PURPOSE:To see that it can cope with many specifications with few kinds by obviating the necessity to enlarge the cut area of a metallic plate, and obviating the necessity to make it by welding an operation part. CONSTITUTION:A box 1, the front of which opens, is made by bending metallic plates and assembling them. An operation part 2 for control and operation is made by bending metallic plates and assembling them. The operation part 2 is attached to the topside of the box 1. For metallic plates for making the box 1 and the operation part 2 as separate bodies, the curt areas get off small. Since the box 1 and the operation part 2 are made by bending and assembling the metallic plates, the operation part 2 can be attached to the box 1 by screwing of a bolt and a nut or the like. By the combination of the boxes 1 and the operation parts 2, many specifications of boxes for control panels can be made. |
