Gear device

Abstract

A damper structure for a gear device includes a first gear (2) mounted to turn with respect to a shaft (1) in a circumferential direction, a second gear (3) mounted on the shaft (1) to rotate integrally, a stopper rubber (33) mounted on the second gear (3) to face the first gear (2), and a pressing protrusion (24) at the first gear (2) to face the second gear (3). The stopper rubber (33) is configured to be elastically deformed by pressing the pressing protrusion (24) in a circumferential direction of the second gear (3) during rotation of the first gear (2) and be restored to the initial shape by separating the pressing protrusion (24) during stop of the first gear (2). A recess (25) for accumulating lubricating oil in the first gear (2) is formed to face the stopper rubber (33).
