るために量産が困難であるという欠点がある。2. Description of the Related Art As a golf club head, a solid club head manufactured by cutting natural persimmon (persimmon tree) has been widely used since ancient times. This persimmon head uses natural wood and is solid, so the shot feeling is soft and the impact at the time of hitting is small, so there are many lovers, but since it is manufactured by hand by a craftsman from natural wood, There is a disadvantage that mass production is difficult.

いことから、十分な効果は得られていない。However, the above-mentioned metal hollow golf club head only reduces vibration after the face is deformed by impact after hitting a ball. Sufficient effects have not been obtained because the deformation of the face portion itself, which is the biggest factor that causes the difference in shot feeling between the golf club head and the persimmon head, cannot be suppressed.

５５０ＨＢ程度である。The present invention is a golf club head having a hollow metal shell such as a so-called hollow iron head, utility club head, or wood-type metal head having a hollow portion on the back surface (back surface) side of the face portion. Examples of the metal material forming the outer shell of the head main body include maraging stainless steel, stainless steel such as SUS630 and SUS431, maraging steel, copper alloys such as beryllium copper, and titanium alloys. These metallic materials usually have a specific gravity of 7.8 to 8.4 and a Brinell hardness of 350 to
It is about 550HB.

を勘案して適宜限定される。With respect to the head body, it is effective to form the outer shell of the crown and the like thin so as to improve the vibration absorption and shot feeling. As for the thickness of the outer shell constituting the head main body, the thickness of the face portion is 1.5 to 3.5 mm, particularly 2 to 3 mm.
It is preferable that The thickness of the crown and side portions is preferably 0.5 to 1.5 mm. The thickness of the sole portion is preferably 0.8 mm or more (for example, 0.8 to 4 mm) in order to ensure a thickness that does not cause depression when hit with a duff or bear ground (on the soil). It is appropriately limited in consideration of the weight.

メタルヘッドに好適である。By making the head body thinner in this way, it becomes possible to manufacture a large wood-type metal head. Also, it is possible to provide a weight having a higher specific gravity than the head body in a necessary portion, or to make the head body thicker. Since it can be designed, it is particularly suitable for utility club heads and wood-type metal heads.

効である。As described above, a thin golf club head is
Since the ball is used in an area where the head speed is high, the face surface is likely to be deformed when the ball is impacted. Therefore, the present invention is particularly effective for a golf club used in a so-called high head speed region having a head volume of 65 cm 3 or more and 400 cm 3 or less and a loft angle of 24 ° or less.

め、ヘッド重量を軽くした場合、インパクト時に受ける
ヘッドの衝撃は大きくなり、より打球感が悪くなる。That is, by designing the thickness of the outer shell of the golf club head to be thin or reducing the weight of the head,
Since the face is easily deformed when the ball impacts the ball and the thickness of the crown etc. is formed thin,
The head as a whole tends to vibrate and the feel at impact deteriorates. Further, if the club length is increased, unless the head weight is lightened, the swing balance of the club becomes heavy and it is difficult to swing, so if the head weight is lightened, the impact of the head received at impact becomes large, making the shot feeling worse Become.

も、ヘッドの重心位置が深くなりにくい。The metal material constituting the impact buffering member is as follows.
It is preferably a metal material having a specific gravity of 5 or less, particularly 1.8 to 3.0, and specifically, metals and alloys such as pure titanium and pure aluminum which are easily plastically processed, and magnesium alloys which are easily damped by vibration. preferable. Further, porous titanium, aluminum and alloys thereof are also preferable. The bulk specific gravity at this time is preferably from 0.1 to 1.0. Further, this metal material has a Brinell hardness of 150 HB or less, preferably 120 HB or less, particularly preferably 80 HB or less. In the present invention, vibration is fixed to fix the impact buffer member made of such a soft metal material. Easy to absorb,
Further, since the specific gravity is small, even if the head is fixed to the back surface of the face portion, the position of the center of gravity of the head does not easily become deep.
【００２２】このような打撃緩衝部材をフェース部の背

The head is integrated with the other parts by welding. The method of manufacturing the face portion as a separate body as described above is a preferable method because the impact buffering member can be easily fixed. First, a hollow head body is made of a metal material having a high melting point by using a lost wax method or the like, and thereafter, a metal material having a low melting point is poured to form a shock absorbing member.
【００３２】この時の融点の温度差は、少なくとも１５
