A suspension includes: wheel supporting members for supporting wheels, a leaf spring having both end portions each arranged on an upper side of the respective wheel supporting member; a pivot supporting the leaf spring, and receiving pieces interposed between the wheel supporting members and the both end portions of the leaf spring respectively. Each of the wheel supporting members includes a recess portion on which one of the receiving pieces is mounted. Each of the receiving pieces includes an engaging portion for engaging with one of the both end portions of the leaf spring. Each of the receiving pieces includes an elastic member and a first metal plate joined on the elastic member. The elastic member can deform to follow a displacement of a relative position between the leaf spring and one of the wheel supporting members.
