Claims

[Claims for Utility Model Registration] Inner pipe wall B made of soft synthetic resin material
and is wound spirally on the outer peripheral surface of the inner tube wall B.
An outer tube wall consisting of a reinforcing wire C fixed to the inner tube wall B, and a hard material strip 1 wound spirally on the outer peripheral surface of the inner tube wall B and fixed to the inner tube wall B. A, in which the cross-sectional shape of the hard strip material 1 is formed in a horizontally oriented substantially S-shape, and only the lower surface of the bottom portion 2 in the lateral orientation is exposed to the inner tube wall B. A free end 4 which is abutted and fixed on the outer peripheral surface and is bent from the end 3 on the bottom side 2 side and a free end 7 which is bent from the end on the other top side 5 side, and the free end 7 is bent from the end 3 on the bottom side 2 side. The reinforcing wire material C is arranged in a position that engages with each other in the axial direction and the radial direction, and furthermore, the reinforcing wire material C is arranged in a part other than the abutting and fixing part of the hard strip material 1 against the inner tube wall B. A flexible rigid tube with a fixed structure. 5. The flexible rigid tube according to claim 1, wherein the soft synthetic resin material forming the inner tube wall B is made of a polyolefin-based or vinyl chloride-based synthetic resin material.
