装置。 A damper device having a means for biasing a damper blade in a closing direction, a blade stopper, and an opening/closing handle, the damper device is provided with a closing actuation mechanism insertion hole protruding from the damper wall, and a tip of the closing actuation mechanism is inserted through the closing actuation mechanism insertion hole. an actuating lever support member whose portion is disposed outside the rotation area of the damper blade and whose base end is fixed to the damper outer wall; A closing actuation mechanism comprising a lever and a shape memory alloy that contracts depending on a set temperature, which is provided between the tip of the actuation lever and the tip of the actuation lever support member, and is capable of being freely attached to and detached from the outer wall of the damper. The opening/closing handle is locked between the actuation lever support member and the base end of the actuation lever in an open state, and the damper blade is held in an open state and is engaged by contraction of the shape memory alloy. A fire prevention damper device comprising a locking member configured to be released from the lock and having a predetermined arm length to reduce the required actuation force of the shape memory alloy.
