<p>PROBLEM TO BE SOLVED: To provide a golf club in which an insertion hole, whose opening side is a large diameter portion and whose inner part side is a small diameter portion, is placed in the metal hosel portion of a head, a ferrule cylindrical foot portion, in which a cylindrical foot portion is integrally projected in the bottom of a circular truncated cone-shaped cap portion, is inserted in the large diameter portion and a shaft passing through the inside of the ferrule cylindrical foot is inserted in the small diameter portion, wherein coming out of the head from the shaft is prevented and easy movement of the shaft before adhesive hardening immediately after adhesion of the head to the shaft is prevented. SOLUTION: A ferrule is limited to the circular truncated cone-shaped cap portion, a synthetic resin cylindrical sleeve is inserted in the large diameter portion of a hosel portion insertion hole, after fixing, the shaft is inserted in the inside of the cylindrical sleeve and the small diameter portion of the insertion hole and is fixed with an adhesive to the insides of both. It is desirable that a projection for holding the shaft is placed in the inside of the synthetic resin cylindrical sleeve.</p> |
