摘要：
The transmission (48) according to the invention for an electric toothbrush serves to transmit and convert a rotation movement from an electric motor (58) into a particularly gentle and effective cleaning movement of a cleaning element (40). The ratio of the distance between the longitudinal centre axis of a drive shaft (30) and the longitudinal centre axis of a drive shaft (60) of the transmission (48) and of the distance between the longitudinal centre axis of a shaft (60, 78) driving a cam (72) of the transmission (48) and of the longitudinal centre axis of the cam (72) is at least 10:1.
