A sliding door (1) which is movable back and forth in the sliding direction by means of a fixed drive motor unit possessing a drive pinion (2) which meshes in the toothing of a toothed rack (3) attached to the door leaf or the bottom beam of the door (1); in the interest of making the toothed rack cheap to manufacture and adaptable to the sliding length of the door, also in order to permit easy replacement of sections of the rack which are particularly exposed to wear, the said rack is made up of a series of toothed segments (5, 5', 5") fitted in sequence in a mounting rail (4) attached to and running in the sliding direction of the door leaf; these segments are produced as finished castings or injection moulded parts and they are fixed in relation to each other so that the correct sequence of tooth pitch is maintained.
