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.

主权项 1. A golf club comprising: a hosel portion which is provided as an integral body or a separate body in a head main body and has a shaft insertion hole formed as a through hole shape; a closed-end tubular plug member which is fixed to a leading end portion of a shaft and is inserted to said shaft insertion hole; an angle adjusting member which is inserted to said shaft insertion hole from a lower end opening thereof and is provided with a come-off preventing engagement portion so as to prevent from coming off upward; and a fixing bolt which is inserted from a bolt insertion hole provided in said angle adjusting member and is screwed into a female thread portion provided in an end surface portion of said plug member, thereby detachably fixing said angle adjusting member and a plug member to said hosel portion, wherein a spherical bearing structure is provided in an upper end opening peripheral edge portion of said shaft insertion hole and an outer peripheral portion of said plug member corresponding thereto, and a rotation preventing structure for preventing rotation of said plug member with respect to said hosel portion is provided, wherein a diametrical gap is set between an outer peripheral surface of a lower end portion of said plug member which is inserted to said shaft insertion hole and an inner peripheral surface of said shaft insertion hole corresponding thereto, wherein said angle adjusting member is provided with a spacer portion which positions the lower end portion of said plug member in a state of being biased in any direction of a diametrical direction within said shaft insertion hole by being inserted to said diametrical gap in a part on the circumference, and wherein a fixing angle of said head main body with respect to said shaft is adjustable on the basis of what position on the circumference said spacer portion is inserted to said diametrical gap at.
