Abstract

A suspension structure (100) includes: a chassis frame including a pair of side frames (12); leaf springs (20); and brackets (22, 24). One end of the leaf spring (20) is attached to an outer side surface (12f) of the side frame (12) through the bracket (22). The other end is attached to a lower surface of the side frame (12) through the bracket (24). The bracket (22) is fixed to a first position (P1) located in the side frame (12), and the bracket (24) is fixed to a second position (P2) at which a distance between the side frames (12) in the width direction of the vehicle is larger than the distance between the side frames (12) at the first position (P1).
