PROBLEM TO BE SOLVED: To reduce the number of parts used and improve productivity, by folding the end part of the whole periphery of a panel to a roughly right angle, forming a fist through hole near a cur part, making a second through hole formed at a panel fixing tool and the first through hole meet each other, and tightening and fixing them by bolts. SOLUTION: Panel fixtures 5, 5, 5, 5 are folded in a stepped condition. One end thereof is fixed near four corners of a back plate inside a box body, and the other end thereof is mounted radially in the four-corner direction of the box body. End part of whole periphery of a panel 6 is folded to a roughly right angle. Cut parts 7, 7, 7, 7 are formed at the four corners, and a first bolt through holes 8, 8, 8, 8 are formed near them. A second bolt through holes 9, 9, 9, 9 are formed at the panel fixing tools 5, 5, 5, 5 facing the first bolt through holes 8, 8, 8, 8. The panel 6 and the panel fixing tools 5, 5, 5, 5 are brought into contact with each other. The first bolt through holes 8, 8, 8, 8 and the second bolt through holes 9, 9, 9, 9 are made to meet each other, and tightened and fixed by bolts 10, 10, 10, 10. |
