徴とするパワーステアリング装置。 A power cylinder that operates to assist steering operations by controlling the supply and discharge of oil from the pump, and a hydraulic system that functions to increase resistance to steering operations by increasing hydraulic pressure when driving at high speeds. A power steering device comprising a reaction force mechanism and a diversion valve that distributes oil sent from the pump to the power cylinder and the hydraulic reaction mechanism so that the hydraulic reaction mechanism side is given priority, the power steering device according to the above. Valve control that receives a signal based on the hydraulic reaction mechanism in a state where the hydraulic reaction force mechanism does not require oil pressure, and operates to throttle the port of the branch valve that communicates with the hydraulic reaction mechanism and open the port that communicates with the power cylinder side. A power steering device characterized by being equipped with a mechanism.
