図において、７は一枚の平な金属板を角筒状に
折り曲げて形成される金属ケースで、金属板の一
端側の内面２に突起６Ａ，６Ａを設けている。 In the figure, reference numeral 7 denotes a metal case formed by bending a single flat metal plate into a rectangular tube shape, and protrusions 6A, 6A are provided on the inner surface 2 of one end of the metal plate.
そして、金属板の内面２と他端側の外面３が平

As explained above, the present invention involves bending a metal plate sequentially inward from one end to form a rectangular tube shape, and abutting the inner surface of one end of the metal plate parallel to the outer surface of the other end. In the metal case welded by the welding method, a protrusion is provided that abuts the end surface of the other end of the metal plate and regulates the abutting position so that the end surface of one end of the metal plate and the outer surface of the bent metal plate form a flat surface. Since the metal plate is provided on the inner surface of one end side of the metal plate, the end face of the one end side of the metal plate and the outer surface of the bent metal plate are flatly joined, and there is no step on the outer surface of the metal case. .
また、その衝合位置は金属板の内面に形成した
突起により規制した状態で衝合面を溶接すること
ができる。そのため、一枚の平な金属板を角筒状
に折り曲げて、金属板の一端側の内面と他端側の
外面とを衝合して、金属ケースの隣接する２つの
外面、すなわち、上面と側面を外側から押圧する
だけで、金属板の一端側の端面と外面とが必然的
に確実に平坦状に形成される。 Further, the abutting surfaces can be welded while the abutting position is regulated by a protrusion formed on the inner surface of the metal plate. Therefore, a flat metal plate is bent into a rectangular tube shape, and the inner surface of one end of the metal plate is brought into contact with the outer surface of the other end, and the two adjacent outer surfaces of the metal case, that is, the top surface, are By simply pressing the side surface from the outside, the end surface on one end side of the metal plate and the outer surface are inevitably and reliably formed into a flat shape.
したがつて、金属ケースの外表面が適正に形成
されることになり、一枚の平な金属板を角筒状に
折り曲げて位置合わせをする際に、その衝合面を
適正な位置に合致させることが容易になり、位置
合わせを伴う溶接作業が大幅に改善できる。 Therefore, the outer surface of the metal case is formed appropriately, and when a flat metal plate is bent into a rectangular tube shape and aligned, the abutting surfaces are aligned at the appropriate position. Welding work that involves positioning can be greatly improved.
