Provided is a heat pump-type vehicle air conditioning device with which comfort can be improved when switching to heating by an auxiliary heating device alone. The present invention is provided with a heating medium circulation circuit 23 for heating air to be supplied into the vehicle interior from an air flow passage 3. In a heating mode, when transitioning to heating of the vehicle interior by only the heating medium circulation circuit 23, a controller executes a transition time control so as to increase the heating capacity of the heating medium circulation circuit 23 before stopping a compressor 2 and to decrease the heating capacity of a heat radiator 4 in accordance with the increase in the heating capacity of the heating medium circulation circuit 23.
