PROBLEM TO BE SOLVED: To provide a hose having no part where compression or tension force in the axial direction and pressure in the bending direction are locally concentrated, so that a crack is hardly formed or the hose is hardly broken even if the compression and tension force in the axial direction and the pressure in the bending direction are repeatedly applied to the hose while the hose is used, and capable of recovering itself naturally in a circular arc shape even if the hose is accidentally trodden. SOLUTION: The cleaner hose consists of a tube wall 1 formed as inner/outer double walls 2 of a thin film-like band material, a synthetic resin reinforcing wire 4 spirally disposed between the double walls 2, and a conductive line 3 inserted into the inside of the reinforcing wire 4. The reinforcing wire 4 is cylindrical, and the conductive line 3 consisting of an aggregate of thin lines is slackly inserted into the internal hollow c. The reinforcing wire 4 is also slackly inserted into the space S formed between the double walls 2 of the tube wall 1. COPYRIGHT: (C)2005,JPO&NCIPI
