Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to various golf club heads (hereinafter referred to as golf club heads) such as iron clubs, wood clubs, metal wood clubs and FRP wood clubs. More specifically, the present invention is based on a golf club head of one basic model, and a face member capable of forming various loft angles and / or face orientation angles is fixed to the wall surface of the head on the ball striking face side. By doing so, the present invention relates to a golf club head capable of achieving a large number of developments in the loft angle and face orientation angle (hereinafter referred to as multiple developments).

2. Description of the Related Art A conventional golf wood club in which a face member is mounted in a concave portion of the face surface or fixed to the entire face surface has a predetermined loft angle formed in the wood club itself. Therefore, when trying to expand the loft angle in multiple ways, a wood club having a desired loft angle is manufactured, and a face member according to the related art, that is, a member having a single wall thickness of a desired shape is typically used. A face member having a uniform thickness is attached. Therefore, in this type of golf wood club, the multi-expansion of the loft angle is complicated because the wood club itself must be provided with a desired loft angle according to the content of the multi-expansion (type of loft angle). It is accompanied by Further, when the wood club is not of the type described above, for example, when it is attempted to deform the neck portion to expand the loft angle in many ways, it is difficult or impossible to deform the neck portion.

Furthermore, in the prior art, when attempting to develop multiple face orientation angles, the same difficulties as those of the above-described multiple development of loft angles are involved. That is, also in this case, for example, the face orientation angle of the wood club must be manufactured with a predetermined face orientation angle according to the content of the multi-expansion (type of face orientation angle). In the present invention, the face direction angle means that the characteristics of the face surface have a strong tendency to hit the ball in the direction of the square when hitting the golf ball, or have a strong tendency to rotate the ball by the hook, or It is a characteristic that the tendency of slicing the ball is strong. Therefore, for example, when the face surface has a strong tendency to rotate the ball by the hook, the face surface is expressed as having the hook direction angle. It is needless to say that the hook direction angle is relative and that there exists a hook direction angle of a desired grade (stage). The same applies to the slice orientation angle.
