Zusammenfassung:Two joined hollow frame members have face plates 11,12,21,22 connected in a truss manner by ribs 13A,13B,23A,23B. An end portion of one face plate 11,21 is positioned at the vicinity of an apex of the truss structure. An end portion 12b,22b of the other face plate projects further. The end portions 12b,22b are joined by friction stir joining from above. A connection member 30 is arranged between the upper face plates 11,21 and joined from above by friction stir joining. A load applied in the friction stir joining time is received by the ribs 13A,13B,23A,23B. A lightweight structure and high rigidity performance can be obtained.
