PROBLEM TO BE SOLVED: To improve gas-sealing properties inexpensively and reliably by minimizing the remodeling of an existing damper even without removing the existing flap-type damper and even if the distance between seal surfaces cannot be extended fully. ;SOLUTION: In the remodeling method of the already installed flap-type damper that is connected between an upstream-side duct 12 and a downstream- side duct 20, a movable seal seat 18 is mounted to a surface at the downstream side of an existing damper blade 14 that comes into contact with an existing seal member 13 of an existing damper 11 and can be opened or closed freely, the downstream side duct 20 is cut by a specific length, a connection duct 19 where a newly installed seal member 21 that comes into contact with the movable seal seat 18 is mounted is connected between the downstream side duct 20 that has been cut by a specific length and the exiting damper 11, and the movable seal set 18 and the newly installed seal member 21 are bonded for sealing gas when closing the existing damper blade 14.;COPYRIGHT: (C)2001,JPO
