<P>PROBLEM TO BE SOLVED: To provide a walking stick which has sufficient strength with an excellent impact resistance, excellent safety, excellent durability, excellent repairability and high rigidity, and is light in weight. <P>SOLUTION: The walking stick has a shaft portion (4) and a grip portion. The shaft portion (4) includes high-strength organic fiber-reinforced resin layers (31) and a carbon fiber-reinforced resin layer (32). The high-strength organic fiber-reinforced resin layers (31) are integrally piled up on the outer circumferential surface and the inner circumferential surface of the carbon fiber-reinforced resin layer (32). A further inside of the innermost high-strength organic fiber-reinforced resin layer (31a) includes a glass fiber-reinforced resin layer (33a). A further outside of the outermost high-strength organic fiber-reinforced resin layer (31b) includes a glass fiber-reinforced resin layer (33b). <P>COPYRIGHT: (C)2012,JPO&INPIT |
