发明名称 GOLF CLUB
摘要 Disclosed is a golf club having a structure with which optional angle adjustment can be easily and firmly performed by a user himself/herself without changing the direction of a shaft along the circumference thereof with respect to a head. To this end, the distal end portion of the shaft to which a plug member is fixed is fitted into a shaft insertion hole of a hosel portion from above, an angle adjusting member is fitted from below, and a fixing bolt is fitted into a bolt insertion hole of the angle adjusting member and screwed into an internal thread portion of the plug member. A radial clearance is left between the outer circumferential surface of a lower end portion of the plug member fitted into the shaft insertion hole and the inner circumferential surface of the shaft insertion hole corresponding to the outer circumferential surface, and a spacer portion partially formed on the angle adjusting member along the circumference of the angle adjusting member is fitted into a part of the radial clearance along the circumference of the radial clearance. The fixing angle of the head body with respect to the shaft can be adjusted by the circumferential position of the spacer portion fitted into the radial clearance.
