A suspension device for a vehicle includes a spring device disposed between a sprung member and an unsprung member of a vehicle and allowing a relative displacement between the sprung member and the unsprung member. The spring constant k2c of the spring device when the spring device is deformed in the direction in which the spring device contracts with respect to the predetermined reference length is configured to be smaller than the spring constant k2e of the spring device when the spring device is deformed in the direction in which the spring device expands with respect to the predetermined reference length. Consequently, it is possible to obtain a characteristic opposite to the spring characteristic of the seat, and as a result, ride quality can be improved.
