この発明は、バンパ取付構造に係り、特に、合
成樹脂、ゴム等で成形した樹脂バンパをバンパー
ステーで車体に取付ける構造に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bumper mounting structure, and more particularly to a structure in which a resin bumper molded from synthetic resin, rubber, etc. is mounted to a vehicle body using a bumper stay.

している。 As shown in Fig. 1, the bumper B is attached to the front and rear of the vehicle body by bumper stays S. Conventional bumper B is the one shown in Utility Model Application No. 52-136344, or the one shown in Fig. 2. As shown, the attachment between the bumper B and the bumper stay S is achieved by providing attachment portions 9 that protrude vertically at the tip of the bumper stay S, and connecting these attachment portions 9 to the upper wall 3 and lower wall of the bumper B. 4 are fixed by bolts 7 and nuts 8, such as ornamental bolts or ordinary hexagonal bolts.

Ｓが取付けられることから制限されていた。 However, in the conventional bumper B, since the upper wall 3 and lower wall 4 are fixed to the mounting part 9 formed at the tip of the bumper stay S, the mounting part 9 is attached to the upper wall 3 and the lower wall 4. Moreover, the upper wall 3 and the lower wall 4 are not necessarily formed substantially parallel to each other, which makes it difficult to cut the bumper stay S into the board. In addition to the problem of increased parts cost, the shape of the upper wall 3 and lower wall 4 was also limited because the bumper stay S was attached.

た。 In addition, resin bumpers molded from synthetic resin, rubber, etc. have a higher coefficient of thermal expansion than metal bumpers, and when bumper B is fixed to a pair of left and right bumper stays S as in the conventional bumper mounting structure, these Since there is no escape between the bumper stays S, it is not possible to absorb large contractions and expansions of the resin bumper in cold or tropical regions or when there is a large temperature difference, and there is a risk that the resin bumper may become distorted or deformed. It was hot.

る。 In Figure 1, a pair of left and right bumper stays S
A resin bumper B is shown attached to the vehicle body with this bumper stay S. In this embodiment shown in FIGS. 3 and 4, the bumper stay S
is formed into a substantially U-shaped cross section with flange portions 5 at the upper and lower ends by bending the upper and lower ends of a substantially rectangular steel plate in the same direction, respectively, and these flange portions 5 A round hole 6 for fixing the resin bumper B is bored in the hole.

されている。 On the other hand, the resin bumper B attached to the vehicle body by the bumper stay S has an interval between the upper wall 3 and the lower wall 4 on the back side of the resin bumper B, which is large enough to allow the tip of the bumper stay S to be tightly fitted. A pair of mounting feet 1 protruding approximately parallel to each other are integrally molded, and a bumper stay S is attached to these mounting feet 1.
A long hole 2 is bored along the longitudinal direction of the resin bumper B, corresponding to the round hole 6 bored in the flange portion 5 of the resin bumper B.

われている。 Also, to install the resin bumper B and the bumper stay S, fit the tip of the bumper stay S between the pair of mounting legs 1, align the elongated hole 2 with the round hole 6, and insert this length into the elongated hole 2. This is done by attaching a collared washer 10 movable in the longitudinal direction of the hole 2, inserting the bolt 7 from the elongated hole 2 into the round hole 6 through the collared washer 10, and tightening it with the nut 8. ing.

増してデザイン上好都合である。 Therefore, according to the bumper mounting structure of the present invention,
The bumper stay S has flange parts 5 at the upper and lower ends.
Because it is formed in a substantially U-shaped cross section,
It can be easily manufactured from a steel plate cut into a substantially rectangular shape, and complete cut-out with no waste is possible, making it possible to reduce the parts cost of the bumper stay S. In addition, as in the case of the above embodiment, a pair of mounting feet 1 are provided on the back surface of the resin bumper B.
If the resin bumper B is installed on the tip of the bumper stay S using these mounting feet 1, the mounting members such as bolts and nuts can be completely hidden behind the resin bumper B. In addition to improving the appearance of the resin bumper B, the degree of freedom in shaping the upper wall 3, lower wall 4, etc. of the resin bumper B increases, which is advantageous in terms of design.

る。 Furthermore, even if the resin bumper B contracts or expands significantly in cold regions, tropical regions, or regions with large temperature differences, the resin bumper B and bumper stay can By attaching the bumper stays to the bumper stays S through the long holes 2 drilled on either side of the bumper stays, changes in the length between the pair of bumper stays S due to contraction or expansion can be prevented by the long holes 2. This can prevent the resin bumper B from becoming distorted or deformed.
