Abstract
Face platesandof a hollow shape memberare abutted against face platesandof a hollow shape member. Groovesformed to said face platesandat the abutted region receive projectionsformed to said face platesand. A connecting plateorthogonal to said face platesandis provided to the hollow shape member. There is no connecting plate orthogonal to face platesanddisposed on the end of the hollow shape member. Friction stir welding heat causes the face plate() to move toward the thickness direction of hollow shape membersand, but such movement is suppressed by the grooveand projection. Thereby, the abutted region is welded flatly. Since the hollow shape memberrequires no connecting plate corresponding to plate, the welded members are light in weight.
