<p><P>PROBLEM TO BE SOLVED: To provide a golf club which can replace a shaft and the characteristic of the golf club can be accurately determined by test-hitting a ball. <P>SOLUTION: A hozel sleeve 10 is fittingly fixed inside the hole of the hosel h of a head H in a concentric manner with the hole of the hozel h and a female screw 14 is installed integrally with an inner end section of the hozel sleeve 10. A shaft sleeve 2 is fittingly fixed on the tip end of a shaft S and a male screw 3 is installed integrally at the end of the shaft sleeve 2 in a concentric manner with the shaft sleeve 2. The shaft sleeve 2 at the end of the shaft S is fittingly inserted inside the hozel sleeve 10 and the male screw 3 at the end of the shaft sleeve 2 is screwed into the female screw 14 at the inner end section of the hozel sleeve 10, by which the shaft S is fixed inside the hozel h. The shaft S is removed by a reverse procedure. The male and female correlation can be the other way round. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
