PROBLEM TO BE SOLVED: To facilitate manufacturing and installation work, to expand usage and to improve wear resistance, water-tightness and chemical resistance by winding a carbon fiber tape having a specific layer thickness around a cable sheath and by covering the outer layer of the carbon fiber tape with a polyacetal resin having a specific layer thickness. SOLUTION: Preferably, the layer thickness of a carbon fiber tape is set to 10 μm and the layer thickness of a polyacetal resin is set to 0.5-1.0 mm. This rat-proofing cable 11 is composed by winding the carbon fiber tape 13 around a cable sheath 12 and by covering the outer layer of the carbon fiber tape 13 with the polyacetal resin 14. Thereby, the Shore D hardness of the outer layer of the cable is set to approximately 50-65 so that the outer layer of the cable becomes relatively hard. The Shore D hardness of the inner layer of the cable is set to approximately 60-70 so that the inner layer of the cable becomes relatively hard and the cable excellent in a rat-proofing property can be provided, and when the inner and outer layers are thus combined, flexibility is also excellent. |
