TRAIN WHEEL MEMBER OF CLOCK FOR TRANSMITTING ROTATION

摘要

PROBLEM TO BE SOLVED: To provide a wheel train member in which two gears are easily fixed while matching the phase. SOLUTION: A first gear 710 of this wheel train member for transmitting rotation has a center hole. A guide pin 712 is fixed to the first gear 710. A second gear 720 of the wheel train member for transmitting rotation has a center hole 720a. A position of the guide pin 712 is determined so that an outer circumferential part of the guide pin 712 hits the vicinity of a gear trough 720c of the second gear 720 when the center hole of the first gear 710 and the center hole 720a of the second gear 720 are registered. The first gear 710 and second gear 720 are incorporated in one part. The center hole of the first gear 710 and the center hole 720a of the second gear 720 are then registered. The first gear 710 and second gear 720 rotate integrally.
