A drive apparatus for reversible movements of an actuator (9) is provided with a drive element made from a shape memory alloy with one-way effect. The drive element acts upon a lever (1) rotatable about an axle (2) in opposition to the force of a resetting element, wherein the lever (1) can be used as a coupling member for converting a deformation of the drive element into a movement of the actuator (9). The drive element is a winding (8) with a plurality of turns of a wire (7), wherein the turns are fixed and arranged mechanically parallel between an anchor point (6) and the lever (1) so that the lever (1) is rotatable about the axle (2) by means of a deformation of a turn, and the tractive force acting upon the lever (1) by means of the drive element results from the individual forces of the turns of the winding (8) acting mechanically parallel upon the lever (1). The diameter of the wire (7) is advantageously approximately equal to the standardised diameter of the crystalline grain of the shape memory alloy in the austenitic state.
