ABSTRACT:
A reciprocal linear driving unit and a rolling driving unit are adjacently provided on a common single shaft in axial direction thereof, so that the reciprocal linear driving in the axial direction and the rolling driving around the axis are performed by the single shaft, simultaneously. Permanent magnets constituting the reciprocal linear driving unit and the rolling driving unit are respectively provided on moving object side instead of stator, in other words, they are provided around the axis of the shaft, thereby respective permanent magnets can be miniaturized and light-weighted. Following to this, miniaturization, light-weighting and cost reduction of an actuator and a power toothbrush using the same can be realized.
