る。In the case of the present invention, when the engaging portion and the neck portion are inserted into the mounting hole of one panel material, the support flange comes into contact with the upper surface of the panel material during the insertion. Since the reduced diameter portion is provided between the flange and the bumper main body, the peripheral portion of the support flange is easily pushed up at this time, and the locking portion surely passes through the mounting hole. When the work is completed in this manner, the neck portion is completely fitted into the mounting hole, and the supporting flange and the locking portion are locked to the hole edge of the mounting hole of the panel material so as to be sandwiched therebetween.

ることはない。In the case of the present invention, even if the bumper main body is inclined by the lateral load, the lower surface side of the bumper main body is less likely to directly contact the support flange and the panel material. Therefore, even when a relatively large lateral load is input, the locking portion is not lifted up with the outer peripheral end of the bumper body as a fulcrum.
【００１４】請求項３に記載の発明は、縮径部と支持フ
ランジを曲面状に滑らかに連続させるようにした。According to a third aspect of the present invention, the reduced diameter portion and the support flange are smoothly and continuously connected in a curved shape.

More specifically, the bumper body 16
A substantially middle portion in the axial direction is a maximum outer diameter portion 16a, and the diameter is smoothly reduced in an arc from the maximum outer diameter portion 16a toward the lower end. This portion is a reduced diameter portion in the present invention, and is indicated by reference numeral 16b in the drawing. The minimum outer diameter of the reduced diameter portion 16 b is set to be larger than the outer diameter of the neck portion 17. In FIG. 1, the shape of the bumper main body 4 of the conventional bumper rubber shown in FIG. 6 is shown by a chain line so that the shape of the bumper main body 11 of this embodiment can be easily understood.

る。In the above configuration, when the bumper rubber 11 is attached to the panel member 12, first, FIG.
As shown in (A), the tip of the locking portion 15 is inserted into the mounting hole 14 of the panel member 12, and the locking portion 1 is formed using the above-described jig or the like.
5 is passed through the mounting hole 14 while being elastically deformed. At this time, the locking portion 15 is reduced in diameter while being inclined at the upper end by the pushing force applied to the bumper rubber 11, and is further inserted into the mounting hole 14 together with the neck portion 17 in that state. When the locking portion 15 and the neck portion 17 are inserted into the mounting hole 14 to some extent, the support flange 1
8 is brought into contact with the upper surface of the panel material 12 and a pushing force is further applied to the bumper rubber 11.
As shown in (B), the support flange 18 is pushed upward, and the entire locking portion 15 completely passes through the mounting hole 14.

方に持ち上げられるようなことはない。Thus, the bumper rubber 11 attached to the panel member 12 is attached to the neck portion 17 of the bumper body 16.
A reduced-diameter portion 16b is provided at the end on the side, and the panel member 12 is abutted and supported by a thin supporting flange 18. As shown in FIG. Even when the directional load P is applied, the bumper main body 16 only inclines mainly around the reduced diameter portion 16b as shown by the broken line in FIG. Nothing can be lifted.

ることができる。That is, since the reduced diameter portion 16b is provided at the lower end of the bumper main body 16, the lower surface of the bumper main body 16 does not directly contact the support flange 18 or the panel member 12 due to the input of the lateral load. Therefore, no force acts on the bumper rubber 11 to lift the locking portion 15 to one side with the outer peripheral end of the bumper body 16 as a fulcrum. In particular, in this embodiment, the reduced diameter portion 16
b is formed so as to be gradually reduced in an arc shape from the maximum outer diameter portion 16a of the bumper main body 16, so that even when a relatively large lateral load is applied to the bumper main body 16, It is possible to reliably prevent the maximum outer diameter portion 16a from directly contacting the support flange 18 and the panel member 12.

５の持ち上がりを防止できる。Further, since the bumper body 16 is continuous with a gentle curved surface from the reduced diameter portion 16b of the bumper body 16 to the support flange 18, even if a lateral load P is applied to the bumper body 16, the diameter of the reduced diameter portion is reduced. 16b can be prevented from buckling deformation. Therefore, it is possible to prevent the bumper main body 16 from extremely falling down and to prevent the bumper main body 16 from directly contacting the support flange 18 and the panel member 12 so that the locking portion 1 is formed.
5 can be prevented from lifting.
