Abstract
A toothbrush drive includes a first drive component for generating a magnetic field and a second drive component driven in both a translational and rotational manner under the influence of the magnetic field. A transmission element is deflected out of a predetermined position for transmission of both translational and rotary movement of the second drive component. The deflection of the transmission element varies along its longitudinal axis. A transmission element can be deflected out of a predefined position for transmission of a translatory movement and a rotational movement of the second drive component to the brush element along a longitudinal axis of the transmission element. The deflection of the transmission element out of the predefined position is varied along the longitudinal axis of the transmission element.
