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: The steering apparatus includes a first seal member and a second seal member. The first seal member is fixed to one of an outer peripheral surface of a rack shaft and an inner peripheral surface of a housing. The first seal member slidably contacts with a cylindrical surface which is centered on the axis and is provided on the other of the outer peripheral surface of the rack shaft and the inner peripheral surface of the housing. The second seal member is fixed to the other of the outer peripheral surface and the inner peripheral surface. The second seal member slidably contacts with a cylindrical surface which is centered on the axis and is provided on the one of the outer peripheral surface of the rack shaft and the inner peripheral surface of the housing.
