<p>A rack guide (150) transmits a preloading force from a spring (36) to a steering rack (14) in a rack and pinion steering gear housing (12). The rack guide (150) is a cylindrical structure having an outer peripheral wall surface (154) with a cylindrical contour complementary to a cylindrical inner surface (14) of the housing (12), and further having an end wall surface (158) with a cylindrical contour complementary to a cylindrical surface (56) of the rack (14). The cylindrical structure (150) has relatively movable parts including circumferentially separate segments (170, 172), each of which defines a respective segmental portion of the outer peripheral wall surface (154). The relatively movable parts of the cylindrical structure (150) further include a flexible web (190) which interconnects and supports an adjacent pair of segments (170, 172) for movement relative to each other. <IMAGE></p> |
