PROBLEM TO BE SOLVED: To provide a suspension device for a rear wheel, which suppresses or cancels influence of a vertical force compliance steering at the beginning of turning.SOLUTION: A suspension device comprises: a housing which supports a rear wheel of a vehicle rotatably around an axis; links in which both endpoints are respectively swingably attached to a vehicle body and a hub bearing so that the housing is strokably supported with respect to the vehicle body; a spring which generates a reaction force according to relative displacement amount with respect to the vehicle body in the vertical direction; and a damper which generates a damping force according to a relative speed of the housing with respect to the vehicle body in the vertical direction. 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 suspension device includes toe change generation means temporarily generating a toe change of which direction temporarily cancels or suppresses a toe change caused by the vertical force compliance characteristics at the beginning of turning of the vehicle so that the damper in the side of the turning outer wheel is compulsory moved toward the compression side. |
