Abstract
An electric toothbrush has a housing incorporating a motor with a drive shaft rotatable about a longitudinal axis A. A shank extends beyond the housing and is integrally formed with a brush head at its remote end. The shank is pivotably supported intermediate its length in an end wall of the housing. An eccentric cam mounted to the shaft cooperates with a cup on a near end of the shank to form a mechanical coupling. When the shaft rotates both the near end and the brush head moves through a circular path.
