US Patent 6878073 Wood golf club

A wood golf club called a metal wood which suppresses the deformation of a head body at the time of impact, thereby effectively elastically deforming a face to thereby elongate a travelling distance of a ball. An outer shell of a head 1 is constructed of metallic shell members, thus defining a hollow interior 11 inside the head 1. A tabular reinforcing member 20 is provided nearly along a cross-sectional area of the hollow interior 11 defined in a toe-to-heel direction, a preset distance away from the face 2. Thus, the deformation of a sole 4 and a crown 5 can be suppressed, while permitting the sufficient elastic deformation of the face 2.
