<p><P>PROBLEM TO BE SOLVED: To solve the problem that a bend and torsion of a head caused by a bend and torsion of a shaft at a shot renders maintaining stability at the shot hard (a), that generating a bend and torsion of the shaft at the shot renders maintaining stability at the shot hard (b), and that increasing a head speed and a shot power renders a carry increased (c). <P>SOLUTION: In a first form of the embodiment, weights (14) are fixed on the middle part of the shaft (12). The weights (14) divided into two pieces are fixed on the shaft (12) and near the head (11) of the shaft (12) by two weight fixing bolts, wherein a material of the weights (14) is either of metal, rubber, fiber-reinforced plastic and plastic. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
