Claims

[Scope of utility model registration request]

In a steering force control device for a power steering device that includes a control valve that controls a power cylinder based on steering and a hydraulic reaction force device that controls steering force, a reaction force passage is provided in a reaction force chamber of the hydraulic reaction force device. a vehicle speed sensitive pump that supplies hydraulic pressure in accordance with the vehicle speed through the gear passage; a steering pump that supplies a certain amount of pressure oil to the control valve through the gear passage; and a steering pump that supplies hydraulic pressure in accordance with the vehicle speed to the reaction passage. A control orifice for generating the force, a throttle passage communicating the reaction force passage and the gear passage, and a relief valve for setting the upper limit pressure of the vehicle speed sensitive pump, the relief valve being disposed near the power steering device. A steering force control device for a power steering device, characterized in that:
