To do this, after loosening and removing the upper and lower screws 90 and 94, the upper end of the side panel 50 is connected to the side panel 87 of the top plate 85. The reinforcing member 60 can be removed while being pulled downward from the gap 88 between the reinforcing member 60 and the hanging plate 80.
When the maintenance is completed and the side panel 50 is attached again, the side panel 50 may be attached as described above using the hanging end of the hanging plate 80 as a guide.

As described above, according to the present embodiment, since the heat insulating space 93 is secured on the upper surface side of the partition plate 65 provided in the reinforcing member 60, the exhaust heat rising on the ceiling side of the machine room 40 causes the ceiling The end of the plate 85 on the machine room 40 side is prevented from being heated. As a result, the entire surface of the top plate 85 can be used as a table.
The heat insulation space 93 also functions as a wiring space, and an electric wire to be wired to the machine room 40 side such as an electric wire drawn out from the cooler chamber 20 is wired through the wiring space. An electric wire can be wired without using a special fixture, and wiring work is also simplified. Further, since the electric wire is prevented from being directly exposed to exhaust heat, the service life can be extended.

  The upper end portion of the side panel 50 is attached by inserting the upper end portion of the side panel 50 into the gap 88 between the side plate 87 of the top plate 85 and the hanging plate 80 of the reinforcing member 60 and fastening them together with screws 90. However, since the lower end of the drooping plate 80 protrudes downward from the lower end of the side plate 87, the upper end of the side panel 50 is applied to the protruding portion of the drooping plate 80, and then slides on the drooping plate 80. The upper end portion of the side panel 50 can be inserted into the gap 88 between the side panel 87 of the top plate 85 and the hanging plate 80 of the reinforcing member 60 by itself. Therefore, after the side panel 50 is removed for maintenance or the like, it is possible to easily perform the work of attaching it again.
