Abstract
A motor-driven toothbrush includes a housing adapted to be gripped by the user and containing an electrical rotary motor, and a toothbrush coupled to the rotary motor by an eccentric coupling such that rotation of the motor causes the toothbrush to oscillate. A sleeve threadedly received in the end of the housing through which the toothbrush handle passes defines a pivot point for the oscillations of the handle, and is adjustable with respect to the housing so as to permit varying the location of the pivot point, and thereby the type of oscillations produced by the rotary motor.
