摘要： A torque detection device has a magnetic flux collecting ring, arranged outside an outer periphery of a magnetic circuit forming member which is provided in a rotating body applied with a torque, for collecting a magnetic flux generated by the magnetic circuit forming member; a detector for detecting the torque applied to the rotating body based on a density of the magnetic flux collected by the magnetic flux collecting ring; and a holding ring for holding the magnetic flux collecting ring and the detector and including an attachment part to be attached to a stationary object on an outer periphery on one side in a radial direction. An attachment-preventing convex part for preventing attachment to the stationary object by contacting the stationary object is formed on one end face in an axis line direction of the holding ring.

摘要： A hydraulic power steering device responsive to the speed of a vehicle and comprising a housing, an output shaft disposed in the housing, an input shaft disposed in the housing and coaxial with the output shaft, a torsion bar 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 each slidably fitted in a hole 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 slidable in contact with the inner peripheral surface of the output shaft defining the hole and the portion of the plunger to be pressed into contact with the input shaft is made of a synthetic resin.
