发明名称 Golf club
摘要 A golf club, comprises a face member, a hollow head body located behind the face member and having an opening for mounting the face member, a shaft-mounting pipe to be welded to the hollow head body, a shaft fixed to the shaft-mounting pipe and a pipe-retaining groove for retaining the shaft-mounting pipe in such a manner that the shaft-mounting pipe contacts a predetermined position on the hollow head body to which the shaft-mounting pipe is welded to thereby determine the fixing angle of the pipe with respect to the hollow head body. The fixing angle of the shaft mounting pipe is readily set in a state in which the pipe is held in contact with the pipe-retaining groove. The face member and the head body are made of a beta -type titanium alloy, and the hollow head body has a substantially uniform thickness throughout the wall thereof and is thinner than the face member. The shaft-mounting pipe is welded to the pipe-retaining groove, and the face member is welded to the face member mounting portion of the hollow head body.
