PROBLEM TO BE SOLVED: To improve sealing performance and durability of a door casing for a dish washer. SOLUTION: A top plate panel 34 of the door casing 30 has its outer circumferential part 34a bent perpendicularly downward by the width d. The upper end part 32a of a trunk panel 32 is, at first, bent perpendicularly to the horizontal direction and sequentially its tip part 32b is bent perpendicularly downward by the same width d as the bent width of the outer circumferential part 34a. The outer circumferential part 34a of the top plate panel 34 and the tip part 32b of the trunk panel 32 with the width d abuts on each other to be a coupled shape. The tip of the outer circumferential part 34a and the tip of the tip part 32b of the trunk panel 32 are welded without any clearance. COPYRIGHT: (C)2003,JPO
