<p><P>PROBLEM TO BE SOLVED: To provide a putter head which permits the adjustment of anteroposterior weight balance or the anteroposterior weight balance and crosswise weight balance. <P>SOLUTION: The putter head 1 has two bottomed holes 12 heading to a face surface 6 from the rear 7 are provided on the rear 7 of a head body 2 whose front is a face 6. The bottomed holes 12 are formed so as to removably store five nested weights 16 made of steel balls, the specific gravity of which is greater than the head body 2 made of an aluminum alloy, and coil springs 17. With the bottomed holes 12 storing the nested weights 16 and the coil springs 17 covered with lid members 15, the nested weights 16 are pressure contacted to and supported on deep bottoms 14 in the bottomed holes 12 or the lid members 15 by the resilient force of the coil springs 17. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
