グ装置。[Claims for Utility Model Registration] A housing, an output shaft disposed within the housing, an input shaft disposed within the housing on the same axis as the output shaft, and an output shaft disposed between the output shaft and the input shaft. A torsion bar, a control valve that is installed around the input shaft and controls the amount of pressure oil sent from the hydraulic pump to the power cylinder according to the torsion of the torsion bar, and a control valve that is slidably fitted into a hole formed in the output shaft. In a vehicle speed-responsive hydraulic power steering device, the plunger has a plunger inserted therein, and the tip of the plunger is pressed against the input shaft by hydraulic pressure according to the vehicle speed to obtain a reaction force. Consists of a synthetic resin main body and a metal ring that is fixed to the peripheral surface of the main body and whose outer peripheral surface is in sliding contact with the hole in the output shaft, and has one end of the main body that protrudes beyond the metal ring and contacts the input shaft. A vehicle speed-responsive hydraulic power steering device in which a convex portion is formed and a recess into which the convex portion can fit is formed at the other end.
