装置。[Scope of Claim for Utility Model Registration] An outside air inlet that is opened in the direction in which outside air dynamic pressure is applied during driving and introduces outside air, an air box that receives the introduced outside air, and an air box that sends the outside air introduced from the air box to a blower unit. A vehicle air conditioner comprising an intake duct and an inside/outside air switching valve that opens an inside air inlet in the middle of the intake duct and switches between outside air and inside air by opening and closing the inside air inlet. A movable flap that changes the flow path cross-sectional area of the introduced outside air sent into the blower unit is provided at a position upstream of the switching valve, and the movable flap has a movable flap that changes the flow path cross-sectional area of the introduced outside air that is sent into the blower unit. 1. A vehicle air conditioner comprising flap control means for controlling a cross-sectional area of a flow path in a direction to narrow it when the air conditioner is in use.
