気扇カバー。 The ventilation fan cover main body 1 has left and right side plates 2, and a plate 3 whose upper part is made of a shape memory alloy and is attached to the cover main body 1, which functions as a cover and a fire damper. When used after being opened to the shape 5 at room temperature, the shape memory alloy returns to the memorized shape from 5 to 6 when the temperature rises when a fire occurs, and the magnet 4 attracts the closed plate 3. Ventilation fan cover that acts as a fire damper and closes completely.
