<p><P>PROBLEM TO BE SOLVED: To provide a golf club head, in which the position of the center of gravity can be changed largely by changing the position of a weight member having a larger specific gravity and light-weight member having a smaller gravity. <P>SOLUTION: The golf club head includes a tubular part 10 including an insertion-opening 12 opened on the outer surface 1A of the head and a bottomed recess 11 extending within a hollow i; and a gravity point adjuster 14 to be inserted into the recess 11 for adjusting the center of gravity of the head 1. The gravity point adjuster 14 includes the weight member 15 which has a length L2 along the axial direction of the recess 11 and whose specific gravity is large, and the light-weight member 16 whose specific gravity is smaller than that of the weight member 15 and which has a longer length L1 in the axial direction than the length L2. With respect to the positions of the two members 15 and 16, it is possible to change one for the other. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
