PURPOSE: To enable to supply perception information to show that a golf club was not in the right swing to a golfer. CONSTITUTION: This golf club is constituted of a head 24 and a cylindrical and highly flexible shaft 33 with the flexible point at a comparatively high position, and the shaft 22 generates a twist by influence of an incorrect swing. The golf club is equipped with a flexible handle 26 which can detect the twist of the shaft 22 when a golfer's hand positioned at a second bending point made an incorrect swing. A shock absorbing body positioned at the neck part of the club head 24 is made to prevent the shaft 22 from the being broken even if an abnormally large shock is applied. |
