<p>A gear coupling includes an inner cylinder 18a, an inner cylinder 18b, an outer cylinder 13a, an outer cylinder 13b, a closing plate 25a interposed between the inner cylinder 18a and the inner cylinder 18b and closing an inner end face 12 of the outer cylinder 13a, and a closing plate 25b interposed between the inner cylinder 18a and the inner cylinder 18b and closing the inner end face 12 of the outer cylinder 13b. In the closing plate 25a, one or a plurality of through-holes 21 communicating with a device outer side of the closing plate 25a from a grease chamber 24a surrounded by the inner cylinder 18a, the outer cylinder 13a, and the closing plate 25a are formed. In the closing plate 25b, one or a plurality of through-holes 21 communicating with a device outer side of the closing plate 25b from a grease chamber 24b surrounded by the inner cylinder 18b, the outer cylinder 13b, and the closing plate 25b are formed. Plugging members 20 closing the through-holes 21 are fitted to the through-holes 21.</p> |
