摘要： 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.

摘要： 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. The rack guide is shaped in the form of a double cylinder having an inner cylindrical portion and an outer cylindrical portion by being formed in the other end face thereof with a circular spring accommodating cavity and an annular groove positioned around the cavity concentrically therewith, a plurality of ribs being formed in the annular groove between the inner and outer cylindrical portions diametrically thereof and including ribs parallel to the guide groove, the inner cylindrical portion having an end face flush with or projecting beyond the end face of the outer cylindrical portion, at least the ribs parallel to the guide groove each having an end face flush with the end face of the inner cylindrical portion.
摘要翻译：壳体容纳有由合成树脂制成的中空圆柱形齿条引导件，并通过用于引导齿条的弹簧并相对于小齿轮预加载齿条的弹簧压靠在齿条上，齿条引导件在其一个端面中形成有导向件用于引导齿条的槽。齿条引导件通过在其另一端面上形成有圆柱形部分和外圆柱形部分的形式形成双圆柱体，该圆柱体引导件具有圆形弹簧容纳腔和与其同心地围绕腔体定位的环形槽，多个的肋形成在其直径方向的内圆筒部分和外圆柱形部分之间的环形槽中，并且包括平行于引导槽的肋，内圆柱形部分具有与外圆柱形部分的端面齐平或突出超过外圆柱形部分的端面的端面，至少所述肋与所述引导槽平行，每个所述引导槽的端面与所述内圆柱形部分的端面齐平。
