Abstract: Disclosed is a rack bush and a rack pinion type steering apparatus having the rack bush for a vehicle, which can smoothly support a load in an axial direction and a vertical direction of a rack bar so that it is possible to reduce abnormal abrasion of the rack bush, reduce a rattle noise caused by external force transferred through the rack bar during movement of the rack bar, and prevent damage to the rack bar and a pinion through distribution of the load due to an external impact on the shaft.

Abstract: A hydraulic power steering apparatus for a vehicle is disclosed. The hydraulic power steering apparatus for a vehicle forms a working fluid film between a piston reciprocating within a cylinder tube and a piston ring in order to provide an accurate auxiliary steering force by preventing leakage of a working fluid between right and left cylinders during the operation of a steering wheel by the driver.
