PROBLEM TO BE SOLVED: To provide a suspension device for a rear wheel, which can suppress or cancel influence of a vertical force compliance steering at the beginning of turning.SOLUTION: A suspension device comprises: a hub bearing housing which supports a rear wheel of a vehicle rotatably around an axis; suspension links by which the hub bearing housing is strokably supported with respect to the vehicle body; a suspension spring; a damper which generates a damping force according to a relative speed of the hub bearing housing with respect to the vehicle body in the vertical direction; and a rear wheel steering actuator 131 which gives a steering angle to the rear wheel. The suspension device has the vertical force compliance steering characteristics in which the rear wheel is steered in the toe-in side or toe-out side according to increase of a vertical force applied to a rear wheel tread. The rear wheel steering actuator 131 temporarily gives the rear wheel the steering angle of which direction cancels or suppresses a toe change caused by the vertical force compliance characteristics at the beginning of turning of the vehicle. |
