するように構成したものである。 In order to achieve the above object, the present invention has a permanent magnet that rotates around a rotating shaft attached to a fixed part, a field coil and a ring-shaped yoke are each fixed to the fixed part on the outside of the permanent magnet, and the permanent magnet is fixed to the fixed part. An output lever is attached to the magnet, a magnetic path cutting section is provided in a part of the ring-shaped yoke, and the position of the magnetic path cutting section and the center of the field coil is shifted, so that the magnetic path cutting section is connected to the field coil. When the magnetic coil is not energized, the magnetic poles of the permanent magnet face each other at a magnetic neutral point, and when the field coil is energized, the permanent magnet moves beyond the center of the field coil from the magnetic neutral point where its magnetic poles face each other. When the permanent magnet rotates by a predetermined angle and the field coil is cut off, its magnetic pole rotates back to the magnetic neutral point due to the return force to the magnetic neutral point, and the field coil is turned on and off. By doing so, the output lever is configured to be driven reciprocatingly around the rotating shaft.
