。[Scope of Claim for Utility Model Registration] An air volume control damper 3 is rotatably supported in the ventilation path of the fan 1, and a receiving member 4 is provided at one end of the damper 3 to receive the damper 3 in a state where the ventilation path is minimized. A stepping motor 6 is connected and connected to the rotary shaft 3a of the damper 3, and the rotation of the stepping motor 6 causes the damper 3 to open. A fan airflow control device that can change the opening degree to the maximum opening in stages in approximately proportion to the amount of combustion gas. The receiving member 4 is provided as a receiving pin 4 bent in a crank shape so as to be freely rotatable, and the rotation of the receiving pin 4 displaces the relative position between the damper 3 and the receiving pin 4 to adjust the minimum opening degree. A fan air volume control device according to claim 1 of the utility model registration claim.
