    Abstract: Disclosed is a rack bar supporting device of a rack and pinion type steering apparatus for a vehicle. The disclosed device can prevent free movement from increasing by automatically adjusting a predetermined free movement even when wear occurs in a support yoke after degradation of driving durability of the vehicle, and can prevent a noise from occurring caused by an increase of free movement when the support yoke collides with a yoke plug by an impact reversely input from an uneven road surface, etc. This can provide a comfortable steering feeling to the driver.

    Abstract: Disclosed is a sealing part structure of a cylinder tube disposed in a hydraulic power steering apparatus. The sealing part structure includes an oil seal for preventing leakage of power steering oil; a DU bushing for guiding a reciprocal movement of a rack bar in a leftward and rightward direction; a rack bush for absorbing a shock from a piston disposed in the rack bar; a stop ring for fixing the rack bush to a cylinder tube. According to the present invention, the number of parts is reduced, thereby simplifying an assembling process as well as reducing a manufacturing cost thereof so as to improve productivity.
