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.
