Zusammenfassung:PROBLEM TO BE SOLVED: To provide a door sash capable of preventing rust while ensuring an effective manufacturing process. SOLUTION: The door sash 11 formed by one plate material includes: a tubular portion 12; a superimposed portion 13 extended from approximate one corner of the tubular portion 12 and formed by superimposing plate materials; and flanges 14, 15 projecting toward both sides from a rear side of the superimposed portion 13 opposite to the tubular portion 12. A plate material positioned on an outer side of the superimposed portion 13, which is opposite to the tubular portion 12 over the superimposed portion 13, is an end portion of a plate material 193 extending from the tubular portion 12. The periphery of the end portion of the plate material 193 is formed to be in contact with a plate material 192 positioned on the inner side. A superimposed portion 132 of plate materials 191, 192, 193 is continuously welded by continuous seam welding or laser welding in a longitudinal direction. COPYRIGHT: (C)2011,JPO&INPIT
