PROBLEM TO BE SOLVED: To sense certainly the concentration of the contaminant substances in the outside air introduced from an outside air intake 40 by a gas sensor 400 even without executing the outside air mode forcedly. SOLUTION: An air-conditioner of a vehicle is equipped with an outside air introducing duct 300, a floor casing body 11, and an inside-outside air changeover door 12 to open and close an outside air introducing hole 11a and an inside air introducing hole 11b selectively. The gas sensor 400 senses the contaminant component contained in the outside air, and the outside air introducing duct 300 is furnished with a hole part 310 to generate communication between the outside and inside. In compliance with the vehicle running dynamic pressure, the outside air introduced from the outside air intake 40 passes around the gas sensor 400 and through the hole part 310, and the flow to exhaust to outside the cabin is generated.
