<p>The present invention provides a golf club, in which a plurality of protruding ribs (1) is provided on an inner or outer surface of a shaft (100). In the present invention, because the protruding ribs (1) are provided in the shaft (100) of the golf club, the restoring force of the shaft is increased, thus increasing the ball driving force and the distance that the ball is driven. Furthermore, when executing a golf swing or striking the ball, the shaft (100) is prevented from twisting, so that the ball is driven in the correct direction. In addition, the strength of the shaft is increased.</p> |
