Abstract: A rack guide mechanism includes: a rack guide that presses a rack shaft against a pinion shaft; a housing that movably accommodates the rack guide; an elastic member that biases the rack guide toward the rack shaft; and a gas chamber formation member that is disposed in parallel with the elastic member in a moving direction of the rack guide, and that has a gas chamber therein, and can be contracted in the moving direction, in which when the rack guide moves against the elastic member, the rack guide compresses the gas chamber formation member while compressing gas in the gas chamber.
