Abstract
The invention is directed to an electric toothbrush having a brush section and a drive shaft received in the brush section. The brush section includes a first bristle supporting structure operatively coupled to the shaft for motion about an axis essentially perpendicular to a longitudinal axis of the shaft, and a second bristle supporting structure operatively coupled to the shaft for substantially transverse oscillating motion of the entire second bristle supporting structure relative to the longitudinal axis of the shaft. The first bristle supporting structure is generally cylindrically shaped and carries a plurality of bristle clusters.
