ダンパ開閉装置。 A damper is rotatably installed inside the ventilation duct to adjust the cross-sectional area of the air passage by rotation, and a damper is installed outside the ventilation duct to compare the shape at room temperature and the shape when the shape is recovered by thermoelastic martensitic transformation. A shape memory alloy whose shape displacement forms a predetermined angle is provided, one end of the shape memory alloy is fixed to the rotating shaft of the damper, and the other end is regulated to restrict shape displacement when the shape is restored, so that the shape displacement is allowed. A damper opening/closing device for a ventilation duct, characterized in that the damper opening/closing device for a ventilation duct is engaged with a regulating member that causes a predetermined angular displacement direction of one fixed end of the damper to coincide with a damper closing direction.
