Abstract
An electric toothbrush has a gear driven by a motor. On the face of the gear is an eccentric pin upon which a sliding member is located. The eccentric pin engages with a socket in a lever which is securely connected to a brush rod. The lever is moved up and down and simultaneously oscillates due to the rotational movement of the eccentric pin so that the brush rod executes a corresponding movement.
