| 摘要 | PURPOSE:To enable the manufacture easily and at a low cost with a strong resistance to vibration and impact by use of a clutch mechanism utilizing a spring force of physical property. CONSTITUTION:As a rotor 1 turns, a rotation torque is applied to an intermediate wheel 2 and then to a minute wheel 3, an intermediate wheel 8, a minute wheel 6 and a hour wheel from a back wheel of date to form a wheel train mechanism. When the pointor turning torque for the time correction exceeds a fixed value, a gear of the center wheel 6 deflects and is disengaged from the intermediate wheel 8 to make the minute wheel free to rotate. Thus, the time correction can be performed. | ||||||
