<p><P>PROBLEM TO BE SOLVED: To improve the connection strength of a head body and a weight member. <P>SOLUTION: In the golf club head 1 of a hollow shape, the weight member 1b composed of a material whose specific gravity is larger than the head body 1a is fixed to the head body 1a. At a weight attaching part to attach the weight member on the head body 1a, a cylindrical receiving part 7 projected to a head inner side and provided with a through-hole 8 opened at both ends is integrally formed. The weight member 1b is composed of a plastically deformable plastic material provided with a weight body 10 capable of being housed inside the through-hole 8, whose cross section is roughly the same shape as the through-hole 8, and a projected collapsing part 11 formed on an inner end face 12 forming the head inner side of the weight body 10. By arranging at least the outer surface F of the head body 1a and the outer end face 15 of the weight member 1b and deforming the side of the inner end face 12 of the weight body 10 in a trumpet shape by crushing the collapsing part 11 of the weight member 1b inserted to the through-hole 8, the weight member 1b is fixed to the receiving part 7. <P>COPYRIGHT: (C)2004,JPO</p> |
