本発明は、固定構造に関する。詳細には、取付部材に被取付部材を固定するためのカラーを有する固定構造に関する。   The present invention relates to a fixing structure. Specifically, the present invention relates to a fixing structure having a collar for fixing a member to be attached to the attachment member.

従来、固定構造としては、ボルトが固定された取付部材と、ボルトが挿通される孔部が設けられ取付部材に取り付けられる被取付部材としてのプロテクタと、孔部に挿通されて固定されボルトに締結されるナットを介してプロテクタを取付部材に固定する環状のカラーとを備えたものが知られている（例えば、特許文献１参照）。   Conventionally, as a fixing structure, a mounting member to which a bolt is fixed, a protector as a mounted member that is provided with a hole portion through which the bolt is inserted and is attached to the mounting member, and is fixed by being inserted into the hole portion and fastened to the bolt There is known one provided with an annular collar that fixes a protector to a mounting member via a nut that is provided (see, for example, Patent Document 1).

ところで、上記特許文献１のような固定構造では、取付部材のボルトをカラーに挿通させる際に、ボルトとカラーとが干渉してボルトが損傷してしまうことを防止するために、カラーの内径が大きく設定されている。   By the way, in the fixing structure like the above-mentioned patent document 1, when the bolt of the mounting member is inserted through the collar, the inner diameter of the collar is set to prevent the bolt and the collar from interfering with each other and damaging the bolt. It is set large.

このため、ボルトにナットを締結する前の状態では、ボルトの外周面とカラーの内周面との距離が長く、取付部材に対する被取付部材のガタが大きくなっていた。   For this reason, in the state before fastening the nut to the bolt, the distance between the outer peripheral surface of the bolt and the inner peripheral surface of the collar is long, and the backlash of the mounted member with respect to the mounting member is large.

また、ボルトをカラーに挿通した状態では、取付部材に対して被取付部材が移動するので、この被取付部材の移動によって被取付部材が周辺部材と干渉してしまう恐れがある。   In addition, in a state where the bolt is inserted through the collar, the attached member moves with respect to the attaching member. Therefore, the attached member may interfere with the peripheral members due to the movement of the attached member.

この被取付部材と周辺部材との干渉を防止するために、被取付部材と周辺部材との間の距離を、ボルトの外周面とカラーの内周面との間の距離より長くなるように設定し、被取付部材にガタが生じても、被取付部材が周辺部材と干渉しないようにされている。   In order to prevent interference between the mounted member and the peripheral member, the distance between the mounted member and the peripheral member is set to be longer than the distance between the outer peripheral surface of the bolt and the inner peripheral surface of the collar. And even if a backlash arises in a to-be-attached member, a to-be-attached member is made not to interfere with a peripheral member.

このため、ボルトの外周面とカラーの内周面との距離が長ければ長いほど、被取付部材と周辺部材との間の距離も長くする必要があり、周辺部材の配置スペースが大型化するなど、周辺部材の配置レイアウトに影響を与えていた。   For this reason, the longer the distance between the outer peripheral surface of the bolt and the inner peripheral surface of the collar, the longer the distance between the attached member and the peripheral member, and the larger the arrangement space of the peripheral member. This has affected the layout of peripheral members.

そこで、この発明は、取付部材に対する被取付部材のガタを小さくすることができ、周辺部材の配置レイアウトへの影響を抑制することができる固定構造の提供を目的としている。   Therefore, an object of the present invention is to provide a fixing structure that can reduce the backlash of the mounted member relative to the mounting member and can suppress the influence on the arrangement layout of the peripheral members.

請求項１記載の発明は、ボルトが固定された取付部材と、前記ボルトが挿通される孔部が設けられ前記取付部材に取り付けられる被取付部材と、前記孔部に挿通されて固定され前記ボルトに締結されるナットを介して前記被取付部材を前記取付部材に固定する環状のカラーと、前記カラーの内周面に設けられ前記カラーの内周面から内方に向けて突出し周方向に複数配置されたリブとを有することを特徴とする固定構造である。   According to the first aspect of the present invention, the mounting member to which the bolt is fixed, the hole to which the bolt is inserted is provided, the mounted member to be attached to the mounting member, and the bolt to be fixed by being inserted into the hole. An annular collar for fixing the attached member to the attachment member via a nut fastened to the collar, and a plurality of protrusions in the circumferential direction that are provided on the inner peripheral surface of the collar and project inward from the inner peripheral surface of the collar It is a fixed structure characterized by having a rib arranged.

この固定構造では、カラーの内周面に、カラーの内周面から内方に向けて突出し周方向に複数配置されたリブが設けられているので、カラーにボルトが挿通された状態で、ボルトと複数のリブとの間の距離を短くすることができ、取付部材に対する被取付部材のガタを小さくすることができる。   In this fixed structure, the inner peripheral surface of the collar is provided with a plurality of ribs that protrude inward from the inner peripheral surface of the collar and are arranged in the circumferential direction. And the plurality of ribs can be shortened, and the backlash of the mounted member relative to the mounting member can be reduced.

また、ボルトと複数のリブとの間の距離を短くすることができるので、被取付部材と周辺部材との間の距離も短くすることができ、周辺部材の配置レイアウトの自由度を向上することができる。   In addition, since the distance between the bolt and the plurality of ribs can be shortened, the distance between the attached member and the peripheral member can also be shortened, and the degree of freedom in the layout of the peripheral member is improved. Can do.

従って、このような固定構造では、取付部材に対する被取付部材のガタを小さくすることができ、周辺部材の配置レイアウトへの影響を抑制することができる。   Therefore, in such a fixing structure, the backlash of the mounted member relative to the mounting member can be reduced, and the influence on the arrangement layout of the peripheral members can be suppressed.

請求項２記載の発明は、請求項１記載の固定構造であって、複数の前記リブは、前記カラーの内周面の周方向等間隔に少なくとも３つ配置されていることを特徴とする。   A second aspect of the present invention is the fixing structure according to the first aspect, wherein the plurality of ribs are arranged at equal intervals in the circumferential direction of the inner peripheral surface of the collar.

この固定構造では、複数のリブが、カラーの内周面の周方向等間隔に少なくとも３つ配置されているので、最小限のリブの数でボルトに対するカラーの中心出しを可能とし、取付部材に対する被取付部材のガタを小さくできると共に、カラーの形状を簡易化することができる。   In this fixing structure, since the plurality of ribs are arranged at equal intervals in the circumferential direction of the inner peripheral surface of the collar, the collar can be centered with respect to the bolt with the minimum number of ribs, and the mounting member can be centered. The backlash of the attached member can be reduced, and the shape of the collar can be simplified.

請求項３記載の発明は、請求項１又は２記載の固定構造であって、前記リブの前記取付部材側には、前記カラーの外部から内部に向けて前記カラーの径を小さくする方向に傾斜されたテーパが設けられていることを特徴とする。   The invention according to claim 3 is the fixing structure according to claim 1 or 2, wherein the rib is inclined toward the mounting member side in a direction of decreasing the diameter of the collar from the outside to the inside of the collar. A tapered shape is provided.

この固定構造では、リブの取付部材側に、カラーの外部から内部に向けてカラーの径を小さくする方向に傾斜されたテーパが設けられているので、取付部材に対して被取付部材をテーパに沿って斜めに組付けることを許容し、ボルトに対するリブの引っ掛かりを防止することができ、組付性を向上することができる。   In this fixing structure, since the taper which is inclined in the direction of decreasing the diameter of the collar from the outside to the inside of the collar is provided on the mounting member side of the rib, the mounted member is tapered with respect to the mounting member. Assembling at an angle along the line is allowed, and the hook of the rib against the bolt can be prevented, so that the assembling property can be improved.

本発明によれば、取付部材に対する被取付部材のガタを小さくすることができ、周辺部材の配置レイアウトへの影響を抑制することができる固定構造を提供することができるという効果を奏する。   Advantageous Effects of Invention According to the present invention, there is an effect that it is possible to provide a fixing structure that can reduce the backlash of the attached member relative to the attachment member and can suppress the influence on the arrangement layout of the peripheral members.

図１〜図５を用いて本発明の実施の形態に係る固定構造について説明する。   The fixing structure according to the embodiment of the present invention will be described with reference to FIGS.

本実施の形態に係る固定構造１は、ボルト３が固定された取付部材５と、ボルト３が挿通される孔部７が設けられ取付部材５に取り付けられる被取付部材９と、孔部７に挿通されて固定されボルト３に締結されるナット１１を介して被取付部材９を取付部材５に固定する環状のカラー１３とを備えている。   The fixing structure 1 according to the present embodiment includes an attachment member 5 to which the bolt 3 is fixed, a hole 7 into which the bolt 3 is inserted and a member 9 to be attached to the attachment member 5, and the hole 7. An annular collar 13 that fixes the attached member 9 to the attachment member 5 through a nut 11 that is inserted and fixed and fastened to the bolt 3 is provided.

そして、カラー１３の内周面には、カラー１３の内周面から内方に向けて突出し周方向に複数配置されたリブ１５が設けられている。   The inner peripheral surface of the collar 13 is provided with a plurality of ribs 15 protruding inward from the inner peripheral surface of the collar 13 and arranged in the circumferential direction.

また、複数のリブ１５は、カラー１３の内周面の周方向等間隔に少なくとも３つ配置されている。   The plurality of ribs 15 are arranged at equal intervals in the circumferential direction of the inner peripheral surface of the collar 13.

さらに、リブ１５の取付部材５側には、カラー１３の外部から内部に向けてカラー１３の径を小さくする方向に傾斜されたテーパ１７が設けられている。   Further, a taper 17 that is inclined in a direction of decreasing the diameter of the collar 13 from the outside to the inside of the collar 13 is provided on the mounting member 5 side of the rib 15.

図１〜図５に示すように、固定構造１は、車両に配置される金属材料からなるパネルなどの取付部材５に対して、車両に配索される電線の周囲を覆い電線を保護する樹脂材料からなるプロテクタなどの被取付部材９を固定する構造に適用される。   As shown in FIG. 1 to FIG. 5, the fixing structure 1 is a resin that covers the periphery of an electric wire arranged in the vehicle and protects the electric wire with respect to an attachment member 5 such as a panel made of a metal material arranged in the vehicle. The present invention is applied to a structure for fixing a member 9 to be attached such as a protector made of a material.

取付部材５には、ボルト３の頭部が溶接などの接合手段を介して固定され、ボルト３の締結部が外部に向けて突出されている。   The head of the bolt 3 is fixed to the mounting member 5 via a joining means such as welding, and the fastening portion of the bolt 3 protrudes outward.

この取付部材５のボルト３が突出された側には、被取付部材９が配置される。   A mounted member 9 is arranged on the side of the mounting member 5 from which the bolt 3 is projected.

被取付部材９には、ボルト３が挿通される孔部７が被取付部材９を貫通して設けられている。   The attached member 9 is provided with a hole 7 through which the bolt 3 is inserted so as to penetrate the attached member 9.

この孔部７は、ボルト３の締結部の外径より内径が大きく設定され、内周面にカラー１３が圧入して固定されている。   The hole 7 has an inner diameter larger than the outer diameter of the fastening portion of the bolt 3, and a collar 13 is press-fitted and fixed to the inner peripheral surface.

カラー１３は、金属材料からなり、環状に形成され、圧入部１９と、当接部２１と、複数のリブ１５とを備えている。   The collar 13 is made of a metal material, is formed in an annular shape, and includes a press-fit portion 19, a contact portion 21, and a plurality of ribs 15.

圧入部１９は、被取付部材９の孔部７に挿入可能なように円筒状に形成され、被取付部材９の孔部７に圧入され、カラー１３を被取付部材９に固定する。   The press-fit portion 19 is formed in a cylindrical shape so as to be inserted into the hole portion 7 of the attached member 9, and is press-fitted into the hole portion 7 of the attached member 9, thereby fixing the collar 13 to the attached member 9.

当接部２１は、圧入部１９の一端側にフランジ状に形成され、圧入部１９が孔部７に圧入された状態で、孔部７の縁部を覆うように配置される。   The contact portion 21 is formed in a flange shape on one end side of the press-fit portion 19, and is disposed so as to cover the edge portion of the hole portion 7 in a state where the press-fit portion 19 is press-fitted into the hole portion 7.

この当接部２１は、被取付部材９が取付部材５に配置され、カラー１３にボルト３が挿通された状態で、ボルト３の締結部に締結されるナット１１と当接し、被取付部材９を取付部材５との間で挟み込むように、被取付部材９を取付部材５に固定する。   The contact portion 21 contacts the nut 11 fastened to the fastening portion of the bolt 3 in a state where the attached member 9 is disposed on the attachment member 5 and the bolt 3 is inserted through the collar 13. Is attached to the attachment member 5 so that the attachment member 5 is sandwiched between the attachment member 5 and the attachment member 5.

このようにカラー１３を介して被取付部材９を取付部材５に固定することにより、樹脂製の被取付部材９がナット１１と当接して、被取付部材９が損傷することを防止することができる。   By fixing the mounted member 9 to the mounting member 5 through the collar 13 in this way, it is possible to prevent the mounted member 9 made of resin from coming into contact with the nut 11 and damaging the mounted member 9. it can.

ここで、取付部材５には、被取付部材９の他に、ＥＣＵやモータなどの周辺部材２３が配置されている。   Here, in addition to the mounted member 9, a peripheral member 23 such as an ECU or a motor is disposed on the mounting member 5.

この周辺部材２３と被取付部材９との間の距離Ａは、ボルト３の外周面とカラー１３の内周面との間の距離Ｂより長く設定する必要がある。   The distance A between the peripheral member 23 and the attached member 9 needs to be set longer than the distance B between the outer peripheral surface of the bolt 3 and the inner peripheral surface of the collar 13.

これは、ボルト３にナット１１を締結する前であって、ボルト３がカラー１３を挿通した状態で、被取付部材９が外力によって移動されたときに、周辺部材２３と被取付部材９とが干渉することを防止するためである。   This is before the nut 11 is fastened to the bolt 3, and when the attached member 9 is moved by an external force with the bolt 3 inserted through the collar 13, the peripheral member 23 and the attached member 9 are This is to prevent interference.

これに対して、ボルト３の外周面とカラー１３の内周面との間の距離Ｂは、カラー１３をボルト３に挿入するときに、カラー１３がボルト３の締結部と干渉して、ボルト３の損傷を防止するために、ある程度長く設定する必要がある。   On the other hand, the distance B between the outer peripheral surface of the bolt 3 and the inner peripheral surface of the collar 13 is such that when the collar 13 is inserted into the bolt 3, the collar 13 interferes with the fastening portion of the bolt 3. In order to prevent the damage 3, it is necessary to set the length to some extent.

このため、ボルト３の外周面とカラー１３の内周面との間の距離Ｂを長くしてしまうと、周辺部材２３と被取付部材９との間の距離Ａも長くする必要があり、周辺部材２３の配置スペースを大型化したり、配置位置に制約を与えるなど、周辺部材２３の配置レイアウトに大きな影響を与えてしまう。   For this reason, if the distance B between the outer peripheral surface of the bolt 3 and the inner peripheral surface of the collar 13 is increased, the distance A between the peripheral member 23 and the attached member 9 also needs to be increased. The arrangement layout of the peripheral members 23 is greatly affected, for example, the arrangement space of the members 23 is increased, or the arrangement position is restricted.

また、ボルト３の外周面とカラー１３の内周面との間の距離Ｂが長いと、ボルト３にナット１１を締結する前の状態で、取付部材５に対する被取付部材９のガタが大きくなってしまう。   Further, when the distance B between the outer peripheral surface of the bolt 3 and the inner peripheral surface of the collar 13 is long, the backlash of the mounted member 9 with respect to the mounting member 5 becomes large before the nut 11 is fastened to the bolt 3. End up.

そこで、カラー１３の圧入部１９の内周面には、内方に向けて突出し周方向に複数配置されたリブ１５が設けられている。   Therefore, a plurality of ribs 15 projecting inward and arranged in the circumferential direction are provided on the inner peripheral surface of the press-fitting portion 19 of the collar 13.

このようにカラー１３の内周面に複数のリブ１５を設けることにより、ボルト３の外周面とカラー１３の内周面との間の距離Ｂよりボルト３の外周面とリブ１５の先端との距離Ｃを短くすることができる。   By providing the plurality of ribs 15 on the inner peripheral surface of the collar 13 in this manner, the distance between the outer peripheral surface of the bolt 3 and the inner peripheral surface of the collar 13 is less than the distance B between the outer peripheral surface of the bolt 3 and the tip of the rib 15. The distance C can be shortened.

このため、周辺部材２３と被取付部材９との間の距離Ａも短くすることができ、周辺部材２３の配置レイアウトへの影響を抑制し、周辺部材２３の配置スペースを小型化し、周辺部材２３の配置レイアウトの自由度を向上することができる。   For this reason, the distance A between the peripheral member 23 and the attached member 9 can also be shortened, the influence on the arrangement layout of the peripheral member 23 is suppressed, the arrangement space of the peripheral member 23 is reduced, and the peripheral member 23 is reduced. The degree of freedom of the layout can be improved.

加えて、ボルト３にナット１１を締結する前の状態で、取付部材５に対する被取付部材９のガタを小さくすることができる。   In addition, the backlash of the mounted member 9 with respect to the mounting member 5 can be reduced before the nut 11 is fastened to the bolt 3.

このような複数のリブ１５は、カラー１３の内周面の周方向等間隔（ここでは１２０°間隔）に３つ配置されている。   Three such ribs 15 are arranged at equal intervals in the circumferential direction of the inner peripheral surface of the collar 13 (here, 120 ° intervals).

このように複数のリブ１５を配置することにより、最小限のリブ１５の数でボルト３に対するカラー１３の中心出しを可能とし、取付部材５に対する被取付部材９のガタを小さくできる。   By arranging the plurality of ribs 15 in this way, the collar 13 can be centered with respect to the bolt 3 with the minimum number of ribs 15, and the backlash of the mounted member 9 with respect to the mounting member 5 can be reduced.

また、リブ１５の数を最小限とすることにより、カラー１３の形状を簡易化することができ、カラー１３の製造コストを低コスト化することができる。   In addition, by minimizing the number of ribs 15, the shape of the collar 13 can be simplified, and the manufacturing cost of the collar 13 can be reduced.

さらに、リブ１５の数を最小限とすることにより、カラー１３にボルト３を挿入するときに、ボルト３とリブ１５とが干渉する機会を最小限に抑えることができる。   Furthermore, by minimizing the number of ribs 15, when the bolt 3 is inserted into the collar 13, the chance of interference between the bolt 3 and the rib 15 can be minimized.

このような複数のリブ１５の取付部材５側には、カラー１３の外部から内部に向けてカラー１３の径を小さくする方向に傾斜されたテーパ１７が設けられている。   On the mounting member 5 side of the plurality of ribs 15, a taper 17 is provided that is inclined in the direction of decreasing the diameter of the collar 13 from the outside to the inside of the collar 13.

このようにリブ１５にテーパ１７を設けることにより、取付部材５に対して被取付部材９をテーパ１７に沿って斜めに組付けることを許容することができる。   By providing the rib 15 with the taper 17 in this manner, it is possible to allow the attachment member 9 to be assembled obliquely along the taper 17 with respect to the attachment member 5.

また、リブ１５にテーパ１７を設けることにより、ボルト３とリブ１５とが干渉したときに、ボルト３に対するリブ１５の引っ掛かりを防止でき、ボルト３の損傷を抑制することができる。   Further, by providing the rib 15 with the taper 17, when the bolt 3 and the rib 15 interfere with each other, the rib 15 can be prevented from being caught by the bolt 3, and damage to the bolt 3 can be suppressed.

なお、複数のリブ１５には、テーパ１７と反対側に、テーパ１７と対称形状となるように、カラー１３の外部から内部に向けてカラー１３の径を小さくする方向に傾斜された解除テーパ２５が設けられている。   The plurality of ribs 15 are provided on the opposite side of the taper 17 so as to be symmetrical with the taper 17. The release taper 25 is inclined in the direction of decreasing the diameter of the collar 13 from the outside to the inside of the collar 13. Is provided.

この解除テーパ２５は、取付部材５から被取付部材９を取り外すときに、ボルト３に対するリブ１５の引っ掛かりを防止し、ボルト３の損傷を抑制する。   The release taper 25 prevents the rib 15 from being caught by the bolt 3 when the member 9 to be attached is removed from the attachment member 5, and suppresses damage to the bolt 3.

このような固定構造１では、カラー１３の内周面に、カラー１３の内周面から内方に向けて突出し周方向に複数配置されたリブ１５が設けられているので、カラー１３にボルト３が挿通された状態で、ボルト３と複数のリブ１５との間の距離を短くすることができ、取付部材５に対する被取付部材９のガタを小さくすることができる。   In such a fixing structure 1, a plurality of ribs 15 protruding inward from the inner peripheral surface of the collar 13 and arranged in the circumferential direction are provided on the inner peripheral surface of the collar 13. In the state in which is inserted, the distance between the bolt 3 and the plurality of ribs 15 can be shortened, and the backlash of the mounted member 9 with respect to the mounting member 5 can be reduced.

また、ボルト３と複数のリブ１５との間の距離を短くすることができるので、被取付部材９と周辺部材２３との間の距離も短くすることができ、周辺部材２３の配置レイアウトの自由度を向上することができる。   Further, since the distance between the bolt 3 and the plurality of ribs 15 can be shortened, the distance between the attached member 9 and the peripheral member 23 can also be shortened, and the layout of the peripheral member 23 can be freely set. The degree can be improved.

従って、このような固定構造１では、取付部材５に対する被取付部材９のガタを小さくすることができ、周辺部材２３の配置レイアウトへの影響を抑制することができる。   Therefore, in such a fixing structure 1, the backlash of the mounted member 9 with respect to the mounting member 5 can be reduced, and the influence on the layout of the peripheral members 23 can be suppressed.

また、複数のリブ１５は、カラー１３の内周面の周方向等間隔に少なくとも３つ配置されているので、最小限のリブ１５の数でボルト３に対するカラー１３の中心出しを可能とし、取付部材５に対する被取付部材９のガタを小さくできると共に、カラー１３の形状を簡易化することができる。   Further, since at least three ribs 15 are arranged at equal intervals in the circumferential direction of the inner peripheral surface of the collar 13, the collar 13 can be centered with respect to the bolt 3 with the minimum number of ribs 15 and attached. The backlash of the attached member 9 with respect to the member 5 can be reduced, and the shape of the collar 13 can be simplified.

さらに、リブ１５の取付部材５側には、カラー１３の外部から内部に向けてカラー１３の径を小さくする方向に傾斜されたテーパ１７が設けられているので、取付部材５に対して被取付部材９をテーパ１７に沿って斜めに組付けることを許容し、ボルト３に対するリブ１５の引っ掛かりを防止することができ、組付性を向上することができる。   Further, since the rib 15 is provided with a taper 17 that is inclined in the direction of decreasing the diameter of the collar 13 from the outside to the inside of the collar 13, the rib 15 is attached to the mounting member 5. The member 9 is allowed to be assembled obliquely along the taper 17, the hooking of the rib 15 on the bolt 3 can be prevented, and the assembling property can be improved.
