A second throttling control valve is installed in series with the valve, a vehicle speed pump is rotatably driven by the vehicle's drive system and rotates in proportion to the vehicle speed, and the vehicle speed pump is driven in response to a signal oil pressure supplied from the vehicle speed pump. A hydraulic actuator is provided to control and drive the second throttle control valve so that when the signal oil pressure is low, the rear wheels are steered in the opposite direction to the front wheels, and when the signal oil pressure is high, the rear wheels are steered in the same direction as the front wheels. A four-wheel steering device characterized by comprising:
