In a rear wheel suspension system whose front and rear ends are attached to vehicle body members via bushings made of an elastic material such as rubber, the side support members are pivotably attached to both sides of a cross member, and the front end of the side support member The attachment point of the side support member to the vehicle body member is set to a position offset outwardly from the vehicle side by a predetermined amount with respect to the axis attachment point of the side support member to the cross member, and the cross member is pressed and displaced in the left-right direction in response to front wheel steering. A rear wheel steering device for a vehicle, characterized in that it is provided with an actuator that causes the vehicle to rotate.
