Golf club

Abstract

A golf club includes a shaft and a head. The shaft has a torque of the entire length of the shaft of from 3 to 5°. In the torsional rigidity distribution of the shaft, an integrated value of the torsional rigidity on the grip end side of the shaft is at least 85% of the integrated value of the torsional rigidity of the entire length of the shaft. The head has a distance to the center of gravity of from 25 mm to 35 mm and has a gravity center angle of from 10° to 20°.

What is claimed is: 
     
         1 . A golf club comprising:
 a shaft having a torque of an entire length of the shaft of from 3° to 5°, wherein in a torsional rigidity distribution of the shaft, an integrated value of a torsional rigidity on a grip end side of the shaft is at least 85% of a integrated value of a torsional rigidity of the entire length of the shaft, wherein a measuring method for the torque of the entire length of the shaft includes fixing the shaft at a position 1,040 mm from the front end of the shaft and turning the shaft with a force of 1 ft-lb (0.1383 kgf·m) applied to a position 25 mm from the front end of the shaft in order to measure a twisted angle of the shaft, wherein the measuring method for the torsional rigidity distribution of the shaft includes fixing the shaft at positions 200 mm, 400 mm, 600 mm, 800 mm, 1,000 mm from the front end of the shaft and turning the shaft with a force of 1 ft-lb (0.1383 kgf·m) applied to a position 25 mm from the front end of the shaft in order to measure the twisted angle of the shaft and calculate the torsional rigidity at each measurement position, wherein the integrated value of the torsional rigidity of the entire length of the shaft is a value obtained by integrating the torsional rigidity from 200 mm from the front end of the shaft to 1,000 mm from the front end of the shaft, wherein the integrated value of the torsional rigidity on the grip end side of the shaft is a value obtained by integrating the torsional rigidity from 400 mm from the front end of the shaft to 1,000 mm from the front end of the shaft; and   a head having a distance to a center of gravity of from 25 mm to 35 mm and having a gravity center angle of from 10° to 20°.   
     
     
         2 . The golf club according to  claim 1 , wherein the shaft having a weight of at least 50 g.
