摘要：
PROBLEM TO BE SOLVED: To provide a shock-resistant device for a generator equipped with a vibrating plumb hob. SOLUTION: This shock-resistant device comprises a casket 2 which is inserted into an interlock between the rotor 11 of a generator 1 and a vibrating plumb hob 3. The casket comprises a spiral coiled spring 4 and a slide strip 6. The slide strip 6 is wound in the same direction as the spiral coiled spring over one turn of the spring without being coupled mechanically to the spring, and it forms a protective envelope in the release position at a time when a shock is applied. This shock-resistant device can be applied to the generator of a wrist watch.
