PURPOSE:To reduce a stroke loss, by closely lining an armored layer of high rigidity between an inner tube and a coating layer and increasing the rigidity in an axial direction of the whole conduit. CONSTITUTION:An inner tube 3 provides in its periphery an armored layer 4 formed by spirally winding a wire rod 4a made of fiber reinforced resin so as to be brought into close contact with each other further in a coil-state along a lengthwise direction of the inner tube 3. The armored layer 4 forms on its periphery a synthetic resin made coating layer 5. the wire rod 4a constituting this armored layer 4 consists of synthetic resin reinforced by fiber. Accordingly, a control cable, providing high rigidity in the axial direction, reduces a stroke loss being a contractive margin of a conduit when tension is given to an inner cable under a predetermined condition. |
