装置。[Scope of Claim for Utility Model Registration] (1) A pinion gear provided on a moving body is engaged with a rack gear disposed along a running path, and this pinion gear is activated by a motor provided on the moving body in response to a position command. In a drive device for a movable body that moves a movable body to a commanded position on a traveling path by driving, a following body capable of traveling along the traveling path is connected to the movable body via a spring, and the following body has a A pinion gear that easily engages with the pinion gear and a motor that drives the pinion gear are installed, and a length necessary for the spring to generate a predetermined force with respect to the commanded position of the moving body with respect to the follower is provided. A backlash prevention device for a moving body, comprising a follower position control means for controlling the position by giving a position command separated by a distance to extend or shorten the position. (2) The backlash prevention device for a moving body according to claim 1, wherein the position control of the moving body is performed by feedback control based on position detection, and the position control of the follower is performed by open loop control.
