Abstract

PROBLEM TO BE SOLVED: To provide a shock absorbing effect by means of a simple and low- cost arrangement by permitting a shock imposed on a bumper to be absorbed by a mounting part for mounting on a frame member. SOLUTION: In a bumper mounting structure, a bottomed, cylindrical mounting portion 7 whose bottom serves as a mounting seat 9 is formed to project from the bumper 1 toward the frame member 14 of a vehicle body, with the mounting seat 9 fastened to the frame member 14. A shock restraining portion 13 such as a thin-walled portion 12 formed of a notch 11 is provided at the cylindrical section 8 of the mounting portion 7, so that when a shock not smaller than a predetermined value is imposed on the bumper 1, the relative movement of the bumper 1 toward the frame member 14 is permitted by the rupturing of the thin-walled section 12 or the like to absorb the shock.

Further, since the mounting portion 7 is provided with the above-described impact suppressing portion 13, there is no need to separately provide an impact absorbing member or a complicated impact absorbing structure, and the configuration can be made at low cost. When the impact suppressing portion 13 is formed by the thin portion 12 formed by the notch 11 formed in the cylindrical portion 8 of the mounting portion 7 as described above, the front bumper 1 can be formed without a complicated mold structure at the time of molding, and the cost is further reduced. And there is no sudden change in the overall shape of the cylindrical portion 8 to reduce the rigidity. Therefore, even if the impact suppressing portion 13 is provided, the mounting rigidity of the front bumper 1 in a normal state is high, which may cause vibration. There is no.

In the above description, an example is shown in which the cylindrical portion 8 has a truncated pyramid shape, but it may have a truncated cone shape. But,
A truncated pyramid shape provides higher mounting rigidity. In addition, although the impact suppressing portion 13 is constituted by the thin portion 12 formed by the notch 11, the cylindrical portion 8 is formed as shown in FIG.
May be constituted by a thin step portion 20 formed at an intermediate position between the two. By making the width dimension w of the thin step portion 20 slightly larger than the wall thickness t of the cylindrical portion 8 to reduce the width dimension of the thin portion, the impact more than a predetermined impact can be obtained while normally securing the mounting rigidity. When it is applied, it can be broken smoothly to absorb the impact. Further, by appropriately forming a slit in the thin portion of the thin step portion 20, the breaking impact amount can be arbitrarily set. In addition, the thin step 20
May be constituted by an inclined step portion.
