The transmission according to the invention for an electric toothbrush serves for the transmission and reforming of a rotational movement provided by an electric motor into a particularly careful and effective cleaning movement of a cleaning element. The ratio of the distance between the longitudinal mid-axis of an output shaft and the longitudinal mid-axis of a drive shaft of the transmission and of the distance between the longitudinal mid-axis of a shaft driving a cam of the transmission and the longitudinal mid-axis of the cam amounts to at least 10:1.
