る動力舵取装置。 An input shaft whose outer end is connected to the steering wheel and which is inserted into the housing and whose inner end is connected to the steering wheel via a steering gear mechanism, and which is integrally connected to the tip of the input shaft inside the housing. left and right chambers of a fluid pressure cylinder and a pump, each having a valve spool provided therein and actuated by movement of the input shaft in the axial direction to apply a steering assist force to the steering wheel side;
A control valve that switches and controls the flow path between tanks according to steering operations, and one of a pair of left and right reaction plungers arranged equally around the control valve in the housing and formed by a reaction spring is connected to the input shaft. It is equipped with a reaction spring mechanism that applies a force to return the input shaft to the neutral position in the axial direction by contacting the input shaft, and is partitioned by left and right reaction plungers that constitute this reaction spring mechanism. A communication passage is provided to communicate the chamber in which the force spring is installed with one chamber of the fluid pressure cylinder that communicates with the pump side when the input shaft is operated in a direction in which axial thrust due to back pressure acts on the input shaft. A power steering device characterized by:
