To restrain influence of rigidity in the axial rectangular direction of a coil spring on positional adjustment of a tire.
A shape of this spring seat is made to make rigidity in the axial direction of the spring seat less than the rigidity in the axial rectangular direction of the coil spring. Materially, the spring seat 10 is constituted of a roughly flat plate disc shape main body part 11 and a disc shape projected part 12 integrally formed on the main body part 11 along an inner periphery of a lower side surface of the main body part 11. Thereafter, thickness in the axial rectangular direction (diametrical direction) of the coil spring 4 on the projected part 12 is made less than thickness in the axial direction of the coil spring 4 on the main body part 11.
