Claims

[Scope of utility model registration request]

A protrusion is provided around the inner wall surface of the duct, both ends of a damper blade having a shape such that the peripheral edge is moored to the protrusion are pivoted through the duct wall, and a double shaft mechanism with the damper blade rotation shaft is provided. The central shaft of the damper blade is pivoted through the duct in the same manner as above, and a locking pin is provided protruding from the outer periphery of the central shaft, while a required interval is provided between the rotating shaft of the damper blade that penetrates the outer wall of the duct and the outer periphery of the central shaft. A main shaft plate portion and a motor interlocking plate portion are respectively attached, and a spring member is interposed between the main shaft plate portion and the motor interlocking plate portion, so that the locking pin is integrally attached to the damper blade against the biasing force of the spring member. furthermore, an actuating lever mounting base is mounted on the damper blade, straddling the central axis, having an opening through which the locking pin rotates in a loose fit manner, and having an actuating lever support portion formed therein; a base of the actuation lever is pivotally mounted to the base of the actuation lever support in a manner opposite to the actuation lever support;
The proximal end of the operating lever and the outer edge of the operating lever support part are constantly closed off by a locking piece formed on the outer periphery of the operating lever by the biasing force of a tension spring member, and further Set temperature 65 to 75℃ between the tip and the tip of the above operating lever.
A damper device characterized in that a shape memory alloy member is connected to the biasing force of the tension spring member to contract into a set shape.
