摘要： An object of the present invention is to provide a rotary tool, a joining device, and a joining method that can carry out load control while mounted to a machining center. The present invention is characterized by the configuration including: a main body (10) having a fixed unit (11) and a rotary shaft (12); a stirring pin (50) that is arranged on the main body (10) so as to be rotatable and to be movable relative to an axial direction of the rotary shaft (12), and that is inserted into a joint member (2) to perform friction stirring; and a shoulder (60) that is formed separately from the stirring pin (50), that is arranged on the main body (10) so as not to receive a rotary force from the main body (10) but to be movable relative to the axial direction of the rotary shaft (12), and that presses the joint member (2) while in contact with the joint member (2), wherein the stirring pin (50) and the shoulder (60) are mounted to form an assembly (70) so as to be relatively movable and to move integrally in the axial direction of the rotary shaft (12), and the rotary tool further includes a first elastic member (51) that biases the assembly (70) toward a distal-end side of the stirring pin (50) relative to the axial direction of the rotary shaft (12).

摘要： An object of the present invention is to provide a rotary tool, a joining device, and a joining method that can carry out load control while mounted to a machining center. A rotary tool includes: a main body (10) having a fixed unit (11) attached and secured to a joining device (3), and a rotary shaft (12) for transmitting a rotary force from the joining device (3); a stirring pin (60) that is arranged on the main body (10) so as to be rotatable by receiving the rotary force from the main body (10) and to be movable relative to an axial direction of the rotary shaft (12), and that is inserted into a joint member (2) to perform friction stirring on the joint member; a shoulder (70) that is formed separately from the stirring pin (60), that is arranged on the main body (10) so as not to receive the rotary force from the main body (10) but to be movable separately from the stirring pin (60) relative to the axial direction of the rotary shaft (12), and that presses the joint member (2) while in contact with the joint member (2); and a first elastic member (61) that biases the stirring pin (60) toward a distal-end side relative to the axial direction of the rotary shaft (12).
