<p>PURPOSE:To prevent the occurrence of a twist due to the bending/twisting load generated during a swing by setting an elastic main spindle at the tip of a shaft to pass the center of gravity of a club head. CONSTITUTION:A golf shaft 12 is formed so that an elastic main spindle at the free end on the fitting side of a club head 14 can be set at an optional position when a grip 13 side is set as a fixed end with a material having anisotropy at least partially, and an elastic main spindle perpendicular to the face 14a of the club head 14 is set to pass the center of gravity of the club head 14, or it is set to pass the geometrical center of gravity of a scoring area 15. A twist generated at the time of a swing or an impact is reduced, the face 14a of the club head 14 is not rotated against the geometrical main spindle of the golf club shaft 12, and a driven ball can be correctly flown toward the required direction.</p> |
