PROBLEM TO BE SOLVED: To positively drive the vibration of a flat vibration motor without generating any vibrating noise. SOLUTION: A bearing part 16 for rotatably supporting the lower edge part of a shaft 15 of an eccentric rotor 14 of a flat vibration motor 10 is provided on the upper surface of a recess 6a of a rear lid 6 that is mounted to the lower surface of a watch case 1, and the flat vibration motor 10 is provided in one piece with the rear lid 6 by supporting the lower edge part of the shaft 15 of the flat rotor 14 by the bearing part 16. As a result, the vibration of the flat vibration motor 10 can be positively transferred to the rear lid 6, so that the vibration of the flat vibration motor 10 does not differ from that of the rear lid 6 greatly, thus preventing a vibrating noise from being generated and positively transferring the vibration of the flat vibration motor 10. |
