PROBLEM TO BE SOLVED: To make a head-turning property at low lateral force and stability at high lateral force compatible, by suitably controlling a lateral steering phenomenon. SOLUTION: When a vehicle turns, centrifugal force is generated outward in a turning direction, and lateral force inward in the turning direction acts on a rear wheel W so as to resist to the centrifugal force. In case that the lateral force is less than a predetermined value, a rubber bush joint 30 on a front side and a rubber bush joint 32 on a rear side uniformly displace, so that the generation of the lateral steering phenomenon can be suppressed, and the turning property of the head-turning property of the vehicle can be ensured. In case that the lateral force is not less than the predetermined value, the rubber bush joint 30 becomes larger than the displacement amount of the rubber bush joint 32, so that the rear wheel W on the outside in the turning direction is steered in a toe-in direction by the difference of the displacement amount, and the rear wheel W on the inside in the turning direction is steered in a toe-out direction to stabilize the behavior of the vehicle.
