PROBLEM TO BE SOLVED: To provide a rotary frictional joining method, in which one member is held and rotated in the radial direction thereof without grasping it and which can eliminate the need to carry out positioning of the member in the rotation direction.;SOLUTION: This rotary frictional joining method comprises, while rotating one member 12, 41 around an rotation axis O, pressing and joining the member against the other member 11 in parallel to the rotating axis O. In this case, a protrusion part 131c, which has been formed in a transmission mechanism 13 for transmitting rotary power to the one member 12, 41 and has been protruded toward the one member 12, 41 side in parallel to the rotating axis O, is bitten into the one member 12, 41.;COPYRIGHT: (C)2008,JPO&INPIT
