摘要：
The driving portion 4 is composed of multipolar motor 43. The multipolar motor 43 includes a coil 431 for multipolar motor 43, a stator 432 for multipolar motor 43, for transmitting a magnetic field from coil 431, and a rotor 433 for multipolar motor 43 installed ratably in a stator hole of stator 432. A multipolar magnet is provided on a peripheral part of rotor 433. A plurality of teeth are formed on stator 432 toward rotor 433. Clock hands for displaying time are installed on the rotation axis of rotor 433.
