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