PROBLEM TO BE SOLVED: To provide an air conditioning device for a vehicle capable of preventing a concentration of refrigerant from being increased in a cabin. SOLUTION: The air conditioning device has a detection means capable of detecting leakage of a combustible refrigerant at the downstream of an evaporator or in the cabin. When the leakage of the combustible refrigerant is detected by the detection means, a control means of the air conditioning device drives a motor for switching between inside air and outside air, and forcibly switches an air introduction mode to an outside air introduction mode. The outside air introduction mode is the mode which performs the outside air introduction from the outside air, and at the same time, opens the exhaust port for preventing the increase of the pressure in the cabin. The control means forcibly operates a blower 4, and switches the blow-out port feeding the air into the cabin into the blow-out port in the direction of the occupant's upper body or the blow-out port for a window or combination of both blow-out ports.
