Abstract
With a rack-and-pinion mechanism, an impact force is absorbed and reduction in assembling performance is suppressed. An annular fitting groove (51) that extends in the circumferential direction of a rack guide (41) is formed in an outer peripheral face (41a) of the rack guide (41), and an O-ring (52) is fitted in the fitting groove (51) in a state in which the axial movement of the O-ring (52) is restricted. A communication groove (61) that provides communication between an internal space (55), defined by the fitting groove (51) and the O-ring (52), and the outside of the rack guide (41) is formed in the rack guide (41).
