PROBLEM TO BE SOLVED: To friction stir join a gusset and a cross member with sufficient coupling strength.SOLUTION: A notch-shaped joint recessed portion 31 is formed on a gusset side attaching plate portion 25 of a gusset 4. In a combination state in which a cross member side attaching plate portion 17 of a cross member 3 enters the joint recessed portion 31, an outside surface of the cross member side attaching plate portion 17 opposes to an inside surface of the joint recessed portion 31 to approach or contact with each other, and an upper surface 18 of the cross member side attaching plate portion 17 is disposed on the generally same surface as an upper surface 27 of the gusset side attaching plate portion 25. The inside surface of the joint recessed portion 31 and the outside surface of the cross member side attaching plate portion 17 are linearly joined by friction stir joining along a boundary 35 between the upper surface 27 and the upper surface 18 in the combination state.SELECTED DRAWING: Figure 1

    【課題】ガセットとクロスメンバとを十分な結合強度で摩擦攪拌接合する。【解決手段】ガセット4のガセット側取付板部25には切欠き状の接合凹部31が形成され、クロスメンバ3のクロスメンバ側取付板部17が接合凹部31に侵入した組合せ状態で、クロスメンバ側取付板部17の外側面は接合凹部31の内側面と対向して近接又は接触し、クロスメンバ側取付板部17の上面18はガセット側取付板部25の上面27と略同一面に配置される。接合凹部31の内側面とクロスメンバ側取付板部17の外側面とは、上記組合せ状態での上面27と上面18との境界35に沿った摩擦攪拌接合によって線状に接合される。【選択図】図1
