。 A control valve consisting of an input shaft rotated by a steering handle, an output shaft arranged on the same axis as the input shaft and rotatable relative to the input shaft, and valve members each rotatably provided on each of these shafts. and a reaction force mechanism provided between the two shafts,
This reaction force mechanism includes a radial hole formed in one of the two shafts, a reaction plunger slidably fitted into the hole, and an inner end surface of the reaction plunger with an outer diameter of A power steering system comprising a ball held in a recess provided eccentrically from the center and an axial groove formed on the outer surface of the other shaft into which the ball is pressed by hydraulic pressure acting on the reaction plunger. A power steering device characterized in that an orifice is formed between the radial hole and the reaction force plunger, the amount of restriction of which changes depending on the amount of displacement of the reaction force plunger within the radial direction hole.
