摘要： A hydraulic power steering device responsive to the speed of a vehicle and comprising a housing (30), an output shaft (31) disposed in the housing, an input shaft (33) disposed in the housing and coaxial with the output shaft, a torsion bar (34) provided between the output shaft and the input shaft, a control valve provided around the input shaft for controlling the amount of pressure oil to be supplied from a hydraulic pump to a power cylinder in accordance with the torsion of the torsion bar, and plungers (1) each slidably fitted in a hole (32) formed in the output shaft, each of the plungers being adapted to be pressed at its forward end against the input shaft by oil pressure in accordance with the vehicle speed to obtain a reaction. At least one of the portion of the plunger (1) slidable in contact with the inner peripheral surface of the output shaft defining the hole (32) and the portion of the plunger to be pressed into contact with the input shaft (33) is made of a synthetic resin.
