ABSTRACT:
It is a sport equipment2using a partially hardened sheet form prepreg10formed by impregnating a reinforced fiber material6disposed substantially parallel with a thermal hardening resin material7to bind the reinforced fiber material, where the prepreg is layered so as to form a tube rod in a tapered shape having a diameter increasing from one end to the other, and the tube rod is provided with a strengthening means on a radially entire circumference to the axis direction. Herewith it is especially used for a golf club shaft, while maintaining a characteristic of light weight, securing strength equal to or greater than a steel-made golf shaft, and suppressing unnecessary deflection and vibration, so as to provide a sports equipment made of a reinforced fiber combined material such as a gold club shaft having high strength such as bending and twisting rigidity.
