持つ車両のステアリング装置。 a power steering gear box, a control valve interlocked with the power steering gear box, a switching means for switching the flow of pressure oil from a hydraulic source in conjunction with the steering handle, and a control valve that is driven by the pressure oil and that controls the steering handle. In a steering device for a vehicle having four turnable wheels, which is equipped with a hydraulic cylinder or the like that changes the direction of the wheels in response to rotation, a rear wheel turning system takes out hydraulic pressure for rear wheel turning between the hydraulic power source and a control valve. A steering device for a vehicle having four turnable wheels, characterized in that a switching valve for supplying pressure oil to a rear wheel hydraulic cylinder when the hydraulic switching valve is switched is provided.
