Abstract: A damping stopper is interposed between two members axially displaced relative to each other and is provided with an elastic body which, when the interval between the two members decreases, is axially compressed by the two members and expands radially outward. In the elastic body, a second member suppressing the expansion is located in one axial region and attached to the outer periphery. When axially compressed by the two members, the elastic body expands while receiving resistance by the second member. The expanding elastic body contacts the side wall of one of the two members.

Abstract: A steering system includes a rack shaft, a tubular rack housing, and a tubular rack bushing. The rack bushing is interposed between the outer surface of the rack shaft and the inner surface of the rack housing. The rack bushing supports the rack shaft such that the rack shaft is slidable in the axial direction. The rack housing includes an annular groove on its inner surface. The rack bushing includes a collar. a through slit. and first non-through slits. The collar protrudes radially outward from substantially the entire circumference of the rack bushing. The collar is fitted into the annular groove. The through slit passes through the rack bushing in the axial direction. Each first non-through slit extends in the axial direction such that the first non-through slit passes through a portion of the rack bushing whose axial position corresponds to the axial position of the collar.

Abstract: Two flat surface portions are provided on portions of a rack shaft away from rack teeth and a back surface in the circumferential direction. The two flat surface portions are parallel to each other. A rotation stopping member has a case and a low-friction member. The hollow portion provided inside the case includes two flat surface portions that face each other in a direction Y and extend in parallel with each other, and two flat surface portions that face each other in a direction Z and extend orthogonally to the flat surface portions. A slight clearance is provided between the outer surface of the rack shaft and the inner surface of the rotation stopping member (low-friction member). The rotation stopping member is disposed on the outer periphery of the rack shaft. The outer periphery of the rotation stopping member is fixed to the inner periphery of a rack housing.

Abstract: A rack guide unit includes a closure member, a rack guide, and an urging unit. The closure member is secured to an external opening end of an accommodation portion of a housing. The rack guide is accommodated in the accommodation portion so as to be movable in an advancing/withdrawing direction and supports the rack shaft so that the rack shaft is slidable in an axial direction. The urging unit is arranged between the closure member and the rack guide. The urging unit includes a stack of a plurality of coned disc springs urging the rack guide toward the rack shaft and arranged in an identical orientation, and an auxiliary coned disc spring that serves as a holding member holding the stack.
