Abstract
The invention is directed to a brush section (1) for an electric toothbrush which includes a mounting tube (2) in which a shaft (7) rotatably mounted about a longitudinal axis (3) and driveable in an oscillatory or rotary fashion is received. Further, the brush section (1) includes a bristle carrier (11) which is pivotally mounted on an angled end (19) of the shaft (7) configured as crankshaft and which, in operation of the electric toothbrush, is set in a rotary motion (26) about the transverse axis (14) by a pin (23). The angle (20) formed by the longitudinal axis (3) and the angled end (19) of the shaft (7) serves the added function of causing the bristle carrier (11) to perform a pivotal motion (27) about an axis (28).
