The cover and the third duct cover 125 may include an upper duct cover facing the upper rear side panel SP7 and spaced apart from the upper rear side panel SP7 in a left and right direction.

As illustrated in FIG. 7, the switchboard may further include an outer side cover that covers both the outer side surfaces of the pair of vertical frames and the outer side surfaces of both the duct covers.

The switchboard may include outer front side covers 131 and 132 covering the outer surface of the first side duct D1. The outer front side covers 131 and 132 may cover the outer surface of the first side duct D1 by dividing it up and down.

The switchboard may include an outer center side cover 133 covering the outer surface of the second side duct D2.

The switchboard may include an outer rear side cover 134 covering an outer surface of the third side duct D3.

The side cover may cover the first side duct D1, the second side duct D2, and the third side duct D3 not to be exposed to the outside, and the appearance of the switchboard may be simplified.
