Abstract
A golf club 2 is provided with a head 4 having a hosel hole 18 and a shaft 6. The golf club 2 has a mounting/detaching mechanism detachably mounting the head 4 and the shaft 6 to each other. The mounting/detaching mechanism can fix the shaft 6 to the hosel hole 18 of the head 4 at a plurality of circumferential mounting positions. The shaft 6 has anisotropy producing coupled deformations of bending and torsion. Preferably, an angle θ1 between an axis line of the shaft 6 and an axis line of the hosel hole 18 is 0 degree. Preferably, a bending torsional amount of the shaft 6 is equal to or greater than 0.5 degree.
