<P>PROBLEM TO BE SOLVED: To provide a box for storing electric apparatus that has a sufficient strength, being excellent in appearance. <P>SOLUTION: A sheet of steel plate is processed to form a U-shape cover member 5, including a ceiling plate 3 and succeeding left and right side plates 4 and 4. A sheet of steel plate is processed to form an L-shape body member 8, including a back plate 6 and a succeeding bottom plate 7. The cover member and the body member are united together to form a box body 1 including an opening part on its front side. The opening part is fitted with a door 2. The front side edge of the body member 8 and the cover member 5 are bent to form a frame at the periphery of the opening part which the door 2 enters. A welding piece is extended inside the box by the amount of thickness of the steel plate from either the frame of the body member 8 or that of the cover member 5 at the joint part of the frame. <P>COPYRIGHT: (C)2009,JPO&INPIT |
