BACKGROUND OF THE INVENTION
The present invention relates to a golf club head, and more particularly to a golf club head having a double face structure.
[0002]
[Prior art]
In a conventional golf club head, for example, in a stainless steel wood club, the thickness of the face portion is formed to be about 3 mm or more in order to require a strength sufficient to withstand an impact when a ball is hit.
[0003]
[Problems to be solved by the invention]
Recent metal wood club heads tend to be larger in order to expand the sweet area, deepen the center of gravity, increase the moment of inertia, etc., and those with a volume exceeding 300 cc have been developed. If the conventional volume of about 180 cc is simply increased without changing the wall thickness, the head weight is increased and the balance is deteriorated, so that it becomes a weight that cannot be shaken by a general amateur golfer. In order to increase the head volume without increasing the head weight, it is necessary to make the thickness of the head as thin as possible. However, there is a limit to reducing the thickness of the face portion due to strength problems.
[0004]
Accordingly, an object of the present invention is to provide a golf club head in which the thickness of the face portion is reduced and the strength is sufficient.

In a golf club head for a wood club provided with a plurality of reinforcing members for connecting both faces, the head body including the front face, the rear face, and the reinforcing member is formed of a metal material, and the reinforcing member is formed of a cylindrical member. The end face of the reinforcing member is exposed on the surface of the front face, and the reinforcing member is provided in a direction substantially orthogonal to the front face surface extending inclined with a loft angle, or provided substantially parallel to the sole, The distance between the face and the front face is 10 to 40 mm.
[0006]
In addition, the face side has a double structure consisting of a rear rear face and a front front face as a ball striking surface, and a plurality of reinforcing members are provided to connect both faces in a space formed between the rear face and the front face. In the golf club head for an iron club, the head body including the front face, the rear face, and the reinforcing member is formed of a metal material, the reinforcing member is formed of a cylindrical member, and the end surface of the reinforcing member is the surface of the front face. A plurality of reinforcing members are provided in the height direction and the horizontal direction of the head main body, respectively, and the lower reinforcing member is lengthened with respect to the upper reinforcing member to lower the center of gravity, and the rear face and distance between front face is gradually increased toward the sole position, 0 the distance between the rear face and the front face.
