置。A power steering device that sends hydraulic fluid from a hydraulic pump to a power steering actuator depending on the direction of steering wheel switching includes a vehicle speed sensor that detects vehicle speed and a flow path for hydraulic fluid that decreases as the vehicle speed increases. A power steering device characterized by comprising a control valve, a flow rate control device that throttles the oil discharged from the hydraulic pump in response to an increase in pump rotation speed, and means for canceling the restriction during high rotation at least in a low vehicle speed range. .
