Abstract
A peripheral wall of a rectangular pedestal is formed bulged on the rear wall of a booster shell and attached to a vehicle body by four connecting bolts. The wall is comprised of a pair of shorter side walls parallel to shorter sides of the rectangle connecting axes of the four connecting bolts, a pair of longer side walls each bent so as to be gradually separated farther from the corresponding longer side of the rectangle at a central portion than at an end portion thereof, and four arcuate corner walls with each corner wall connecting the adjacent shorter and longer side walls. Thus, an intermediate portion of the longer side wall of the pedestal is increased in rigidity, so that an increased burden of stress can be imposed on such longer side wall. This moderates the stress concentration around the corners, thereby improving the durability of the booster shell.
