摘要： In a rolling driving actuator used as a drive source of a power toothbrush, permanent magnets are formed flat plate shape, and constituting a moving object by being attached to grooves formed on an outer peripheral face of a yoke which is press-fitted to and fixed on a shaft. On the other hand, a tubular shaped stator, which is constituted by a coil wound around a bobbin and stationary yokes provided on both side of the bobbin in axial direction of the shaft, is provided to face an outer face of the permanent magnet or an outer face of the yoke of the moving object with a predetermined clearance so that a center axis thereof becomes coaxial with the center axis of the shaft. By supplying an alternating current to the coil, the moving object is driven in rolling driving around the axis of the shaft.

摘要： 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.

摘要： An improved linear oscillating actuator is capable of minimizing the undesired vibrations while moving first and second oscillators in parallel paths. The first and second oscillators carry first and second drive elements respectively for driving connection to individual reciprocating loads. The first and second drive elements project upwardly respectively from the first and second oscillators such that the first drive element is disposed immediately upwardly of the second oscillator and the second drive elements is disposed immediately upwardly of the first oscillator. With this reverse arrangement of the first and second drive elements relative to the first and second oscillators, the individual oscillating systems each including the oscillator, the drive element and the corresponding reciprocating load can have its mass center disposed in close proximity to a mass center of the actuator, thereby enabling to reduce undesired vibrations which would otherwise occur around the mass center of the actuator.

摘要： In a reciprocal linear driving actuator used as a drive source of a power toothbrush, two permanent magnets are formed substantially disc shape or substantially tubular shape, and fitted to and fixed on a shaft directly or via a spacer with a predetermined distance in axial direction of the shaft, so that a moving object is constituted by the shaft and the permanent magnets. On the other hand, a tubular shaped stator, which is constituted by a coil wound around a bobbin and stationary yokes and so on, is provided to face side faces of the permanent magnets of the moving object via a predetermined clearance so that a center axis thereof becomes coaxial with the center axis of the shaft. By supplying alternating current to the coil, the moving object is driven reciprocally and linearly in the axial direction of the shaft.
