Abstract: Provided is a friction stirring rotary member which makes high-strength joining possible while suppressing the occurrence of joining defects in friction stir joining. A method for manufacturing a joining component comprises a reception step in which a semi-finished product supplied from a pre-process facility of a production line is received by a joining device in the production line, a joining step in which friction stir joining of a member to be joined and the semi-finished product received via the receiving step is performed by a joining device to obtain a joining component, and a discharge step in which the joining component obtained via the joining step is discharged toward a post-process facility of the production line. The joining device includes an output shaft, a driving mechanism configured to cause the output shaft to rotate, and a friction stirring rotary member attached to the output shaft so as to rotate due to rotation transmitted from the driving mechanism. The friction stirring rotary member is configured such that, when said rotary member is attached to the output shaft, play is generated between the output shaft and a pin part inserted into the member to be joined during friction stirring, the play enabling vibration of the pin part relative to the output shaft.
