<p>An eccentric oscillation-type gear device (1) comprising: eccentric sections (10a, 10b); oscillating gears (14, 16); an outer tube (2) having an internal gear pin (3) that engages with the outer teeth (14a, 16a) of the oscillating gears (14, 16); a carrier (4); and an oil seal cap (30). A closed space (S) housing the oscillating gears (14, 16) is formed by the carrier (4) and the outer tube (2). A penetration hole (4d) and a crank shaft attachment hole (4e) that connect to the closed space (S) are formed in the carrier (4). The oil seal cap (30) is arranged on the penetration hole (4d) and the crank shaft attachment hole (4e), and has strong magnetism so as to be capable of attaching metal powder.</p> |
