る請求項(2)記載の給気ダンパ装置。[Claims for Utility Model Registration] (1) A pair of semicircular damper blades is pivotally supported on a hinge shaft extending inside a cylinder, and the damper blades are automatically opened in response to the reduced pressure inside the room. An air supply damper device that is normally biased in the closing direction by a spring with a weak biasing force. (2) A claim characterized in that the damper blade is provided with a locking means that can freely lock and release the pair of damper blades.
(1) The supply air damper device described. (3) The locking means includes a rotating body that can be rotated by an operating means that can be operated from the outside, and a rotating body that is connected to the rotating body and faces the wing part of each damper blade according to the rotation of the rotating body.・Claim (2) characterized in that the device is equipped with a lock lever that can freely come into contact with the lock lever.
) The supply air damper device described in ). (4) The locking means includes a locking arm having a pair of abutting portions, a spring that urges the locking arm toward the damper blade, and an operating means that operates the locking arm from the outside. By being in a state where they intersect with each other, each of the abutting parts presses against the wing part of each damper blade, and when it is unlocked, each of the abutting parts is in a state of being parallel to the hinge axis, so that each of the abutting parts presses against the wing part of each damper blade. 3. The air supply damper device according to claim 2, wherein the damper device is configured so as not to come into contact with the wing portion of the blade.
