In an air duct selector, a supporting member has a grid shape, and is formed with four penetration holes. Since a film member is affixed to two fitting portions which are arranged on two ends of the supporting member, the film member is fixed on the supporting member. The supporting member and the film member are arranged in a duct to move in a vertical direction. When air flow is blown against the inside surface of the film member through the penetration holes 24a.about.24d, the film member is bent to swell against the film member, and presses against a peripheral portion of a cool air bypass opening portion to entirely cover the cool air bypass opening portion.

[ What is claimed is:] [1.] An air duct selector comprising:a duct for containing air flowing in the duct, said duct defining first and second paths therein;an overhanging portion defining first and second coplanar airflow openings therein, said first and second paths respectively connecting to an upstream portion of said duct via said first and second airflow openings;a supporting plate member having a flat major surface and disposed downstream from the air flowing in said upstream portion of said duct proximate to said first and second airflow openings and being slidable in a plane parallel to a plane containing said first and second openings, said flat major surface of said supporting plate member having at least one air penetration hole defined therethrough;flexible film means, disposed on said supporting plate member, for pressing against said overhanging portion responsive to air pressure thereagainst from air flow into said at least one air penetration hole, to form a seal with said overhanging portion around at least one of said first and second airflow openings, thereby preventing air from flowing from said upstream portion through said at least one of said first and second openings.
