PROBLEM TO BE SOLVED: To perform friction agitation joining capable of reducing a strain in joining many hollow shape materials. SOLUTION: Seven sets of friction agitation joining devices to join seven hollow shape materials 10, 20, 30, 40, 50, 60, 70 are arranged to a running body 320. Rotary tools of the friction agitation joining devices respectively correspond to the joining line of the hollow shape materials 70, 60, the joining line of 50, 40, the joining line of 30, 20. Holding devices 350, 360 to hold the hollow materials correspond to these joining lines. The joining lines of members adjacent to holding joining lines are held by the holding devices 350, 360. Joining is performed at this state. Next, the friction agitation joining devices and the holding device 350, 360 are made conform to the joining lines of the position shifted by one line, thus, joining is performed. |
