ングの操舵力制御装置。 An oil passage that communicates between the hydraulic pump and a control valve that supplies hydraulic pressure to the power cylinder; and a bypass that is branched from the oil passage via an orifice and communicates each of the hydraulic reaction force sections on both sides of the control valve with a reservoir tank. A power steering steering force control device including an oil passage and a flow rate adjustment valve that is provided in the bypass oil passage and is operated by a control signal based on a vehicle speed detection signal to adjust the oil flow rate, the bypass oil The power supply is characterized by comprising a shutoff valve that is provided upstream of the hydraulic reaction force section of the passage and operates in a direction to shut off the bypass oil passage in response to a control signal based on a detection signal of a predetermined vehicle speed or higher. Steering force control device.
