Abstract

PURPOSE:To perform minute setting and hour setting with one alarm rotary shaft by providing a minute-unlocking wheel and an hour-unlocking wheel with ratchets differing in engagement direction from each other each in one body, and by providing a feed wheel which has arms engaging with those ratchets. CONSTITUTION:A minute-unlocking wheel 17 and an hour-unlocking wheel 18 have ratchets 30 and 31, which each have 24 teeth on the reverse surface, in one body respectively. The teeth of those ratchets 30 and 31 are formed in the opposite directions. When a feed wheel 38 is turned in one direction by an alarm rotary shaft 36, the arms 40a-40d of the feed wheel 38 engage with the ratchet 30 or 31, and the minute-unlocking wheel 17 or hour-unlocking wheel 18 is rotated. When the feed wheel 38 is reversed, the other wheel 17 or 18 is rotated.
