CABLE PROTECTING TUBE AND CABLE LAYING STRUCTURE

PROBLEM TO BE SOLVED: To provide a cable protecting tube and a cable laying structure by which a branching direction of a cable is not restricted. SOLUTION: The cable protecting tube 10 is formed by a double tube in which an inner tube 12 is inserted into an outer tube 14, and supporting members 16 are provided in the outer tube 14 with intervals in an axial direction. The supporting members 16 include fixing portions 26, supporting portions 28, and joints 30, the supporting portions 28 which support the inner tube 12 are arranged at the center of the outer tube 14, and the fixing portions 26 and the joints 30 are arranged at an upper portion of the outer tube 14. A first cable is inserted into the inner tube 12, and the second cable is inserted between the inner tube 12 and the outer tube 14. With such constitution, flaws of the second cable are prevented when the second cable is pulled in, and friction produced by the cable protecting tube 10 is reduced. Moreover, when the second cable is branched, if the direction of the second cable is changed by ring type space between each supporting member 16, or space 34 of a lower part of the supporting members 16, the branching direction of the second cable is not restricted.
