Abstract

A metallic golf club wood head comprises a substantially planar face member welded to a container-shaped rear shell member having an open front face. A shaft connecting portion 7a is forged integrally with an upper portion of the face member 11a. A cut-out 14a is formed in an upper face of a front side of a rear shell member 12a for accommodating a lower portion of the shaft connecting portion 7a. As a result of this construction the number of structural members is reduced and the strength of the shaft connecting portion 7a is increased. Furthermore, the loft angle can be adjusted when manufacturing the face member 11a for example by forging. Moreover, since it is sufficient for the shaft connecting portion 7a to be formed at the top of the head only, the front side of the head can be lightened and the "sweet area" increased.

Claims

1. A golf club wood head having a hollow metallic body with a face on a front surface thereof and a shaft connecting portion protruding upward from an upper portion of a heel side, said head comprising:

a substantially planar face member, and a container-shaped rear shell member having an open front face connected to a rear side of the face member, wherein said shaft connecting portion is integrally formed with said face member on an upper portion of a heel side thereof and protruding rearward therefrom, while a cut-out is formed in said rear shell member in a heel side on an upper face of a front side thereof, for accommodating a lower portion of the shaft connecting portion formed on said face member.

2. A golf club wood head as claimed in claim 1, wherein a separate lower rear side part of said shaft connecting portion is formed on said rear shell member.

3. A golf club wood head as claimed in either of claim 1 and claim 2, wherein a recess is formed in a rear face of said face member.
