ことを特徹徴とする動力操向装置。 When a relative rotational displacement occurs between an input member rotatably supported by a bearing within a housing and an output member rotatably supported by a bearing within a gear housing fixed to the housing,
Power for selectively supplying and discharging hydraulic oil to two working chambers in a power cylinder separated by a piston using a hydraulic control mechanism to assist the steering operation of a steering member connected to the piston. In the steering device, a through hole that penetrates the gear housing inwardly and outwardly is formed in a portion of the gear housing that corresponds to the small diameter portion formed at the end of the output member, and the small diameter portion of the output member is inserted into the through hole. A rolling bearing rotatably supported is arranged, and the rolling bearing is pressed in the axial direction of the input member and the output member, so that the axial direction of the input member and the output member within the housing and the gear housing is A power steering device characterized in that an axial adjustment mechanism for adjusting play is disposed at the opening of the through hole.
