Claims

[Claims for Utility Model Registration] 1. A drive having an eccentric cam that meshes an internal gear and an external gear with different numbers of teeth, which are eccentrically arranged inside and outside the radial direction, and rotationally drives one of these gears. In a gear reducer in which either one of the two gears rotates by an amount corresponding to the difference in the number of teeth between the two gears per one revolution of the shaft, elastic deformation occurs in the meshing portion between the internal gear and the external gear. A gear reducer characterized by interposing a freely movable transmission intermediate member. 2. The gear reduction gear according to claim 1, wherein the transmission intermediate member has outer teeth and inner teeth that mesh with the teeth of the internal gear and the external gear at a meshing portion between the internal gear and the external gear. Machine. 3. The gear reduction gear according to claim 1 or 2, characterized in that a reinforcing material is disposed inside a portion of the intermediate transmission member corresponding to the teeth of both gears. 4. The gear reduction gear according to claim 1, 2 or 3, wherein the internal teeth of the intermediate transmission member mesh with the teeth of the external gear over the entire circumference.
