Abstract
A brushing attachment for an electric toothbrush has a neck extending in a longitudinal direction of the brushing attachment, a head at a remote end of the neck, a driveshaft extending in a longitudinal direction of the neck and having a rotation axis extending in the longitudinal direction. There is tuft block mounted to the head for oscillation about a pivot axis extending substantially normally to the rotation axis of the driveshaft. A cam is attached to or formed integrally with the driveshaft and provides a cam surface surrounding the longitudinal axis and being of varied displacement in the longitudinal direction. A cam follower is associated mechanically with the tuft block and bears against the cam surface to effect pivotal oscillation of the tuft block about the pivot axis in use.
