<p>PROBLEM TO BE SOLVED: To provide a golf club with which an impact when it hits a ball can be reduced, and a player seldom hurts his wrists, elbows, or shoulders, and the head speed can be increased, and the carry can be extended. SOLUTION: This golf club has a hollow head with a hosel 2, a shaft cylinder 3 made of non-metallic material which is inserted and fixed into the hosel 2 so that it will not project toward the hollow part 1a of the head 1, and a shaft 4 whose top part 4a is inserted and fixed into the shaft cylinder 3 so that it will not project toward the hollow part 1a of the head 1. When the golf club is swung, the head 1 is pushed back a little for a moment by the impact of hitting, and at the same time, a strong repulsive force is generated at the top part 4a of the shaft 4 mentioned above. And acceleration force is generated by the repulsive force, and a kick-back phenomenon is produced to increase the head speed.</p> |
