置。 A power cylinder that generates an assist force, a steering device pump that supplies pressurized fluid to the power cylinder, and a servo valve that controls supply and discharge of pressurized fluid to the power cylinder by relative displacement between an input shaft and an output shaft. A steering force control device for a power steering device including a reaction force mechanism that changes the handle torque of an input shaft by fluid pressure introduced into a reaction force chamber,
A vehicle speed-responsive pump whose discharge flow rate increases or decreases depending on the vehicle speed is provided, and this vehicle speed-responsive pump is connected to the reaction force chamber via an introduction passage and connected to the tank via a branch passage branching from the introduction passage. ,
A flow control valve is inserted into this branch passage to control the flow rate of the pressure fluid returned to the tank from the introduction passage by a valve member that slides inside the valve body, and the flow control valve is moved relative to the vehicle according to the load capacity of the vehicle. A steering force control device for a power steering device, characterized in that the steering force control device is connected to a portion where the steering force is controlled.
