装置。 Reaction force chambers are formed at both ends of a valve spool slidably housed in the valve cylinder, and communication passages connecting the respective reaction force chambers and the respective cylinder chambers are connected through first and second orifices, respectively. One reaction force chamber communicates with one cylinder chamber through the first orifice, and a third reaction force chamber communicates with the other cylinder chamber through the first orifice.
In a power steering device equipped with a control valve that communicates with each cylinder chamber through an orifice, the flow coefficients of the first and third orifices that communicate with each cylinder chamber are the same regardless of the flow direction of the hydraulic fluid. A power steering device that is provided with a resistance member that causes
