Patent number: 10436443Abstract: A closing member includes an annular portion and a flange portion. The annular portion is provided with a through hole and is in contact with an outer circumferential surface of an exhaust tube in at least a part of the through hole. The flange portion extends from an outer circumferential surface of the annular portion toward an outer side and is larger in outer diameter than an exhaust pipe. The flange portion contacts a tip end portion of the exhaust pipe on outside of a building so as to close a gap between the exhaust pipe and the exhaust tube. The flange portion is formed to protrude toward an outer side such that an entire circumference of the flange portion extends beyond an outer circumferential surface of the tip end portion of the exhaust pipe.Type: GrantFiled: March 29, 2016Date of Patent: October 8, 2019Assignee: NORITZ CORPORATIONInventor: Masaki Sugatani
