<p>PROBLEM TO BE SOLVED: To provide a mechanism for shifting the center of gravity which can shift the center of gravity during a swing keeping the weight light and the balance of the swung club member. SOLUTION: This golf club has a shaft 1, a head 2 provided at one end of the shaft 1, and a grip provided at the other end of the shaft 1. A hollow part 1a is formed in the shaft 1, and a hollow part 2a is formed in the head 2, and the head 2 is coupled with the end of the shaft 1 so that the hollow part 2a is continued to the hollow part 1a. Thus, plural lead small balls 5 (medium of shifting of the center of gravity) are put in the hollow parts 1a, 2a.</p> |
