Abstract
At a lower end portion of a hole formed in a heel side portion of a hollow metal golf club head and used to fix a golf club shaft therein, a plug member for closing the same hole is provided so that the shaft-fixing hole does not communicate with a hollow portion on the inner side of the club head. This can prevent the entry of extraneous matter into the hollow portion and the occurrence of an imperfect product which makes a sound.
