By the way, since the cover 5 constructed as described above is exposed to the outside air, it is necessary to attach the heat insulating material 12 to the inside of the plate 10 without a gap. The grid-shaped reinforcing member 1
Since 1 is assembled, the structure is complicated and has an uneven shape.

Therefore, one heat insulating material 12 cannot be attached, and a large number of small heat insulating materials 12 are attached side by side. For this reason, the number of types of the heat insulating material 12 is very large, and the shape of the reinforcing material 11 is different depending on each part of the reinforcing member 11. Therefore, there is a problem that a great deal of labor is required including the time and effort for assembling them.

In order to eliminate such a factor of labor and cost increase, a method such as a two-component foam spraying method or high-frequency baking adhesion has been considered, but since it is for a vehicle, it is flame-retardant and non-combustible. It has not been realized yet because of the demand for sex.

The present invention has been made in view of the above circumstances, and an object of the present invention is to significantly reduce the number and types of heat insulating materials of a cover for covering the upper portion of an air conditioner main body, and to reduce the heat insulating material.
