摘要：
The invention relates to a drive device for driving a brush element (5) of an electric toothbrush. Said drive device comprises a first drive component (25) for generating a magnetic field and a second drive component (26) which can be driven in both a translational and rotational manner under the influence of the magnetic field. The drive device according to the invention also comprises a transmission element (4) that can be deflected out of a pre-determined position for the transmission of a translational movement and a rotary movement of the second drive component (26) along a longitudinal axis (3) of the transmission element (4) to the brush element (5). The drive device according to the invention is characterised in that the deflection of the transmission element (4) out of the pre-determined position varies along the longitudinal axis (3) of the transmission element (4).
