Claims

[Scope of utility model registration request]

A damper casing connected between the ducts, a rotating shaft rotatably supported inside the damper casing, a blade attached to the rotating shaft to adjust the air volume in the duct, and a rotating shaft. In the damper, the driving means includes a motor and an output shaft that rotates the rotation shaft by driving the motor. , a first cam switch that stops the motor at a fully closed position or a fully open position of the blade, and a second cam switch that stops the motor at an arbitrary maximum or minimum opening position of the blade are attached to the output shaft; A damper maximum/minimum opening adjustment mechanism featuring:
