ABSTRACT:
A power steering apparatus includes a pair of projections formed on the input and the output side, respectively, and also includes a substantially C-shaped spring disposed in surrounding relationship with the input shaft so that the both projections are maintained in their neutral position. In the neutral position, a circumferential clearance between the end faces of a notch formed in the spring and the projections is maintained substantially zero. The projection formed on the input side engages the lateral side of an inner race of a bearing which rotatably carries the input shaft, thereby preventing a withdrawal of the input shaft. Hydraulic fluid used in the control valve is utilized to define a hydraulic bearing between the input and the output shaft.
