<p><P>PROBLEM TO BE SOLVED: To provide a golf club for which a head and a shaft are freely detachable. <P>SOLUTION: A hosel portion 22 has a screw portion 32 and a hosel hole 28. The screw portion 32 of a screw member 10 and a screw portion 26 of the hosel portion 22 are coupled to each other. An inner member 8 has a shaft inserting hole 40 and a lower surface 42. A shaft 6 and the shaft inserting hole 40 are fixed through bonding or the like. The lower surface 42 of the inner member 8 has a plurality of first surfaces and a plurality of second surfaces. The first surface is a parallel surface with a central axis or a tilted surface which is tilted to a circumferential direction. The first surface is extended in such a direction as to enable, together with a receiving surface, a generation of a force capable of inhibiting a relative rotation of a head and the shaft in hitting. The second surface is extended in a closer direction to the circumferential direction as compared with the first surface. By an engagement of the receiving surface and the lower surface 42, the relative rotation of the shaft 6 and the head 4 is inhibited. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
