きる。As is apparent from the above description, the present invention has a main body including a face outer shell, a crown outer shell, and a sole outer shell, and a hosel portion including a neck portion, a shank portion, and the like. It is divided into two parts, these divided bodies are assembled and joined together, and further, if necessary, the main body is divided into two or three outer shell pieces to be formed, and these outer shell pieces are joined together. Since the hosel part is joined together with the hosel part, the hosel part having a complicated three-dimensional curved surface form an integrated structure, and the hosel part does not include a joint part (divided surface). It is possible to prevent a decrease in strength.

少ないために、耐久性を向上させることができる。Further, in the case of molding such a two-piece head, the divided body on the toe side has only a forming method by superplastic working, and the degree of freedom of forming is small and the yield at the time of forming is reduced. Assembling work efficiency can be improved, and since the number of welded portions is smaller than that in the three-divided body and the four-divided body, durability can be improved.

とができる。In the case of molding a three-part head, the two-part body on the toe side is formed by superplastic forming, but it can be formed by partial press forming, and the assembling process is also four.
Since the number of divisions is smaller than the number of divisions, assembly work efficiency can be improved, dimensional accuracy can be improved, cost reduction can be expected, and since there are few welded parts In addition, the durability can be improved.

ができる。Further, in the case of molding a head having four divisions, the three divisional body on the toe side can be formed by superplastic working or a combination of press working and superplastic working. In particular, in the case of molding by pressing, the cost is low and the structure of the three-piece body is simple, so that the molding yield can be increased.
