摘要:
In order to enlarge a sweet area on a ball hitting surface of a golf clubhead, composite structures of two different specific gravities are utilized in addition to structural devices for fixing composite parts. The center of gravity of a golf clubhead is capable of being further distant from a face by utilizing said composite structures, for example, a balance weight fitted into a head body, a face fitted into a head body, a window-like hole provided in a head body etc. In the case of fitting a face into a head body, the specific gravity of said face is smaller than that of a head body, which is provided with a window-like hole, and/or a back crust therein, whereby golf clubheads with ultra wide sweet area can be obtained.
