Zusammenfassung:To a plate 50, a flange 52b provided by bending the plate, a flange 52 being orthogonal substantially to the flange 52b and provided bending the plate, and a recessed portion except for a flange between two flanges are provided. To a plate 60, a flange 62c provided by bending the plate, a raised portion protruded from a parallel side 62b to a flange 62c at an end portion in a longitudinal direction of the flange 62c and a vicinity of the end portion are provided. An end portion in a longitudinal direction of the flange 52c and the end portion in the longitudinal direction of the flange 62c are abutted and further an end portion of the plate 60 is abutted to an outer side of a circular arc portion of the flange 52b from the plate. The raised portion is inserted and abutted to the recessed portion and the respective abutted portions are welded. In a case where two plates in which a flange is provided by bending the plate are intended to a welding, an occurrence of a space in a welding portion can be prevented.
