Abstract
A reduction gear includes an external gear, an internal gear which meshes with the external gear, a first member which synchronizes with a rotation of the external gear, a second member which synchronizes with a rotation of the internal gear, and a main bearing which is disposed between the first member and the second member, in which one of the first member and the second member is connected to a driven member and the other is fixed to an external member, and the first member, the second member, and the main bearing are formed of a material having a larger Young's modulus and larger specific gravity than those of a material constituting the external gear and the internal gear.

A reduction gear comprising:
- an external gear;
- an internal gear which meshes with the external gear;
- a first member which synchronizes with a rotation of the external gear;
- a second member which synchronizes with a rotation of the internal gear;
- and
- a main bearing which is disposed between the first member and the second member,
- wherein one of the first member and the second member is connected to a driven member and the other is fixed to an external member, and
- wherein the first member, the second member, and the main bearing are formed of a material having a larger Young's modulus and larger specific gravity than those of a material constituting the external gear and the internal gear.
A reduction gear comprising:
