GOLF CLUB HEAD
First Claim
1. A combination of a golf club head and a gravity point adjuster, whereinthe golf club head comprisesa hollow structure having an insertion-opening in the outer surface of the golf club head,a quick-release lid of the insertion-opening, anda tubular part disposed in a hollow of the hollow structure and having a bottomed hole with which the insertion-opening communicates, andthe gravity point adjuster comprisesa heavy-weight member having a specific gravity and a length L2,a light-weight member having a specific gravity less than that of the heavy-weight member and a length L1 more than the length L2, andan elastic member having a specific gravity less than that of the heavy-weight member, and an elastic modulus lower than those of the heavy-weight member and light-weight member, whereinthe heavy-weight member, the light-weight member and the elastic member are inserted in the bottomed hole by the use of the insertion-opening so that their relative positions relative to the bottomed hole can be changed.

Abstract
A golf club head comprises: a hollow structure having an insertion-opening in the outer surface of the golf club head; a quick-release lid of the insertion-opening; a tubular part disposed in a hollow of the hollow structure and having a bottomed hole with which the insertion-opening communicates; and a gravity point adjuster. The gravity point adjuster comprises: a heavy-weight member having a specific gravity and a length L2; a light-weight member having a specific gravity less than that of the heavy-weight member and a length L1 more than the length L2; and an elastic member having a specific gravity less than that of the heavy-weight member, and an elastic modulus lower than those of the heavy-weight member and light-weight member. The heavy-weight member, light-weight member and elastic member are inserted in the bottomed hole by the use of the insertion-opening so that their relative positions relative to the bottomed hole can be changed easily by the golfer himself or herself.
