Claims

[Scope of claims for utility model registration] 1. A blade rotating shaft of a damper blade protruding above the duct frame,
an interlocking rotation shaft that is connected and fixed on the blade rotation shaft and rotates in conjunction with the blade rotation shaft; and a piston interlock rotation that is disposed in parallel with the interlock rotation shaft and is loosely fitted onto the blade rotation shaft and rotates when the piston is actuated by gas pressure. a shaft, a spring having one end fixed to the piston interlocking rotation shaft and the other end fixed to the interlocking rotation shaft; and with the spring energized and spring return force accumulated, the interlocking rotation shaft is moved to the piston interlocking rotation shaft. and a temperature at which the engaging pin is disengaged when the temperature fuse is activated due to a temperature rise in the duct, and the engagement pin is biased to release the engagement between the interlocking rotation shaft and the piston interlocking rotation shaft. A fire prevention damper opening/closing device characterized by being provided with a fuse interlocking arm.
