ド等におけるダンパー装置。 It consists of an exhaust duct installed in communication with an exhaust device such as a range hood, a damper body disposed within the exhaust duct, and a contracting body made of a shape memory alloy attached to the damper body. The damper body rotatably supports two damper pieces, and each damper piece is biased in the direction of closing the damper flow path by the biasing force of a spring, and the contracting body has a heating effect. A damper device for a range hood or the like, characterized in that the damper device is configured to contract against the biasing force of the spring to open the damper flow path.
