Connecting portion 108-2 then extends the area between flange 101-25 and front panel 101-2 of housing 101. FIG. That is, the front panel 101-2 of the housing 101 is suspended on the front cross member 108 and secured by bolts to complete the assembly. Using this method, a single front panel made of sheet metal is suspended on the front cross member 108 . After completing the suspension, the flange and the front panel 101-2 of the housing 101 are kept parallel, and the suspension effect is stable and reliable.
