<Problems to be Solved by the Invention> However, the air supply damper device disclosed in Japanese Utility Model Publication No. 60-5227 requires a larger space for opening and closing because the blade body is a single blade. In addition, since the whole becomes large, the above-mentioned Jitsuko Sho 59-1675.
The air supply damper device of Japanese Patent Laid-Open No. 1 is unsatisfactory in that the ventilation area becomes narrow as a result of the opening / closing structure, and sufficient ventilation performance cannot be obtained, and there is room for improvement.

Further, according to the technique of rotating / opening / closing the wing body in a butterfly shape using a gear group as disclosed in Japanese Utility Model Publication No. 45-18875, it is possible to avoid an increase in the size of the device, and also, Japanese Utility Model Publication No. 59-16751. Although higher air permeability can be obtained compared to the technology of the publication, the reduction of air flow due to the resistance of each of these members is unavoidable because the gear group and the members that transmit the driving force to it are in the air passage. There is a drawback in that there are many failure factors because dust and the like are easily attached to each member in the ventilation passage.

<Effect of the Invention> In the air supply damper device according to the present invention, as described above, a so-called butterfly type composed of a pair of blades is used as the “damper body”, and each blade body has a corresponding shaft body. Since it is rotated and opened and closed by rotating, the space required for opening and closing the wing body is half that of a single-blade type, and all the drive system members including the gear group are outside the ventilation passage. Since it can be provided in the air conditioner, it is possible to obtain a ventilation area of nearly 100%, and it is possible to effectively prevent dust and the like from adhering to each member of the drive system, which causes a failure.
