取装置。 an input shaft whose outer end side is connected to the steering wheel side and whose inner end side is inserted into the housing and connected to the steering wheel side via a steering gear mechanism; A flow path between the left and right chambers of the fluid pressure cylinder, the pump, and the tank, which has a valve spool that is connected in series and is actuated by the movement of the input shaft in the axial direction to apply a steering assist force to the steered wheels. A control valve that switches and controls the control valve according to the steering operation, and one of a pair of left and right reaction plungers that are arranged equally around the control valve in the housing and formed by a reaction spring are formed in the housing. A reaction force spring mechanism is provided which applies a force to return the input shaft to the neutral position in the axial direction by bringing the input shaft side into contact with the locking surface that has been applied to the input shaft. A power steering device characterized in that a relief groove is provided in a locking surface in the housing that one of the left and right reaction force plungers abuts.
