Further, the yield strength σ 0.2 of the constituent material of the face portion is higher than the yield strength σ 0.2 of the constituent material of the hosel portion.

割れが発生することを回避することができる。In the present invention, the hosel portion is made of a material having a proof stress σ 0.2 (hereinafter referred to as proof stress) of 30 to 80 kgf / mm 2 and a breaking elongation (hereinafter referred to as elongation) of 10% or more. .. By forming the hosel portion with a material having such characteristics, the head angle (lie angle, face angle, and loft angle) can be adjusted even after manufacturing. That is, in the present invention, since a material having a large elongation is used as the constituent material of the hosel portion, even if the user adjusts the angle of the head, it is possible to prevent the hosel portion from cracking.
【０００７】以下に、本発明における耐力及び伸びの数

耐力は30乃至80kgf/mm2 であることが必要である。If the yield strength of the constituent material of the hosel portion is less than 30 kgf / mm 2 , the yield strength is not sufficient and the hosel portion may be broken at the time of hitting the ball. In addition, the yield strength of the hosel part is 80 kgf / mm 2
If it exceeds, it becomes difficult to bend the hosel part and adjust the angle of the head. Therefore, the yield strength of the constituent material of the hosel part needs to be 30 to 80 kgf / mm 2 .

It is necessary to be above.

単一材料により構成されていることが好ましい。By the way, it may be considered to form the entire head with a material having the above-mentioned characteristics. However, when the proof stress of the constituent material of the face portion is relatively low at 30 to 80 kgf / mm 2 , satisfactory performance as a golf club head cannot be obtained. Therefore, the yield strength of the constituent material of the face portion needs to be higher than the yield strength of the constituent material of the hosel portion. In the present invention, for example, the face portion, the sole portion, the crown portion, and the like may be made of different materials, but in consideration of ease of manufacturing, these portions should be made of a single material. Is preferred.

ましい。The constituent material of the face portion has a yield strength of 80.
It is necessary to exceed kgf / mm 2 , and in order to obtain a better effect, it is preferable that the yield strength is 85 kgf / mm 2 or more. That is, the weight of the golf club head is fixed, and the weight of the head needs to be a predetermined value (about 210 g). Therefore, the bearing capacity of the entire head is 30 to 80 kg.
If an attempt is made to form a material of f / mm 2 , it is necessary to increase the wall thickness in order to maintain the strength of the head, resulting in a smaller head shape. On the other hand, recently, the shape of the golf club head has become larger in order to improve the performance. For materials with a yield strength of 30 to 80 kgf / mm 2 , as described above,
It is not possible to cope with an increase in the size of the head. For example, currently, stainless steel (SUS 630) is mainly used as the constituent material of the metal head. The proof stress of this stainless steel is about 90 kgf / mm 2 , and by making the wall thickness thinner, it is possible to cope with larger heads. That is, by using a material having a higher proof stress than the constituent material of the hosel portion as the constituent material of the face portion or the like, it is possible to cope with an increase in the size of the head. Therefore, the yield strength of the constituent material of the face portion needs to exceed 80 kgf / mm 2 , and in order to obtain a better effect, it is preferably 85 kgf / mm 2 or more.
【００１２】更に、フェース部の伸びが 3％未満の場合
