PROBLEM TO BE SOLVED: To provide an air conditioning device for a vehicle which can effectively perform storage of cold by effectively utilizing braking force of a vehicle, secure cooling capability in an idling stop thereby, and reduce air conditioning power consumption in idling without newly adding a cooling radiator exchanging heat between a cold storage medium and air conditioned wind. SOLUTION: The air conditioning device for the vehicle has a cooler, a refrigerant circulation route equipped with a compressor, a heating device, a deceleration determination means of the vehicle, a shut-off mechanism which can shut off flow of cooling water at both sides or one side of an inlet port side and an outlet port side of the heater in a circulation route of engine cooling water entering/leaving the heater. When it is determined or detected that the vehicle is in deceleration state with the deceleration determination means, the shut-off mechanism is shut off and storage of cold is performed by passing the air after passing through the cooler to the heater.
