量を得ることができる。 The present invention consists of the above-mentioned structure. When an impact is applied to the bumper skin during a car collision, the load is transmitted from the skin vertical wall of the bumper skin to the spacer vertical wall, causing the energy absorbing part of the spacer to collapse. The energy absorbing portion is fitted into the spacer fixing hole 7 while the portion is cut into the spacer fixing hole. The resistance force of cutting and fitting at this time becomes the energy absorption amount of the impact. Therefore,
The energy absorbing portion can reduce the energy at the time of a collision, and an appropriate amount of energy absorption can be obtained simply by changing the cross section of the absorbing portion of the resin spacer.
