Abstract:
An auxiliary member is inserted into holes of opposite portions of a main member such that opposite ends of the auxiliary member extend outwardly through the holes. A joining tool is pushed, while being rotated, against one of the ends of the auxiliary member, so that the material of the auxiliary member softened due to frictional heat and plastic flow is deformed and pushed inside the main member via the hole. The tool is released to allow the plastic flow portion of the auxiliary member into solidification. Then, a similar operation is performed with respect to the other end of the auxiliary member.
