Abstract
In construction of a golf club head having a fiber reinforced plastic shell, the neck section of the shell provides the first hold and an inward bulge on the sole side section of the shell provides the second hold, both for the club shaft so that presence of a dual hold joint structure enables effectual energy transmission at hitting balls and reliably prevents accidental separation of the club head from the club shaft.
