Abstract:
1. A combination of a golf club head and a gravity point adjuster, wherein the 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, and a tubular part disposed in a hollow of the hollow structure and having a bottomed hole with which the insertion-opening communicates, and the gravity point adjuster comprises a heavy-weight member having a specific gravity and a length L a light-weight member having a specific gravity less than that of the heavy-weight member and a length L 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, wherein the 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 and wherein a wall of the tubular part partitioning between the bottomed hole and the hollow is provided with one or more through-holes, and a wall of the tubular part partitioning between the bottomed hole and the hollow is provided with one or more through-holes.
