Since it is attracted by the S-pole permanent magnet 9, it is held at that position. Next, when the coil 3 is energized so that the rotary plate 8 is oriented in the south pole direction, a repulsive force is generated between the rotary plate 8 and the permanent magnet 9.
At the same time as rotating to the permanent magnet 5 side of the pole, it is attracted by the permanent magnet 5 and stopped at the stop position by the rotary plate stopper 4, and is held at that position.
