Claims

[Scope of Claim for Utility Model Registration] 1. A shaft for a golf club made of fiber-reinforced resin, which is formed by winding and laminating a prepreg in which reinforcing fibers are impregnated with a synthetic resin around a core metal for shaft molding and molding the shaft into a tapered shape. 1. A shaft for a golf club made of fiber-reinforced resin, characterized in that the reinforcing fibers of the bias layer to be formed are composed of two or more types of fibers having partially different elastic moduli or strengths in the longitudinal direction of the shaft. 2. In a golf club shaft made of fiber-reinforced resin, in which a prepreg in which reinforcing fibers are impregnated with a synthetic resin is wound and laminated around a core metal for shaft molding and formed into a tapered shape, the reinforcing fibers of the bias layer forming the shaft are A shaft for a golf club made of a fiber-reinforced resin, characterized in that the basis weight is partially different in the length direction of the shaft. 3. In a golf club shaft made of fiber-reinforced resin, in which a prepreg in which reinforcing fibers are impregnated with a synthetic resin is wound and laminated around a core metal for shaft molding and formed into a tapered shape, the reinforcing fibers of the bias layer forming the shaft are A shaft for a golf club made of fiber-reinforced resin, characterized in that the amount of resin impregnated is partially different in the length direction of the shaft.
