ことができる。As described above, in the electric wire protective cover according to the present invention, since the bellows type cylindrical body is composed of a combination of large and small diameters, the ends of the different diameter cylindrical bodies are mutually connected. The electric wire protection cover can be securely connected only by polymerizing. For this reason, it is not necessary to cut the cylindrical body to adjust the length according to the use conditions, and by adjusting the degree of polymerization of the overlapped portion of the end portion formed with different diameters of the wire protection cover, the length can be freely adjusted. The total length of the wire protection cover can be adjusted. Therefore, the electric wire having a desired length can be covered without requiring a complicated structure such as providing fitting flanges at both ends of the cylindrical body or fixing a joint pipe. Further, the electric wire protective cover of the present invention does not undergo cutting or the like during use, and thus can be repeatedly reused.
