特徴とする車両用動力舵取装置。A control valve that operates in response to the handle operating force to supply and discharge pressurized oil discharged from the hydraulic pump to the power cylinder, and a pressure chamber that is pressed by the hydraulic pressure applied to it and transmits a reaction force to the handle side. In the power steering device for a vehicle comprising a hydraulic reaction force mechanism having a hydraulic reaction force mechanism, an inflow port connected to the hydraulic pump and the reaction force are connected in a supply oil path connecting the inflow port of the hydraulic pump and the control valve. The first connected to the force chamber
a flow rate regulating valve having a flow outlet and a second outlet connected to the inlet of the control valve and allowing a small constant flow rate to flow to the first outlet and a remaining amount to the second outlet; A variable throttle valve that throttles the oil passage according to the vehicle speed is provided in a branch oil passage branching from the discharge oil passage connecting the first outlet of the flow rate adjustment valve and the reaction force chamber and connected to the reservoir; A power steering device for a vehicle, characterized in that a fixed throttle is provided in an oil passage connecting a second outlet of a flow rate regulating valve and an inlet of the control valve, and a connecting oil passage connecting the discharge oil passage.
