An antibacklash rack and pinion assembly includes longitudinally movable first and second rack members which have gear teeth thereon which mesh with the gear teeth of the pinion gear. A spring exerts a force in the same longitudinal direction of the movement of the rack members and against one of the rack members so that that rack member moves longitudinally relative to the other rack member and the teeth of that rack member are offset from the teeth of the other rack member. Thereby, opposite sides of at least one tooth of the pinion gear at all times are simultaneously positioned between and held in engagement with at least one tooth on each of the rack members to prevent backlash on movement of the teeth.
