Beschreibung
Zusammenfassung:	A flange 52 b is provided on a plate by bending the plate, the flange being substantially orthogonal to the plate, and a recessed portion, where the flange is missing, is provided between two flanges. A flange 62 c is provided by bending another plate, and a raised portion is provided which protrudes from a parallel side 62 b to flange 62 c at an end portion of flange 62 c. An end portion of flange 52 c and end portion of flange 62 c are abutted, and end portion of plate 60 is abutted to an outer side of the circular arc portion of flange 52 b from the plate. The raised portion is abutted to the recessed portion, and respective abutted portions are welded. Where two plates in which a flange is provided by bending the plate are intended to be welded, the occurrence of a space in a welding portion can be prevented.
