툴(10)과, 회전 구동기(8)와, 직동 구동기(7)와, 제1 부재(W1)가 툴(10)과 마주하고, 또한, 제1 부재(W1), 제2 부재(W2) 및 제3 부재(W3)의 순으로 되도록 배치하는 (A)와, 툴(10)을 회전시킨 상태에서, 툴(10)의 선단부가 피접합물(W)의 피접합부(Wa)를 압압하도록, 직동 구동기(7) 및 회전 구동기(8)를 제어하는 (B)와, 직동 구동기(7) 및 회전 구동기(8)를 제어하여, 연화된 제3 부재(W3)가 제2 부재(W2)의 상면보다 상방으로 연장하도록, 툴(10)의 선단부를 제1 위치에 도달시키는 (C)와, 툴(10)을 회전시킨 상태에서 피접합부(Wa)로부터 인발하도록, 직동 구동기(7) 및 회전 구동기(8)를 제어하는 (D)를 실행하도록 구성되어 있는 제어 장치(110)를 구비하는 마찰 교반 접합 장치에 관한 것이다. A friction stir joining device includes a tool, a rotary driver, a linear-movement driver, and a control device. The control device is adapted to (A) dispose so that a first member opposes to the tool, and the first member, a second member and a third member are located in this order, (B) control the linear-movement driver and the rotary driver so that a tip-end part of the tool presses a joined part of a to-be-joined object while the tool is rotated, (C) control the linear-movement driver and the rotary driver so that the third member softened extends above an upper surface of the second member, and the tip-end part of the tool reaches a first position, and (D) control the linear-movement driver and the rotary driver so that the tool is drawn out from the joined part while the tool is rotated.
