Even if a robot welding machine is used to streamline the welding operation, the welding operation cannot be completed from only one direction of the control panel housing, and the control panel housing needs to be turned over. As a result, there is a problem that productivity is reduced. Further, in order to correct or remove welding burns (roughness due to oxidation and welding marks due to shrinkage after cooling), it is necessary to grind the weld burns before painting the control panel housing, further reducing productivity. There is a problem that.

[0003] In view of such problems, in recent years, there have been many disclosures of techniques for manufacturing a body such as a control panel by riveting instead of welding. For example, JP-A-10-2
No. 85716 discloses that a frame-shaped upper plate and a pair of side plates formed by removing an opening from a single material and having a bent edge, a bottom plate having a bent edge, and a frame-shaped plate on the front side are rivet members. A fastened housing is disclosed.
