<P>PROBLEM TO BE SOLVED: To provide a vehicular air-conditioner enabling reduced-pressure-proof design of a component in a refrigerating cycle apparatus. Ž<P>SOLUTION: The vehicular air-conditioner has a steam compression type refrigerating cycle apparatus 1 including a refrigerant circuit 11 with a refrigerant flowing therein. An in-cabin side flow passage 11b of the refrigerant circuit is arranged in a cabin-side space 21, a driving device side flow passage 11a of the refrigerant circuit is arranged in an installation space 20 of the driving device for driving a vehicle, and the cabin is air-conditioned by using the refrigerant flowing in the refrigerant circuit 11. The vehicular air-conditioner is a means that can open/close passages in the refrigerant circuit 11 and has a solenoid valve 9 and a non-return valve 10 as refrigerant flow regulating means for regulating the flow of the refrigerant in the in-cabin side flow passage 11b of the refrigerant circuit. Further, the solenoid valve 9 is controlled so as to open the flow passage of the refrigerant circuit 11 when the driving device is in an operating state, and the air-conditioning operation is stopped.
