Abstract
A damper structure for a gear device, which includes a first gear mounted to turn with respect to a shaft in a circumferential direction, a second gear mounted on the shaft to rotate integrally, a stopper rubber mounted on the second gear to face the first gear, and a pressing protrusion at the first gear to face the second gear. The stopper rubber is configured to be elastically deformed by pressing the pressing protrusion in a circumferential direction of the second gear during rotation of the first gear and be restored to the initial shape by separating the pressing protrusion during stop of the first gear. A recess for accumulating lubricating oil in the first gear is formed to face the stopper rubber.
