ことを特徴とする動力舵取装置。 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 a neutral position in the axial direction on the input shaft side by a reaction spring via a reaction plunger arranged equidistantly around the control valve in the housing. The input shaft is provided with a plurality of reaction force spring mechanisms that apply a return force to the input shaft, and these reaction force spring mechanisms are divided into two sets so as to apply a biasing force only to one of them in the axial direction of the input shaft, A power steering device characterized in that each reaction spring has a different set load.
