Abstract
The invention relates to an electrically driven toothbrush comprising an electric motor for rotationally driving a drive shaft around a drive axis, a brush shaft having a first free outer end provided with a bristle, conversion means for converting the rotational movement of the drive shaft into a reciprocal rotational movement of the brush shaft around a brush shaft axis according to conversion characteristics, and pivoting means for enabling the pivoting of at least part of the brush shaft around a pivot axis, extending perpendicularly to the longitudinal direction of the drive shaft, from a neutral pivoting position and against the action of forcing means, to a non-neutral position due to forces acting on the bristle, the pivoting of the at least part of the brush shaft around the pivot axis to the non-neutral position causing a change in the conversion characteristics.
