ABSTRACT:
A rack and pinion type steering apparatus in accordance with the present invention is provided with a rack guide made of synthetic resin. On the outer periphery of the rack guide is disposed a taper-form rib extending from the topmost portion of both outer sides of a concave one end-surface toward the portion of both outer sides of the other end-surface of the axial direction. The width of the rib becomes greater as it goes from the other end-surface of the axial direction toward one end-surface which is engaged with the back surface of the rack shaft. As a result, the concave portion of the one end-surface of the axial direction is hard to shrink inwardly when being molded, thereby the diameter of the one end-surface of the axial direction and that of the other end-surface of the axial direction of the rack guide are substantially the same.
