In the publication, an air conditioning unit or the like is attached to a steering member, and a unit assembly is formed by attaching a display device to the air conditioning unit.
There has been proposed a device in which an instrument panel is attached so as to cover the unit assembly after the unit assembly is attached to a vehicle body.

In general, an air conditioning unit is an air conditioning component such as an inside / outside air switching device for adjusting the ratio of introduction of inside air to outside air, a blower, a cooling heat exchanger, a heating heat exchanger, and a blowing mode switching device for switching a blowing mode. Are arranged in series with respect to the flow of the wind, but in the above-described module configuration, maintenance is required for each air-conditioning component by removing the instrument panel and then performing maintenance. It is necessary to remove the air conditioning components from the air conditioning unit.

[0004]

However, if the instrument panel is raised and lowered one by one at the time of maintenance, the work efficiency is poor, and the instrument panel itself is large and heavy, so that the instrument panel is heavy. It was not easy to attach and detach, and it was a major obstacle during maintenance. Therefore, maintenance is becoming an important issue in modularizing the air conditioning unit and the instrument panel.

Therefore, in the present invention, in particular, the heating heat exchanger and the blow-out mode switching device are arranged at substantially the same position in the vehicle width direction, and the inside / outside air switching device, the blower, and the cooling heat exchanger are heated. The heat exchanger is offset from the heat exchanger in the vehicle width direction, and the blower and the cooling heat exchanger are arranged in the vehicle width direction. When placing the air conditioning unit configured inside the instrument panel inside the instrument panel, repair and replacement of the air conditioning parts can be easily performed without lowering the instrument panel, and maintenance It is an object of the present invention to provide a vehicle air conditioner capable of improving workability and reducing maintenance costs.
