An air conditioning unit has an air conditioning case, a blower, and a heat exchanger. The air conditioning case is arranged in a vehicle compartment on a rear side with respect to an instrument panel in a traveling direction of a vehicle and forms an air passage delivering air toward a specified area of the vehicle compartment. The blower has at least first and second impellers and a fan case housing the first and second impellers, and ventilates the air in the air conditioning case by drawing and blowing air, by using a rotation of the first and second impellers, through first and second suction ports formed in the fan case. The heat exchanger is arranged in the air conditioning case on an upstream side of the blower in an airflow direction and exchanges heat of the air. The blower draws air from the heat exchanger and blows the air to the specified area of the vehicle compartment. The fan case has a portion in which at least the first and second suction ports are formed, and the portion is arranged inside of the air conditioning case. |
