実上不可能となる。Therefore, the strength of the hosel portion of the head is lowered, and the head is easily damaged or broken by the impact at the time of hitting the ball. Therefore, not only the durability is deteriorated, but also the lie angle and the loft angle are adjusted. If it is bent at times, cracks and scratches will occur at the joints, making it virtually impossible to adjust the lie angle and loft angle.

The toe portion side divided body and the heel portion side divided body composed of the face outer shell, the crown outer shell, each part of the sole outer shell of the head body and the hosel portion are formed by dividing into two parts. It is configured by joining the bodies.

2. Gas blow molding is performed under the setting condition of molding time of 60 minutes.

強度の低下を防止することができる。As is apparent from the above description, according to the present invention, basically, the toe portion side of the head and the heel portion side including the hosel portion are separately formed, and these divided bodies are assembled to each other. Joined, and further, if necessary, the divided body on the toe side is divided into two or three outer shell pieces to be formed,
These outer shell pieces are joined and integrated. Since the outer shell pieces are joined to the divided body on the heel portion side, the heel portion side including the hosel portion having a complicated three-dimensional curved surface form an integral structure and are joined to the hosel portion. Since no part (divided surface) is included, it is possible to prevent a decrease in strength as before.

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-piece 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.
