る。2. Description of the Related Art The materials of conventional iron type golf club heads can be roughly classified into metal (specific gravity exceeds 2 g / cm 2 ) and fiber reinforced resin (specific gravity not exceeding 2 g / cm 2 ). Yes, and its structure is solid, hollow,
There are composites. Generally, in the case of materials with a high specific gravity such as metal, there are many solid and hollow structures. The hollow structure is mainly used for expanding the moment of inertia of solid club heads and expanding the sweet area by realizing a deep center of gravity head. It has been. On the other hand, in the case of a material with a low specific gravity such as fiber reinforced resin, the weight of the head is too light and the important function of the golf club, "flying the ball away", cannot be achieved by itself, so it is possible to use a composite with metal. It was necessary to have a predetermined head weight. In the process, many composite iron heads that use materials with a low specific gravity, such as fiber-reinforced resin,
As shown in Figs. 8 and 9, we have created an epoch-making hybrid structure that realizes an ultra-low center of gravity. This is one in which the lower half including the sole is formed of the metal material A, the shaft insertion portion is also formed of this material A, and the other portion is formed of the fiber reinforced resin material B, as shown in FIG. The material B has a two-layer structure of a material B having a low specific gravity and a material A having a high specific gravity.

産の歩留りを悪化させる原因となっていた。In the conventional golf club head having a two-layer structure, the moment of inertia around the center of gravity of the head is small and the ballistic stability function is lacking. The gravity center G of the two-layer structure having different specific gravities is biased toward the heavier specific gravity, so that those having a heavier specific gravity (material A) gather near the center of gravity, and the moment of inertia becomes smaller. Also, the codes a and b in FIG.
The part indicated by (3), that is, the part corresponding to the corner of the head, is liable to be chipped or scratched by the fall of the caddy bag, and there is a problem in quality maintenance. Further, at the boundary between the materials A and B indicated by the reference sign c, there is always a problem of adhesive peeling, which has been a cause of deteriorating the production yield.

Further, since the fiber reinforced resin material is surrounded by the contour portion, the peeling of both materials can be prevented. In addition, since heavy specific gravity (metal material) sandwiches light specific gravity (fiber reinforced resin material), there is heavy specific gravity far from the center of gravity, and it is possible to increase the moment of inertia.

ともできる。As described above, according to the present invention, at least the contour portion of the face excluding the central portion is formed of the metal material. Therefore, the fiber reinforced resin material can be prevented from being damaged, and the fiber reinforced resin material and the metal material can be prevented. It is also prevented from peeling. In addition, because the one with a large specific gravity sandwiches the one with a small specific gravity, there is one with a large specific gravity far from the center of gravity, which can increase the moment of inertia, and the head shake due to the impact at the time of impact. Less and more stable trajectory. In addition, the weight distribution of the metal material makes it possible to design an ultra-low center of gravity and also to design a more stable trajectory. Further, the weight of the head can be easily adjusted by distributing the metal material and the fiber reinforced resin material. For example, by increasing the amount of the fiber reinforced resin material used and reducing the weight of the head, the head speed is improved and the flight distance can be increased.
