Patent number: 8651992Abstract: Through holes are formed in a revolving gear which revolves while being engaged with a ring gear, and penetration pins are inserted in the through holes. An elastic member having a circular ring shape, which is formed so that an inner diameter thereof can move with respect to an outer diameter thereof, is mounted to either an inner circumferential surface of the through hole or an outer circumferential surface of the penetration pin. Thus, the through hole and the penetration pin do not interfere with each other, and thus, it is possible to set a small clearance between the through hole and the penetration pin to such a degree, while preventing a speed reducer from being in a locked state due to interference. As a result, it is possible to suppress a backlash between the through hole and the penetration pin.Type: GrantFiled: March 20, 2012Date of Patent: February 18, 2014Assignee: Seiko Epson CorporationInventor: Yuya Kataoka
