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: An electric power steering system includes: an annular elastic member that is made of resin, that is arranged between an inner end face of a housing and an outer ring of a bearing that supports a cylindrical member that rotates coaxially with a rack shaft, and that supports the cylindrical member such that the cylindrical member is movable in the axial direction with respect to the housing; and a supporting member that restricts axial movement of the cylindrical member within a predetermined range, and that restricts radially inward movement of the elastic member.
