<p>PROBLEM TO BE SOLVED: To prevent the generation or the like of an abnormal sound due to the projection and biting-in of a housed electric wire and slit rubbing by a simple rubber-material buffer zone integrally molded to a tube body in place of an adhesive tape without using the adhesive tape or the like in the opening closing works of a slit section, in a corrugated tube for protecting an electric- wire coating in which the slit section into which the electric wire and a wire harness are inserted is formed. SOLUTION: The buffer zones 15, 16 of a rubber material are molded simultaneously and formed at one-end side edge section, and the other-end side edge section of a groove forming a slit section 14 formed to the tube body 11 of a plastic molded form by a two-color molding method respectively. These buffer zones 15, 16 are closely attached elastically at all times by proper resiliency and the slit section 14 is brought to the closed state. The slit section 14 is brought the open state so as to push open the buffer zones 15, 16, and an electric wire and a wire harness are inserted and can be housed into the tube body 11.</p> |
