A driving mechanism for slat curtains, the slats of which can be displaced in a direction transverse to their longitudinal axis and rotated about the longitudinal axis of the slats, comprising a gearing having one drive end and two power take-offs of different torques for connection to a transport rod (7) effecting the longitudinal displacement of the slats and a tilt rod (6) effecting their rotary movement, the rotary movement of the power take-off coacting with the tilt rod being limited by stops arranged on coaxial parts rotatably seated for being driven by the power take-off associated with the tilt rod, coacting stops being arranged along the same circular paths, is characterized in that the rotatably seated parts take the form of at least two disks (30, 32) of substantially identical diameter arranged in parallel to each other and that the one outermost disk is coupled to the power take-off associated with the tilt rod (6), that the rotary movement of the other outermost disk (32) is limited by a stop which is fixed in position relative to the housing of the driving mechanism, and that every two directly neighboring disks carry the coacting stops (37, 38) arranged along the same circular paths. Thus, a simple and space-saving arrangement is achieved.
