<p>PROBLEM TO BE SOLVED: To enable a golfer to flatten the orbit plane of a club head when the golfer swings a golf club, to allow the club head to run straightforward, to make the impact heavy and strong and to enable the golfer to hit a straight and heavy ball even with a soft shaft. SOLUTION: The surface of the head of the golf club is formed to a streamline shape of small resistance, and the length of the line on the plane on a lower side is made longer than the length of the line on the plane of an upper side so that buoyancy acts strongly to the outer side of the orbit plane when the golfer hits a golf ball by swinging the golf club. Even if the golfer uses the soft shaft, the orbit plane is flattened and the impact is made strong by the buoyancy to the outer side. A head speed is thus increased and the ball is made to fly straightforward and strongly.</p> |
