置。 A rotary valve is constituted by a first valve member provided on the input shaft and a second valve member provided on the output shaft, and further,
The input shaft and output shaft are connected by a torsion bar, and by twisting the torsion bar, the two shafts are rotated relative to each other, and the switching amount of the rotary valve is controlled according to the amount of relative rotation, thereby operating the power cylinder. In the power steering device, a plurality of spherical grooves are formed around the input shaft, and the output shaft or a second valve member provided on the output shaft fits into the spherical grooves when the handle is in a neutral position. In addition to providing multiple balls,
A power steering device in which a pressing force of an elastic body is applied to this ball to press it against the spherical concave groove side.
