Claim:
A rack bar supporting device of a steering apparatus for a vehicle, the rack bar supporting device comprising: a support yoke inserted in a cylinder of a gear box, which has a front side surface closely supporting a rear surface of a rack bar; a cam block having a communicating hole formed in a center thereof, which has a front side surface closely contacting with the support yoke, and a rear side surface formed with slant surfaces symmetrical to a central axis surface; sliders formed with slant surfaces corresponding to the slant surfaces of the cam block at a front side of the sliders, wherein the sliders are separately formed symmetrically to the central axis surface, the sliders have inside grooves formed at separated surfaces of the sliders, the inside grooves are coupled with elastic supports, and the sliders are movable along the slant surfaces of the cam block by an elastic force of the elastic supports applied in a direction that is from a central axis to an outer circumference so as to support the cam block in a front direction; a yoke plug coupled with the cylinder of the gear box to support rear surfaces of the sliders in the front direction, in which in a center of the yoke plug, a through hole corresponding to the communicating hole of the cam block is formed; a slider adjuster which is insertedly coupled in the communicating hole and the through hole, in such a manner that one side of the slider adjuster is supported by a front side of the cam block, and the other side is supported by a rear side of the yoke plug so as to adjust a radial directional position of the sliders.
