SUSPENSION DEVICE

A suspension device installed in a vehicle includes a motor, a torsion bar, a linking member, and a support member. A first portion of the torsion bar is linked to an output shaft of the motor. The linking member is configured to link between a second portion of the torsion bar and an unsprung member. The support member is configured to support the motor on a sprung structure via a first elastic member, and is disposed such that the motor and the torsion bar integrally turn in a direction orthogonal to a first direction, about a position of the support member as a center of turning. The first direction is an axial direction of the torsion bar.
