Claims

[Claims for Utility Model Registration] A power steering device having an input shaft connected to a main shaft via a torsion bar, and a cylinder interlocked with the main shaft and provided with first and second oil chambers at the front and rear in the direction of movement, A large-diameter cylindrical portion integrally provided with the main shaft and formed to cover the outer periphery of the input shaft, a drive ring fitted on the outer periphery of the large-diameter cylindrical portion, and an input shaft provided on the outer periphery of the input shaft. a long groove provided so as to extend along the axial direction of the input shrad; A through hole is provided, one end of which is fixed to the drive ring and the other end of which is engaged with the long groove;
At least one of the following: a lower live pin whose intermediate portion engages with the through hole, a barley pool valve that engages with the drive ring and is arranged so that its axis extends along the axial direction, and the spool valve. The spool valve is provided with an elastic member disposed so as to press the front end face, and which moves the drive ring in the axial direction by the relative rotation between the input shaft and the main shaft caused by the rotation of the input shaft. move it. A power steering jig device characterized in that oil from a hydraulic pressure supply source is selectively supplied to the first oil chamber or the second oil chamber.
