<P>PROBLEM TO BE SOLVED: To provide a shaft set for golf clubs capable of reducing variation in manufacturing precision by simplifying a lamination structure when adjusting flexural rigidity. <P>SOLUTION: A shaft 12 of each number includes: the front section FS formed by winding prepregs 42, 44, 46 around the front section of a metallic core 20; the back section BS formed by winding prepregs 52, 54, 56 around the back section of the metallic core; and an middle section MS that is along the middle section of the metallic core, and is formed between the front and back sections by winding prepregs 62, 64, 66 at outer peripheries of the front and back sections. The front and back sections have the same or a larger flexural rigidity as the golf club number increases, and the middle section has the same flexural rigidity in each number. <P>COPYRIGHT: (C)2012,JPO&INPIT |
