Provided are a rack guide capable of stably supporting a rack while preventing the generation of knocking sound, and a gear mechanism using the rack guide. The rack guide (30) is provided with: a cylindrical synthetic resin rack guide body (31) having a guide surface (310) formed on the distal end surface thereof, the guide surface (310) sliding with respect to the rear surface (22) of the rack (20); synthetic resin support parts (32a, 32b) that protrude from the outer peripheral surface (311) of the rack guide body (31) and are movable in the radial direction of the rack guide body (31); and force applying parts (33a, 33b) which are provided to each of the support parts (32a, 32b), extend in the circumferential direction from both sides of the support parts (32a, 32b) in the circumferential direction of the rack guide main body (31), are connected to the rack guide main body (31), and apply force to the support parts (32a, 32b) toward the outside in the radial direction of the rack guide main body (31) and are made of synthetic resin.

    提供能防止敲打声的产生并能稳定地支撑齿条的齿条引导件以及使用它的齿轮机构。齿条引导件(30)具备:圆柱状的合成树脂制的齿条引导件主体(31),其在末端面形成有相对于齿条(20)的背面(22)滑动的引导面(310);合成树脂制的支撑部(32a、32b),其从齿条引导件主体(31)的外周面(311)突出,并且能在齿条引导件主体(31)的径向移动;以及合成树脂制的施力部(33a、33b),其设于每个支撑部(32a、32b),在齿条引导件主体(31)的周向上从支撑部(32a、32b)的两侧沿周向延伸而与齿条引导件主体(31)连接,朝齿条引导件主体(31)的径向外方对支撑部(32a、32b)施力。
