Abstract
A flange 52b 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 62c is provided by bending another plate, and a raised portion is provided which protrudes from a parallel side 62b to flange 62c at an end portion of flange 62c. An end portion of flange 52c and end portion of flange 62c are abutted, and end portion of plate 60 is abutted to an outer side of the circular arc portion of flange 52b 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.
