Patent ID: 6857972

Claim:
A golf club shaft comprising: an intermediate-elasticity and high-strength carbon fiber reinforced resinous sheet having a tensile modulus of elasticity of 30 ton/mm 2 to 33 ton/mm 2 and a tensile strength of not less than 5000 MPa; and a low-elasticity carbon fiber reinforced resinous sheet having a tensile modulus of elasticity of 5 ton/mm 2 to 10 ton/mm 2 and compressive breaking strain of not less than 2.0%, each of said intermediate-elasticity and high-strength carbon fiber reinforced resinous sheet and said low-elasticity carbon fiber reinforced resinous sheet being used to reinforce a tip side of said golf club shaft, wherein each of said intermediate-elasticity and high-strength carbon fiber reinforced resinous sheet and said low-elasticity carbon fiber reinforced resinous sheet is disposed from said tip to a position located at not more than 20% of an overall length of said golf club shaft.
