<p>PROBLEM TO BE SOLVED: To obtain great repulsive force, when a golf ball hits the insert portion of a club face, so that the flying distance of the ball can be increased with usual swing. SOLUTION: A metal head club for a golf has elastic bodies 6, 8, 10 provided inside a club head 4 and a moving axis 16 provided between each of the elastic bodies 6, 8, 10 and a club face 2 for the elastic bodies 6, 8, 10 to be moved, the elastic bodies 6, 8, 10 being arranged in the sequence of a smaller size of shape. The elastic bodies 6, 8, 10 are formed in an elliptically curved plate shape body. The smaller elastic body, when colliding with the larger elastic body, is kicked back with greater repulsive force than input power to obtain great output power so that the flying distance can be increased with the same swing.</p> |
