Timepiece with a device for suppressing hand motion irregularity |
摘要 |
To provide a hand motion irregularity suppressed timepiece whose assembling ability has been improved. As to a spring (107) having a flat portion (112) and a bent portion (111), the flat portion is disposed between a second chronograph wheel (102) and a center wheel (104), and the bent portion (111) is sandwiched and supported under a pressurized state by a train wheel bridge (101) and a bottom plate (106). By this, the spring portion prevents a hand motion irregularity of the second chronograph wheel (102) by the fact that the second chronograph wheel (102) is pressure-contacted with the train wheel bridge (101). Further, by forming a gap between the second chronograph wheel (102) and the center wheel (104), an accompanying rotation between the second chronograph wheel (102) and the center wheel (104) is prevented. <IMAGE> |
