Here, a layout in which the indoor air conditioning unit is arranged on the front side of the vehicle rather than the vehicle side strength member is usually adopted because of the arrangement space inside the instrument panel. Further, in this arrangement layout, the vehicle side requires a form in which the upper surface portion of the inside / outside air switching box is arranged further above the vehicle-side strength member so as to expand the occupant's foot space in the vehicle compartment.

In this case, the screw fastening portion for assembling the inside / outside air switching box to the vehicle-side strength member is tightened from the front side of the vehicle in order to enhance the assembling efficiency in the sub-assembly line. In that case, the desorption work becomes difficult.

Further, as the upper surface of the inside / outside air switching box is arranged above the strength member on the vehicle side, the screw fastening portion between the inside / outside air switching box and the blower unit located below the strength member is connected to the strength member on the vehicle side. It is placed close to the peripheral equipment. Therefore, when mounted on the vehicle, this screw fastening part is also disturbed by the vehicle-side strength member and its peripheral devices, making it difficult to remove and install the blower part of the indoor air conditioning unit and the cooler unit part downstream of the blower part. Becomes

Therefore, a blower fan mounted on the indoor air conditioning unit, a blower fan drive motor, an electric resistor for adjusting the rotation speed of the blower fan drive motor, a cooling heat exchanger (evaporator), a cooling heat exchanger. When it becomes necessary to inspect and replace parts such as the temperature sensor, the workability (maintenance) of these parts is greatly deteriorated.

Therefore, in order to cope with the replacement of these parts, a dedicated case for detaching these parts even when mounted on a vehicle is conventionally set as a separate body from the case of the indoor air conditioning unit, and this separate body is installed. There are some that allow you to inspect and replace parts by removing the special case, but this measure will add a separate special case,
