Claims

[Scope of utility model registration request]

A gear consisting of a plurality of engaging recesses arranged evenly in the circumferential direction on one side, and a thin annular base made of an elastic material such as rubber or soft synthetic resin, which corresponds to each engaging recess on one surface of the gear. A buffer ring formed by integrally molding a plurality of engaging protrusions that fit together and having an engaging hole drilled in each of the engaging protrusions, and a metal plate having an axial hole bored at the axial center position on the outer periphery of the ring. 1. A shock mitigation gear mechanism comprising: a bearing plate formed by cutting and arranging a plurality of engaging protrusions that are inserted into and engaged with the engaging hole in one direction.
