b壁面との間に空間部3eが形成され、ボルト5,5挿入時の
爪3c,3cの撓みを助けるものである。As shown in FIG. 1, an annular raised portion 3a is formed on the surface of the bracket 3, and bolts 5, 5 are formed at the center of the raised portion 3a.
The mounting hole 3b is formed through. Further, on the inner wall surface of the mounting hole 3b, a pair of claws 3c, 3 facing each other from the periphery of the mounting hole 3b toward the center of the mounting hole 3b along the insertion direction of the bolts 5,5.
c is extended downward. Further, escape holes 3d, 3d are formed on both sides of the claws 3c, 3c to assist the movement of the claws 3c, 3c (see FIG. 2). In addition, mounting holes 3 are provided on the rear side of the claws 3c, 3c.
A space portion 3e is formed between the b wall surface and the claws 3c and 3c when the bolts 5 and 5 are inserted, to help the bending.
一方、ボルト５の軸部5aには、環状の溝5bを頭部5cに隣
接させて形成してある。On the other hand, in the shaft portion 5a of the bolt 5, an annular groove 5b is formed adjacent to the head portion 5c.
そして、ボルト5,5を取付孔3bに組み付ける場合、ボル
ト５の軸部5aをブラケット３の上方から取付孔3b内に押

なお、本実施例では、ボルト５の取付孔3bと隣接して２
個の逃げ孔3d,3dを設けて、成形中に爪3c,3cが取付孔3b
の周縁に付着するのを防止しているが、これらの逃げ孔
3d,3dは第６図に示すように省いてもよい。In addition, in this embodiment, the bolt 2 is provided adjacent to the mounting hole 3b.
The individual relief holes 3d, 3d are provided so that the claws 3c, 3c can be attached to the mounting holes 3b during molding.
It prevents them from adhering to the periphery of the
3d and 3d may be omitted as shown in FIG.
また、ボルト５の環状の溝5bに２個の爪3d,3dを係合さ
せてボルト５の抜けを阻止しているが、その個数は第７
図に示すように１つであってもよい。Further, the two claws 3d, 3d are engaged with the annular groove 5b of the bolt 5 to prevent the bolt 5 from coming off.
There may be one as shown.
さらに、本考案はドアハンドルのブラケットのほか各種
の自動車部品にも適用できることは述べるまでもない。Further, it goes without saying that the present invention can be applied to various automobile parts in addition to the door handle bracket.
f.考案の効果 本考案のボルトの固定構造によれば、部品に設けられた
ボルトの取付孔の内壁面に、取付孔の周縁からボルトの
挿通方向に沿って取付孔の中心に向かって互いに対向す

つ組み付け後はボルトが取付孔から抜けることがない。f. Effect of the Invention According to the bolt fixing structure of the present invention, on the inner wall surface of the mounting hole of the bolt provided on the part, the bolts are attached to each other from the periphery of the mounting hole toward the center of the mounting hole along the insertion direction of the bolt. Since the pair of facing claws are extended, it is easy to insert the bolt, and the bolt does not come out of the mounting hole after the assembly.
また、爪の背面側に空間部を形成したので、爪が外側に
自由に撓むのでボルトの挿入が容易である。Further, since the space portion is formed on the back surface side of the claw, the claw freely bends outward, so that the bolt can be easily inserted.
さらに、ボルトの挿入時に上記爪の先端が係合する環状
の溝を上記ボルトの軸部に形成したので、溝に爪が係合
した後は爪が外れることがない。Further, since the annular groove with which the tip of the pawl engages when the bolt is inserted is formed in the shaft portion of the bolt, the pawl does not come off after the pawl engages with the groove.
