VEHICLE BODY STRUCTURE AT A REAR PORTION OF A VEHICLE

摘要

A side frame 1 of a grooved or channel-shaped sectional configuration has a bottom wall 2 and sidewalls 3 and 4. A first stiffener 9 closing a portion of an open upper surface of the side frame 1 and a second stiffener 10 superposed on the bottom wall 2 are welded to the side frame 1 to reinforce the side frame 1. A cup-shaped spring base 11 is fitted from below into and welded to openings 2 1 and 10 3 defined in the bottom wall 2 and the second stiffener 10, and an upper end of a coil spring 19 is accommodated within the spring base 11. The side frame 1, which is reduced in rigidity due to the opening 2 1 can be reinforced with the first and second stiffeners 9 and 10, whereby a sufficient rigidity of the side frame can be ensured.
