Further, it may be seen that the control cable produced in Example 5, through which organopolysiloxane was dispersively contained in thermoplastic resins of each the liner and the interior coat, has bodily properties virtually equal to the management cables produced in other Examples, during which organopolysiloxane was dispersively contained only in the thermoplastic resin of the liner. The organopolysiloxane comprising the organopolysiloxane having an ultra-high viscosity and the organopolysiloxane having a lower viscosity is dispersively contained in the thermoplastic resin so that the content material of the organopolysiloxane is 13 to 20% by weight. As is obvious from the outcomes proven in Tables 1 to 4, the control cables of the current invention produced in Examples are glorious in initial load effectivity and load efficiency after the operation was carried out 1,000,000 instances as compared with the control cables produced in Comparative Examples when both the type of the thermoplastic resin used in the liner in Examples and that in Comparative Examples are the same.

In FIG. 1, 1 denotes an inside cable, 2 denotes a conduit, three denotes an interior coat, and four denotes a liner. FIG. 1 is a partially-lower-off perspective view showing one embodiment of the pull type control cable of the current invention. As mentioned above, because the management cable of the present invention doesn't necessitate a lubricant, a problem regarding workability for coating a lubricant is solved and irregurality of load efficiency of products due to the uneveness of coating is just not generated. Among them, polyoxymethylene is ideally utilized in the current invention as a result of a stickslip is hardly generated when polyoxymethylene is used. The polyphenylene-sulfide is divided broadly into two groups of a crosslinked prepolymer and a linear prepolymer, and these might be utilized in the present invention. The tetrafluoroethylene-perfluoroalkylvinyl ether copolymer is prescribed in ASTM D 3307, and has two sorts, i.e. Type I and sort II. Among them, polytetrafluoroethylene, tetrafluoroethyleneperfluoroalkylvinyl ether copolymer and tetrafluoroethylene-hexafluoroethylene copolymer, in particular, polytetrafluoroethylene are ideally used because they are wonderful in thermal resistance, load efficiency and suppleness.

Accordingly, when an internal coat is produced from the polytetrafluoroethylene, so-referred to as a paste-extrusion method is employed. Examples of the thermoplastic resin are, for example, polybutylene terephthalate, excessive density polyethylene, polyoxymethylene, a fluorocarbon resin represented by polytetrafluoroethylene, a polyamide represented by 6,6-nylon, polyphenylene sulfide, and the like, however the current invention will not be limited by the exemplified ones. When the melt index of the excessive density polyethylene is lower than 0.01 g/10 minutes, the extrusion molding becomes difficult, and there is a tendency that the internal coat can't be fixed on a stranded steel wire. The excessive density polyethylene has a density of at the least 0.Ninety five g/cm.sup.3. It is preferable that the elastomer has an means to be modified so that a softened polyphenylene sulfide, which is ready by mixing with the elastomer and kneading them with melting, has a flexural modulus of at most 30000 (ASTM D 790) and a tensile elongation at break of at the very least 5% (ASTM D 638). Representative examples of such an elastomer are, as an example, an olefin copolymer containing an epoxy group (ethylene content material: 88% by weight, glycidyl methacrylate content material: 12% y weight), a hydrogenated styrenebutadience copolymer (TUFTEC M 1913 commercially accessible from Asahi Chemical Industry Co., Ltd.), an ethylene-propylene copolymer (TAFMER PO 680 commercially available from MITSUI PETRO CHEMICAL INDUSTRIES, LTD.), and the like.

Accordingly, it is preferable that the melt index is no less than 0.1 g/10 minutes. The smaller the melt index of the polybutylene terephthalate is, the larger the sturdiness similar to abrasion resistance and stress-cracking resistance is, however it tends to be difficult for carrying out the extrusion molding. Accordingly, it is preferable that the melt index is 0.5 to 5 g/10 minutes. Although melt viscosity of the type II is 6 to 7 times better than that of the type I, the kind II is appropriate for uses necessitating sturdiness because the kind II could be employed in an extrusion molding. In the protective layer 6, various materials conventionally known comparable to polypropylene and polyvinyl chloride can be utilized. The outside of the armor 5 is lined with the protecting layer 6 having a thickness of 0.7 mm. Next, the liner was inserted right into a conduit having a protective layer fabricated from polypropylene of 0.7 mm in thickness on the outside floor of a springy armor layer having an outdoor diameter of 8.6 mm.
