PROBLEM TO BE SOLVED: To provide a flexible tube which is excellent in electrical insulation and seal performance.SOLUTION: A flexible tube 1 has a waveform tube 12 which is formed by alternately continuously connecting a large-diameter crest part 16 and a small-diameter trough part 18. At least one end part of the waveform tube has a rigid ring 22 which is fit to the trough part of the waveform tube, and one crest part 16a or one trough part which is left at the outside of the trough part 18a to which the rigid ring is fit with respect to a center axial direction of the waveform tube. A deformable ring 52 can be fit to one crest part or one trough part which is left at the outside of the trough part to which the rigid ring is fit.SELECTED DRAWING: Figure 2 |
