Abstract: A rolling body retaining member comprising, based on the whole weight thereof, 15 to 50 wt. % of glass fiber or like reinforcing fiber, 5 to 15 wt. % of carbon powder, and the balance polyether ether ketone resin.

Abstract: A housing has accommodated therein a hollow cylindrical rack guide made of synthetic resin and pressed against a rack bar by a spring for guiding the rack bar and preloading the rack relative to the pinion, the rack guide being formed in its one end face with a guide groove for guiding the rack bar.

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.
