Abstract
A golf club head having a metallic and hollow head body, of which the volume is capable of being enlarged without decreasing the connection strength of a shaft. A hosel is formed thicker at its lower end than at its upper end, while a lower end of a shaft is provided evenly relative to a lower end of the hosel, or otherwise, protrudes slightly downward relative to the same. Thus, a length of the shaft can be saved without decreasing the connection strength of the same to the head body. In another embodiment of the invention, a collar is preformed at an intermediate portion of the hosel, thereby improving the connection strength of the hosel and shaft to the head body, and at the same time, metallic cladding will be unnecessary in manufacturing a golf club head, thereby improving its productivity.
