To effectively remove fogging of an internal surface of a window glass 110 of a vehicle.
When a second defog mode is performed, a second fan 30b introduces inside air into a second air passage 10b. A first fan 30a introduces inside air from a first air passage 10a into the second air passage 10b through a communication port 16a. Accordingly, the inside air introduced through an inside air inlet port 11b and the inside air introduced from the air passage 10a through the communication port 16a are subjected to a temperature control performed by an air mix door 70 and blown out of a first defog blow-out opening 12a. Thus, the fogging of the window glass 110 can be effectively removed using the inside air even when the humidity of open air is high and the fogging of the window glass 110 cannot be effectively removed using the open air.
