ABSTRACT:
A rear wheel steering hydraulic cylinder is arranged in a rear wheel steering apparatus to steer rear wheels to the right and left. When a front wheel steering angle detected by a front wheel steering angle sensor exceeds a predetermined value, the hydraulic cylinder is actuated to steer the rear wheels in a direction opposite to that of the front wheels. When the rear wheel steering angle detected by a rear wheel steering angle sensor is changed in response to the front wheel steering angle, the hydraulic cylinder is not activated, thereby not steering the rear wheels.
