Golf club
A golf club includes a shaft and a head, the torque of the entire length of the shaft being in a range of 3 to 5°. From viewpoints of a torsional rigidity distribution of the shaft, an integrated value of the torsional rigidity on the grip end side of the shaft is 85% or less 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 40 to 48 mm and a gravity center angle of 22 to 30°.
1. A golf club comprising a shaft and a head,
wherein the shaft has a torque of an entire length thereof of 3 to 5°, wherein in a torsional rigidity distribution of the shaft, an integrated value of the torsional rigidity on the grip end of the shaft is at most 85% of the integrated value of the torsional rigidity of the entire length of the shaft, wherein a measuring method for a torque of the entire length of the shaft is 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 foot·pound (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 a measuring method for the torsional rigidity distribution of the shaft is fixing the shaft at positions 200 mm, 400 mm, 600 mm, 800 mm, and 1,000 mm from the front end of the shaft and turning the shaft with a force of 1 foot·pound (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,
wherein the head has a distance to the center of gravity of 40 to 48 mm and has a gravity center angle of 22 to 30°.
2. The golf club according to claim 1 , wherein the weight of the shaft is at most 65 g.
