Title: Eccentricity clock having spindle
Inventor: HIRATANI EIICHI
IPC: G04B5/02
Filed: 2001-04-13
Abstract: PROBLEM TO BE SOLVED: To provide an eccentricity clock having a spindle where clocking error due to shock can be reduced. SOLUTION: Buffer materials 72-74 made of an elastic body are provided between a rotary spindle 31 for automatically winding up a spring and a movement 60, thus absorbing vibration that is generated when a rotary spindle 31 deviates from the rotary region of the rotary spindle 31 and collides with the movement 60 using the buffer materials 72 and 74. As a result, even if the rotary spindle 31 tries to be vibrated in an axial direction by shock applied to the clock, the rotary spindle 31 comes into contact with the buffer materials 72-74, hence the vibration of the rotary spindle 31 is attenuated rapidly, thus nearly preventing the clock from advancing due to vibration and reducing clocking error due to shock even if the vibration reaches a speed regulation means such as a generator and a balance.
