Abstract:
A metal foil satisfies following conditional equations (1), (2) and (3) to smoothly increase rigidity in the longitudinal direction of the shaft main body from a distal end side to a base end side while increasing a weight of a wound part of the metal foil 0.50< Lmf/Ls    (1) Lmr/Ls <0.90   (2) 0.03< Wm/Ws <0.09   (3) where Lmf: a length from a distal end position in the longitudinal direction of the shaft main body to a winding start position of the metal foil, Lmr: a length from the distal end position in the longitudinal direction of the shaft main body to a winding end position of the metal foil, Ls: a length of the shaft main body, Wm: a weight of the metal foil, and Ws: a weight of the shaft main body.

Claim (Index 1):
A golf club shaft comprising a shaft main body formed by winding and thermally curing a prepreg made by impregnating reinforced fibers with a thermosetting resin, wherein\n a metal foil is located at and wound around a part in a longitudinal direction of the shaft main body, and the metal foil satisfies following conditional equations (1), (2) and (3) to smoothly increase rigidity in the longitudinal direction of the shaft main body from a distal end side to a base end side while increasing a weight of the wound part of the metal foil\n 0.50 <Lmf/Ls  \u2003\u2003(1) \n Lmr/Ls <0.90 \u2003\u2003(2) \n 0.03 <Wm/Ws  <0.09 \u2003\u2003(3) \n where Lmf: a length from a distal end position in the longitudinal direction of the shaft main body to a winding start position of the metal foil, Lmr: a length from the distal end position in the longitudinal direction of the shaft main body to a winding end position of the metal foil, Ls: a length of the shaft main body, Wm: a weight of the metal foil, and Ws: a weight of the shaft main body.
