しい。The cable conduit of this embodiment has a structure in which a corrugated inner pipe 2 is accommodated in a corrugated outer pipe 1. The corrugated outer tube 1 is formed of a hard material which is not easily damaged, such as high density polyethylene (HDPE) or polyvinyl chloride (PVC). Thus, even if the corrugated outer tube 1 is formed of a hard material, it is corrugated, so that the necessary flexibility can be sufficiently obtained. Since the corrugated inner tube 2 is in the corrugated outer tube 1 and is corrugated, any material may be used. However, in this case, it is desirable that the pitch A of the corrugated inner tube 2 and the pitch B of the corrugated outer tube 1 be B ≧ 2A. The reason for this is to improve the flexibility and the pull-in property by preventing the uneven portions formed by corrugation from meshing with each other. The inner diameter of the corrugated inner tube 2 depends on the outer diameter of a cable or the like inserted into the corrugated inner tube 2 and the corrugated outer tube 1, but is about 1/3 or less of the inner diameter of the corrugated outer tube 1. Is preferred.

易に行うことができる。When the corrugated inner tube 2 and the corrugated outer tube 1 are corrugated so that the wave peaks facing each other intersect at a portion where they are in contact with each other, the wave peak of the corrugated inner tube 2 is formed. The corrugated inner pipe 2 can be drawn in more easily without falling into the wave trough on the inner surface of the corrugated outer pipe 1.
【００１３】波付外管１内における波付内管２の本数
