TWI253355B - Vibration absorbing structure for golf club shaft - Google Patents

Abstract

A golf club shaft comprises a shaft tube, and a light-weight damper. The shaft tube has a tube wall and an inner space surrounded by the tube wall. The shaft tube connects to a club head in one end, and connects to a grip in the other end. The light-weight damper is received in the inner space of the shaft tube, and partially attached to an inner circumference thereof. Thereby, when the club head strikes a golf ball and generates vibrations, the light-weight damper can efficiently absorb vibrations transmitted from the club head to the shaft tube.
