<p><P>PROBLEM TO BE SOLVED: To provide a method and structure for joining members, suitable for reinforcing a shaped material. <P>SOLUTION: An auxiliary member 7 is inserted into holes 9a, 9b, provided at a first place 8a and a second place 8b of a main member 6 such that the forward end of the auxiliary member penetrates through the second place 8b and the base end of the auxiliary member projects outward from the first place 8a. While being rotated, a joining tool 5 is pressed to the forward end of the auxiliary member 7 to soften it by friction heat and plastic flow. Then, the softened material of the auxiliary member 7 is deformed and forced from the hole 9b into the inner side of the main member 6, the joining tool 5 is removed from the main member 6, and the plastic flow portion of the auxiliary member 7 is allowed to solidify. Alternatively, while being rotated, the joining tool 5 is pressed to the forward end of the auxiliary member 7 to soften it by friction heat and plastic flow, the softened material of the auxiliary member 7 is forced from the hole 9a into the inner side of the main member 6 while allowing the softened material of the auxiliary member 7 to deform, the joining tool 5 is removed from the main member 6, and the plastic flow portion of the auxiliary member 7 is allowed to solidify. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
