ABSTRACT:
In a rack and pinion power steering apparatus including a hydraulic cylinder housing, a pinion, a rack, a piston, a bolt for mounting the piston to the rack, etc., the piston is elastically supported by the bolt to a boss portion of the rack concentrically with respect to the rack at a position offset from the longitudinal axis of the rack in the opposite direction of the rack teeth. Therefore, it is possible to form a threaded hole, into which the piston mounting bolt is screwed, in the boss portion extending under the bottom surface of the rack teeth, thus reducing the longitudinal direction of the rack or cylinder housing to realize a small-sized power steering apparatus.
