PROBLEM TO BE SOLVED: To prevent the exposure, etc., of knitting and braiding of metallic wires and the dislodgment of a front end tube consisting of a UV curing resin compsn. having no knitting and braiding and to improve quality and reliability by connecting a torque transmission part provided with the knitting and braiding of the metallic wires between the inner and outer layers consisting of a UV curing resin compsn. and the front end tube on the same axis. SOLUTION: The torque transmission part 6 is constituted by applying the knitting and braiding 4 of the metallic wires on the outer periphery of the inner layer tube consisting of the UV curing resin compsn. and forming the outer layer tube 5 consisting of the UV curing resin compsn. on its outer periphery. The front end tube 7 is formed of the UV curing resin compsn. to the same diameter as the diameter of the inner layer tube 3 without including the knitting and braiding. The torque transmission part 6 and the front end tube 7 are set in a mold 8 and the UV curing resin compsn. is poured into the mold from a resin injecting part 9 and is cured to connect both 6, 7. For example, a urethane acrylate based UV curing resin compsn., etc., are used as the UV curing resin compsn. |
