Abstract
A hollow frame member is constituted by joining with a truss shape by ribs 13, 13A, 13B (23, 23A, 23B) between two face plates 11, 12 (21, 22). An end portion of one of the hollow frame member 10 is connected according to the rib 13A for constituting the truss. A face plate 21 of another hollow frame member 20 is joined at a vicinity of an apex of the truss of the hollow frame member 10. A face plate of the hollow frame member 10 is joined at a vicinity of an apex of the truss of the another hollow frame member 20. A load during a friction stir joining is received according to the ribs 13A, 13B (13A, 23B). Since the truss structure is formed totally, the light weight structure and the high rigidity performance can be obtained.
