The invention relates to a device for operating a sliding door. It is characterised in that the bearing piece (10), with which the sliding door is equipped, comprises at least one so-called additional roller (13) which comprises, in the region of its two flanks, beads for guidance in translational movement, and the free end of the bearer (12) of the operating device is shaped in the manner of an auxiliary rail (14), on which the additional rollers (13) come to bear, and the auxiliary rail (14) has an auxiliary rolling surface which, at least locally, is inclined relative to the longitudinal axis of the fixed rail, in such a way that the passage of the additional roller on this auxiliary rolling surface from at least one of the ends of the ramp as far as its highest part raises the main rolling members by a predetermined height in relation to the main fixed rail. <IMAGE>
