Further, it can be seen that the management cable produced in Example 5, by which organopolysiloxane was dispersively contained in thermoplastic resins of both the liner and the inside coat, has physical properties almost equal to the management cables produced in different Examples, wherein organopolysiloxane was dispersively contained only in the thermoplastic resin of the liner. The organopolysiloxane comprising the organopolysiloxane having an extremely-excessive viscosity and the organopolysiloxane having a lower viscosity is dispersively contained within the thermoplastic resin so that the content material of the organopolysiloxane is 13 to 20% by weight. As is evident from the outcomes shown in Tables 1 to 4, the management cables of the current invention produced in Examples are excellent in preliminary load effectivity and cargo effectivity after the operation was carried out 1,000,000 instances in comparison with the management 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 identical.

In FIG. 1, 1 denotes an internal cable, 2 denotes a conduit, 3 denotes an interior coat, and four denotes a liner. FIG. 1 is a partially-reduce-off perspective view exhibiting one embodiment of the pull sort control cable of the present invention. As talked about above, because the management cable of the current invention does not necessitate a lubricant, an issue regarding workability for coating a lubricant is solved and irregurality of load effectivity of products because of the uneveness of coating isn't generated. Among them, polyoxymethylene is preferably utilized in the current invention because 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 could 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, specifically, polytetrafluoroethylene are preferably used as a result of they are excellent in thermal resistance, load effectivity and suppleness.

Accordingly, when an interior coat is produced from the polytetrafluoroethylene, so-called a paste-extrusion methodology is employed. Examples of the thermoplastic resin are, as an illustration, polybutylene terephthalate, excessive density polyethylene, polyoxymethylene, a fluorocarbon resin represented by polytetrafluoroethylene, a polyamide represented by 6,6-nylon, polyphenylene sulfide, and the like, but the current invention will not be restricted by the exemplified ones. When the melt index of the high density polyethylene is lower than 0.01 g/10 minutes, the extrusion molding becomes tough, and there's a tendency that the internal coat can't be mounted on a stranded steel wire. The excessive density polyethylene has a density of a minimum of 0.95 g/cm.sup.3. It's preferable that the elastomer has an ability 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 a minimum of 5% (ASTM D 638). Representative examples of such an elastomer are, as an illustration, an olefin copolymer containing an epoxy group (ethylene content: 88% by weight, glycidyl methacrylate content material: 12% y weight), a hydrogenated styrenebutadience copolymer (TUFTEC M 1913 commercially available from Asahi Chemical Industry Co., Ltd.), an ethylene-propylene copolymer (TAFMER PO 680 commercially accessible from MITSUI PETRO CHEMICAL INDUSTRIES, LTD.), and the like.

Accordingly, it is preferable that the melt index is a minimum of 0.1 g/10 minutes. The smaller the melt index of the polybutylene terephthalate is, the better the durability similar to abrasion resistance and stress-cracking resistance is, but it surely tends to be troublesome 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 kind II is 6 to 7 instances larger than that of the type I, the type II is appropriate for uses necessitating sturdiness as a result of the sort II might be employed in an extrusion molding. Within the protective layer 6, varied materials conventionally known corresponding to polypropylene and polyvinyl chloride can be utilized. The outside of the armor 5 is coated with the protective layer 6 having a thickness of 0.7 mm. Next, the liner was inserted right into a conduit having a protective layer made of polypropylene of 0.7 mm in thickness on the skin surface of a springy armor layer having an outdoor diameter of 8.6 mm.
