火ダンパーを有するウエザーカバー。 Inside the weather cover 1 attached to the ventilation hole 8, a fire damper 2 for the purpose of closing the lower opening 7 in case of a fire is fixed such that one end having a spring 6 is movable, and the fire damper 2 is made of an elastic material. A metal 4 is used to fix the weather cover 1 to the weather cover 1 by pulling it up with a stopper 3 to open it, and between the stopper 3 and the weather cover 1, a shape memory alloy that remembers the compressed shape 9 of the spring is stretched. If the internal temperature of the weather cover 1 rises due to a fire, the shape memory alloy spring will change to its memorized contracted shape, pull up the stopper 3, and the fire damper 2 will release the spring 6.
A weather cover having a fire damper that closes a lower opening 7 with a force of .
