Claims

[Scope of claim for utility model registration] A smoke exhaust door rotatably supported by a smoke exhaust port provided in a smoke exhaust duct and biased in the opening direction by a release spring; a semicircular rack gear fixed coaxially with the door rotation axis; a reduction gear supported on the fixed shaft on the duct side and meshed with the rack gear; A movable pinion gear, a motor connected to the pinion gear via a reduction gear and driving the rack gear in the opening or closing direction via the reduction gear by forward and reverse rotation of the pinion gear, and a gear meshing with the pinion gear. is formed on a part of the outer periphery and has a rotation center with a radius larger than the gear radius, and when the pinion gear rotates the rack gear in the door opening direction via the reduction gear, the pinion gear is bitten by the -ion gear. A smoke exhaust port opening/closing device comprising: a latch gear which disengages from engagement with a reduction gear at and opens the smoke exhaust door under the bias of the release spring.
