PROBLEM TO BE SOLVED: To provide a push/pull controlling cable which can highly keep loading efficiency and durability for a long time. SOLUTION: An inner cable 20 passed into a liner 11 of a conduit 10 is prepared by winding a plurality of strands around an outer periphery of a core wire 21, each strand is prepared by normally twisting three element wires 22a. Grease G is charged between an inner peripheral surface of the conduit 10 and an outer peripheral surface of the inner cable 20. Instead of the inner cable 20, the following cables may be used. One is prepared by alternately winding a first large diameter strand formed by twisting three large diameter element wires, and a second small diameter strand formed by twisting three small diameter element wires, around the outer periphery of the core wire. The other is prepared by alternately winding a first strand formed by normally twisting three element wires, and a second strand formed by Lang lay of three element wires, around on the outer periphery of the core wire. |
