Beschreibung
Zusammenfassung:	The invention relates to a drive device for the generation of an oscillating movement for at least one working unit (9) in a small electrical appliance. Said drive device comprises a coil (4), for generation of a magnetic field, which emanates from a first drive component (1) and interacts with a second drive component (2), movably arranged in the small electrical appliance, such as to set the second drive component (2) in an oscillating movement. The first drive component (1) is movably embodied in the small electrical appliance such as to carry out an oscillating movement in counter-phase to the second drive component (2). The drive device comprises a coupling element (17), by means of which a rigid coupling for both drive components (1, 2) in a direction parallel to the movement direction of both components and an elastic coupling between the both drive components (1, 2) in a direction perpendicular thereto can be achieved.
