力操向装置。 Inside the spool valve accommodating part provided in the housing, which has an input member driven by the steering operation force and an output member that gives the steering force to the wheels, two working chambers in the power cylinder separated by a piston are respectively installed. A spool valve for selectively supplying and discharging hydraulic oil is slidably inserted in the axial direction, and the input member and the output member are inserted into the radial drive pin insertion hole provided in the spool valve. In the power steering device, a drive pin is inserted into the spool valve to move the spool valve in the axial direction according to relative rotation between the spool valves, and the spool valve includes oil passages communicating with a hydraulic pump and a reservoir tank, respectively. At the same time, a damper chamber is formed between one end of the spool valve and a sealed end formed in the spool valve accommodating portion, and the damper chamber and the oil passage are connected to each other when the spool valve is moved in the axial direction. 1. A power steering device characterized by having an orifice communicating therewith which causes resistance to the power steering device.
