Abstract
In construction of a joint structure between a hosel, a shaft and a ferrule, a rugged engagement is formed between the hosel and the ferrule in order to withstand a force at shooting balls which tends to move the ferrule apart from the hosel. The rugged engagement consists of at least one projection formed on one of the ferrule and the hosel and a recess formed in the other of the ferrule and the hosel.
