    • PROBLEM TO BE SOLVED: To provide a frictional agitation joining tool capable of manufacturing a double skin panel joining body being a complete truss structure of continuously constituting a triangular shape in the width direction by including even a joint part, when viewed from the longitudinal direction.SOLUTION: A frictional agitation joining tool FS agitates and joins a joint part 30 of two double skin panels 10 and 20 butted in the width direction by frictional heat, by rotation of a pin-shaped agitation shaft 60 projecting between an upper rotary body 40 and a lower rotary body 50. In the frictional agitation joining tool FS, an upper slide plate 70 is installed via a thrust bearing B1 in a lower end part of the upper rotary body 40, and a lower slide plate 80 is installed via a thrust bearing B2 in an upper end part of the lower rotary body 50. The lower slide plate 80 has a curved surface part 80a continuously adjusted in the longitudinal direction to a shape of an apex angle part 32 of the triangular shape formed of the joint part 30 when viewed from the longitudinal direction of the double skin panels 10 and 20.
    • 要解决的问题:提供一种摩擦搅拌接合工具,其能够从长度方向观察时,通过包括连接部,制造在宽度方向上连续构成三角形的完整的桁架结构体的双层面板接合体。 解决方案:摩擦搅拌接合工具FS通过摩擦热来搅拌和接合两个双面板10和20的在宽度方向上的接合部分30,通过在上旋转体40和 下旋转体50.在摩擦搅拌接合工具FS中,上滑动板70经由推力轴承B1安装在上旋转体40的下端部,下滑动板80经由止推轴承 B2在下旋转体50的上端部分中。下滑动板80具有在长度方向连续调节为顶角p的形状的曲面部80a 从双面板10和20的纵向方向观察时,由接合部30形成的三角形形状的技术32。
