材側3aに、深さH3、直径L4の凹部11を備えた樹脂成形品1と、長さH2、外径L2、内径L3の補強用カラー7とを用意する。そして、補強用カラー7を樹脂成形品1の取付部3の貫通孔5に凹部11のない非相手部材側3bから圧入して、嵌合する。この時に、補強用カラー7は取付部3に対して、相手部材側3aで露出部73の高さT2、非相手部材側3bで突出部71の高さT1となり、間隔Sが確保された状態にする。これによって、どちらの方向にも補強用カラー7が少し飛び出たようにすれば良いので、寸法管理が上記特許文献1に比較して容易である。   First, a resin molded product 1 provided with a recess 11 having a depth H3 and a diameter L4 on the counterpart member side 3a of the attachment portion 3 having a length H1, and a reinforcing collar 7 having a length H2, an outer diameter L2, and an inner diameter L3, Prepare. Then, the reinforcing collar 7 is press-fitted into the through-hole 5 of the mounting portion 3 of the resin molded product 1 from the non-partner member side 3b without the recess 11 and is fitted. At this time, the reinforcing collar 7 has a height T2 of the exposed portion 73 on the counterpart member side 3a and a height T1 of the protruding portion 71 on the non-mate member side 3b with respect to the attachment portion 3, and the interval S is secured. To. As a result, it is sufficient that the reinforcing collar 7 protrudes slightly in either direction. Therefore, dimensional management is easier than in the above-mentioned Patent Document 1.

それから、ボルト21を補強用カラー7のボルト挿通孔7cに挿入して、ボルト21のネジ部21aを相手部材9のメネジ9bに螺合させていく。これにより、図3(a)に示すように、ボルト21のフランジ部23が、補強用カラー7の後端部7bに接触する。この状態では、補強用カラー7の突出部71と露出部73が、それぞれ取付部3の非相手部材側3b(ボルト挿入側)と相手部材側3a(非ボルト挿入側)に凹部11の底面11aから出た状態で有り、補強用カラー7の先端部7aと相手部材9の接触面9aとの間隔Sが維持されている。   Then, the bolt 21 is inserted into the bolt insertion hole 7 c of the reinforcing collar 7, and the screw portion 21 a of the bolt 21 is screwed into the female screw 9 b of the mating member 9. As a result, as shown in FIG. 3A, the flange portion 23 of the bolt 21 contacts the rear end portion 7 b of the reinforcing collar 7. In this state, the protruding portion 71 and the exposed portion 73 of the reinforcing collar 7 are respectively connected to the bottom surface 11a of the recess 11 on the non-mate member side 3b (bolt insertion side) and the counterpart member side 3a (non-bolt insertion side) of the attachment portion 3, respectively. The distance S between the tip 7a of the reinforcing collar 7 and the contact surface 9a of the mating member 9 is maintained.

更に螺合状態を進めると、図3(b)に示すように、補強用カラー7の後端部7bが取付部3に対して相対的に押し込まれて、取付部3の非相手部材側3b(ボルト挿入側)と補強用カラー7の後端部7bとが同じ平面に一致する。なお、取付部3において、補強用カラー7に密着した部分は、補強用カラー7の螺合方向への進行により、一緒に移動する部分もある。そして、取付部3の非相手部材側3b(ボルト挿入側)と補強用カラー7の後端部7bとが同じ平面に一致した場合に、補強用カラー7の先端部7aは、まだ相手部材9の接触面9aに接触せず、間隔S1(S1<S)が設けられた状態になっている。   When the screwing state is further advanced, as shown in FIG. 3 (b), the rear end portion 7b of the reinforcing collar 7 is pushed relative to the mounting portion 3, and the non-partner side 3b of the mounting portion 3 is pressed. (Bolt insertion side) and the rear end portion 7b of the reinforcing collar 7 coincide with the same plane. Note that the portion of the mounting portion 3 that is in close contact with the reinforcing collar 7 also moves together as the reinforcing collar 7 advances in the screwing direction. When the non-mating member side 3b (bolt insertion side) of the mounting portion 3 and the rear end portion 7b of the reinforcing collar 7 coincide with the same plane, the leading end portion 7a of the reinforcing collar 7 is still on the mating member 9. The contact surface 9a is not contacted, and the interval S1 (S1 <S) is provided.

そして、更に締め付けトルクを掛けて、ボルト21を進入方向に押し込むと、図3(c)に示すように、取付部3の非相手部材側3b(ボルト挿入側)と補強用カラー7の後端部7bとが、ボルト21のフランジ部23に押されて一緒に挿入方向に進む。この時、補強用カラー7はまだ座屈せず、補強用カラー7の先端部7aが接触面9aに接触するまで進入方向に進行し、この場合に取付部3の非相手部材側3bは少し圧縮されている。この時の圧縮代S2が、間隔S1とほぼ同じとなる。   Then, when further tightening torque is applied and the bolt 21 is pushed in the approaching direction, as shown in FIG. 3C, the non-partner member side 3b (bolt insertion side) of the mounting portion 3 and the rear end of the reinforcing collar 7 The portion 7b is pushed by the flange portion 23 of the bolt 21 and advances together in the insertion direction. At this time, the reinforcing collar 7 has not yet buckled, and proceeds in the entering direction until the tip 7a of the reinforcing collar 7 contacts the contact surface 9a. In this case, the non-partner member side 3b of the mounting portion 3 is slightly compressed. Has been. The compression allowance S2 at this time is substantially the same as the interval S1.

図3(b)の状態で、間隔S1=0となり、補強用カラー7の先端部7aが、相手部材9の接触面9aに接触すると共に、取付部3の非相手部材側3b(ボルト挿入側)と補強用カラー7の後端部7bとが同じ平面に一致する場合もある。この場合には、図3(c)の状態はなくて、圧縮代S2=0である。尚、このように、S1=0、S2=0に寸法管理することよりも、S1≒S2>0になるように寸法管理して、場合によっては、S1=0、S2=0となるものも有り得るとする方が管理上で有利である。   In the state of FIG. 3 (b), the interval S1 = 0, the tip 7a of the reinforcing collar 7 contacts the contact surface 9a of the mating member 9, and the non-mating member side 3b (bolt insertion side) of the mounting portion 3 ) And the rear end portion 7b of the reinforcing collar 7 may coincide with the same plane. In this case, there is no state in FIG. 3C, and the compression allowance S2 = 0. In addition, in this way, rather than managing the dimensions to S1 = 0 and S2 = 0, the dimensions are managed so that S1≈S2> 0, and in some cases, S1 = 0 and S2 = 0. It is more advantageous in terms of management.

それから更に、所定の締め付けトルクまで締め付けると、取付部3の非相手部材側3bはさらに圧縮されると共に、補強用カラー7が座屈する。この時、取付部3の圧縮代S3が、S3>S2の関係になっており、補強用カラー7が座屈すると共に取付部3の非相手部材側3bが圧縮されているので、樹脂成形品1の取付部3と補強用カラー7とで、ボルト21のフランジ23による締め付けを負担することができる。   When further tightened to a predetermined tightening torque, the non-partner member side 3b of the mounting portion 3 is further compressed and the reinforcing collar 7 is buckled. At this time, the compression allowance S3 of the attachment portion 3 has a relationship of S3> S2, the reinforcing collar 7 is buckled, and the non-mating member side 3b of the attachment portion 3 is compressed. The mounting portion 3 and the reinforcing collar 7 can bear the tightening of the bolt 21 by the flange 23.

なお、この時、凹部11は、取付部3の圧縮により少し狭くなっているものと推測されるが、形状的には一定でないので、図3(d)では模式的に示した。特に、樹脂成形品1の材質や凹部11の大きさ、締め付けトルクなどによって、この狭くなる状況は異なり、場合によっては狭くならない場合もあり得るので、本発明では、最大狭くなっても良いようなスペースを設けるようにした。   In addition, at this time, although it is estimated that the recessed part 11 has become a little narrow by compression of the attachment part 3, since it is not constant in shape, it showed typically in FIG.3 (d). In particular, this narrowing situation varies depending on the material of the resin molded product 1, the size of the recess 11, the tightening torque, and the like, and in some cases it may not be narrowed. A space was provided.

この状態で締め付けが完了するので、樹脂成形品1が緩むことなく確実に相手部材9に締結される。それと共に、樹脂成形品1の取付部3と補強用カラー7の少なくとも一方の面が同じ平面になるような寸法精度、取付精度を必要としないので、寸法管理及び組付け精度の管理が比較的容易である。   Since the tightening is completed in this state, the resin molded product 1 is securely fastened to the mating member 9 without loosening. At the same time, since the dimensional accuracy and mounting accuracy are not required so that at least one surface of the mounting portion 3 of the resin molded product 1 and the reinforcing collar 7 are the same plane, the management of the dimensional control and the assembly accuracy is relatively low. Easy.

(その他の実施形態)
凹部11は、底面と深さを有する円筒状の断面になっているが、他の形状でも良く、例えば、相手面側から非相手面側に向かって徐々に径が狭くなる傾斜面とし、断面としてみれば台形或いは三角形の凹部としても良い。
(Other embodiments)
The concave portion 11 has a cylindrical cross section having a bottom surface and a depth, but may have other shapes, for example, an inclined surface whose diameter gradually decreases from the mating surface side toward the non-mating surface side, If it sees, it is good also as a trapezoid or a triangular recessed part.

本発明は、樹脂成形品を樹脂成形品よりも高強度の相手部材に締結するものあれば適用可能なものであり、自動車用部品では、オイルパン、ヘッドカバー、オイルストレーナ、タイミングベルトカバー等が挙げられる。   The present invention is applicable as long as the resin molded product is fastened to a mating member having a higher strength than the resin molded product. For automotive parts, an oil pan, a head cover, an oil strainer, a timing belt cover, and the like can be cited. It is done.
