An electric power steering system includes: an annular elastic member (52) that is made of resin, that is arranged between an inner end face (18e) of a housing (18) and an outer ring (42) of a bearing (40) 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 (18); and a supporting member (51) that restricts axial movement of the cylindrical member within a predetermined range, and that restricts radially inward movement of the elastic member (52). |
