Claims

[Scope of utility model registration request]

One gear of the gears that mesh with each other is formed by laminating a metal gear body and a resin gear body, and supporting these gear bodies so that they can rotate about their respective axes, and furthermore, the laminated gear body is The gear teeth of the resin gear body are connected to the metal gear body so that the gear teeth of the resin gear body mesh with the other gear in a natural state with priority over the gear teeth of the metal gear body. A low-noise gear device characterized in that the gear teeth are connected via a damper in a laminated state that protrudes in the rotational direction from the gear teeth.
