The permanent magnets are rotatably installed in the through holes of the frame on an axis parallel to a center axis of the frame. The coils are wound by using as a core a portion between a predetermined pair of through holes adjacent to each other among the through holes of the frame. The driven gears are fixed to the permanent magnets and rotate together with the permanent magnets. The driving gears are in contact with the corresponding driven gears.
