ABSTRACT:
An electric toothbrush with a handle and a brush member having a brush head, individual cylindrical bristle holders with tufts of bristles held rotatably in the brush head. They are set into an oscillatory rotating movement by means of a connecting rod executing a reciprocating sliding movement and simultaneously an oscillatory movement about its longitudinal axis, with transverse grooves, disposed therein. In addition, a bristle holder plate in the brush head is held so as to oscillate about a shaft running in the longitudinal direction of the toothbrush. Thus, during the oscillatory movement of the bristle holders the bristle holder plate swivels back and forth in synchronism with the connecting rod.
