Claims

[Scope of utility model registration request]

A main gear integral with a gear shaft, an auxiliary gear having the same shape as the main gear or a shape similar to the main gear and fitted on the gear shaft so as to be relatively rotatable, and an auxiliary gear interposed in the main gear and the auxiliary gear. The meshing noise prevention gear is composed of a preload spring that rotates the auxiliary gear in one direction with respect to the main gear, and the preload spring has a ring shape surrounding the gear shaft, and a part of the circumferential direction of the preload spring is shaped like a ring surrounding the gear shaft. One end of the preload spring is provided with a main spring locking hole that can be locked with the locking hole of the main gear through a main locking pin, and the other end of the preload spring is provided with a main spring locking hole that can be locked with a main locking pin. An auxiliary spring engagement hole that can be engaged with the engagement hole of the auxiliary gear via an engagement pin is provided adjacent to the hole and the tool locking hole, and the main gear is provided with a spring that is movable in the circumferential direction with respect to the engagement pin. A meshing noise prevention gear characterized by being provided with a main engagement hole that can be freely fitted.
