<P>PROBLEM TO BE SOLVED: To provide a golf club having an easily adjusted club balance and having excellent vibration absorptivity. <P>SOLUTION: The golf club 2 includes a shaft 6, a grip 8 mounted to an end part of the shaft 6, a cavity body 10 mounted to the end part of the shaft 6 to which the grip 8 is mounted, and a weight body 12 detachably mounted to the cavity body 10. The cavity body 10 includes a polymer. Preferably, an outer peripheral surface 16a of the cavity body 10 is mounted to an inner peripheral surface 6a of the shaft so as to abut on the inner peripheral surface 6a. Two or more projections are formed on one of the outer peripheral surface 16a of the cavity body 10 and the inner peripheral surface 6a of the shaft. Two or more recessed parts are formed on the other. The two or more projections are engaged with the two or more recessed parts. Preferably, a complex elastic modulus of the polymer of the cavity body 10 is 1.0×10<SP POS="POST">8</SP>dyn/cm<SP POS="POST">2</SP>or greater and 1.0×10<SP POS="POST">10</SP>dyn/cm<SP POS="POST">2</SP>or less. <P>COPYRIGHT: (C)2012,JPO&INPIT |
