<p><P>PROBLEM TO BE SOLVED: To prevent as much as possible damage to heads or collar members when disassembling with heating, to allow reuse of drawn-out collar members, and to achieve a plurality of shaft directions or mounting positions by one collar member. <P>SOLUTION: A golf club has the collar member (14) composed of metal having high thermal conductivity. When the collar member is inserted to a through hole from the sole side, the collar member is engaged with a hole wall of the through hole by a step (20HD), tapering or a screw so that it is not drawn out linearly toward a clown part. The hole wall of the through hole, the collar member and a shaft are fixed by an adhesive, in which adhesive strength decreases at a specified temperature. A tool engaging part (14K) is provided on a lower end of the collar member so that a specified tool is engaged when the collar member is rotated. The through hole has a circular section area so that the collar member is rotated as necessary while facing a circular outer peripheral face. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
