Abstract
An electric toothbrush including a handle, a battery and a motor in the handle, a head, and a tuft carrier movably mounted on the head for oscillation about an axis. The tuft carrier also moves axially as the carrier oscillates. This three-dimensional motion is provided by a plurality of cams and a plurality of cam followers on the head and the tuft carrier. The cam followers engage the cams such that as the tuft carrier oscillates back-and-forth, the cam followers ride up and down over the cams consequently raising and lowering the tuft carrier with respect to the toothbrush head.
