<p><P>PROBLEM TO BE SOLVED: To thin a device for correcting a time display mechanism. <P>SOLUTION: This correction device of the present invention has internal teeth 16 with a pitch P. The correction device has a pinion 26 and a correction gear 38. The pinion has a gear 30 with a pitch p. The correction gear is mounted between the pinion and a display member. The correction gear has the first gear 40 formed of teeth 42. The first gear has the pitch P, a head part diameter D and a leg part diameter d1. A tip of the first gear forms the second gear 46. The second gear 46 is coplanar and concentric. The pitch p of the second gear 46 is smaller than the pitch P of the first gear 40, the head part diameter D of the second gear is equal to the head part diameter D of the first gear, and a leg part diameter d2 of the second gear is larger than the leg part diameter d1 of the first gear. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
