PURPOSE:To enhance anti-abrasiveness and heat resistance by installing a liner, which consists of thermo-plastic resin manufactured by two-axis extending method, between a conduit with flexibility and an inner cable set in this conduit with possibility of sliding. CONSTITUTION:An inner cable 2 formed by twisting a plurality of metal wires is set slidably in a flexible conduit 1 formed by winding a flat steel wire spirally. Between the conduit 1 and inner cable 2, a liner 3 is provided which consists of thermo-plastic resin manufactured by two-axis extending method. An example of such resin used to the liner 3 is polyethylene teleftarate manufactured by two-axis extending method. This will provide the liner 3 with a greatly enhanced anti-abrasiveness and heat resistance, which allows use of a cable for a longer period of time.
