<p>PROBLEM TO BE SOLVED: To prevent sounding, to allow weight regulation with high accuracy and to improve productivity. SOLUTION: A hollow body which constitutes a head 1 by combining plural metallic shells is formed. A solvent type or water-soluble tacky adhesive having a flow property at an ordinary temperature is injected into the hollow body from an aperture of a hosel 9 possessed by this hollow body. The solvent or moisture is thereafter annihilated from this tacky adhesive, by which the flow property is lost and the tacky adhesive is surely fixed to the inside of the hollow body.</p> |
