As shown in FIG. 9E, contact between the end portion of the rotary core 340 and the intersection region of the rotary disk 355 is caused by the weight of the rotary core, but the magnetic attraction force due to the current I does not work between the two. There is a significant play d1 between the core 340 and the fixed plate 320. On the other hand, when the current I is applied to the core coil as shown in FIG. 9F, a significant force is applied between the end portion of the rotary core 340 and the intersection region of the rotary disk 355 by the magnetic attraction force, thereby driving the rotary core 340.
