摘要

The structure has a pair of right and left rear underframes (18) attached to two side chassis (13), and a pivot bolt (45) supported by pivot plates (36) provided between the two side chassis and the underframes. Each of the two side chassis is obtained by folding and shaping a single tube. The two side chassis, a central chassis (14), a U-shaped section (32) of a connection chassis (17) and the underframes are disposed, so that they are juxtaposed by pairs in front of, under, and behind a step plate (26).
