Abstract
A linear motion guide unit is disclosed in which a rack-and-pinion arrangement is interposed between paired guide rails to keep a cage retaining more than one rolling element therein against falling off from the guide rails. In the linear motion guide unit, the cage arranged between confronting raceway grooves of the guide rails hold therein a pinion, which comes in mating with a rack lying in the raceway grooves. The cage is made therein with an aperture in which a thick portion of a pinion holder fits to secure the pinion holder to the cage. The pinion is comprised of a disc having teeth that come in mating with the rack, and a shaft serving as an axis about which the disc rotates. The pinion is held in the pinion holder, with the shaft being carried for rotation in pinion chamber in the pinion holder.
