Further, it may be seen that the control cable produced in Example 5, during which organopolysiloxane was dispersively contained in thermoplastic resins of each the liner and the interior coat, has physical properties nearly equal to the control cables produced in different Examples, wherein organopolysiloxane was dispersively contained only within the thermoplastic resin of the liner. The organopolysiloxane comprising the organopolysiloxane having an extremely-high viscosity and the organopolysiloxane having a decrease viscosity is dispersively contained in the thermoplastic resin so that the content material of the organopolysiloxane is thirteen to 20% by weight. As is obvious from the outcomes proven in Tables 1 to 4, the management cables of the current invention produced in Examples are excellent in preliminary load efficiency and cargo effectivity after the operation was carried out 1,000,000 instances compared with the control cables produced in Comparative Examples when both the kind of the thermoplastic resin used within the liner in Examples and that in Comparative Examples are the identical.

In FIG. 1, 1 denotes an internal cable, 2 denotes a conduit, three denotes an internal coat, and four denotes a liner. FIG. 1 is a partially-lower-off perspective view exhibiting one embodiment of the pull kind 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 concerning workability for coating a lubricant is solved and irregurality of load efficiency of merchandise as a result of uneveness of coating just isn't generated. Among them, polyoxymethylene is preferably utilized in the present invention as a result of a stickslip is hardly generated when polyoxymethylene is used. The polyphenylene-sulfide is divided broadly into two teams of a crosslinked prepolymer and a linear prepolymer, and these will 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, particularly, polytetrafluoroethylene are ideally used as a result of they're excellent in thermal resistance, load effectivity and flexibility.

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 example, polybutylene terephthalate, high density polyethylene, polyoxymethylene, a fluorocarbon resin represented by polytetrafluoroethylene, a polyamide represented by 6,6-nylon, polyphenylene sulfide, and the like, however the present invention is just not 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 turns into tough, and there is a tendency that the inner coat cannot be fixed on a stranded steel wire. The high density polyethylene has a density of no less than 0.Ninety five g/cm.sup.3. It's preferable that the elastomer has an potential to be modified so that a softened polyphenylene sulfide, which is prepared 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 no less than 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 obtainable from MITSUI PETRO CHEMICAL INDUSTRIES, LTD.), and the like.

Accordingly, it is preferable that the melt index is not less than 0.1 g/10 minutes. The smaller the melt index of the polybutylene terephthalate is, the higher the durability equivalent to abrasion resistance and stress-cracking resistance is, but it tends to be tough 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 times higher than that of the sort I, the type II is appropriate for makes use of necessitating durability because the type II may be employed in an extrusion molding. In the protective layer 6, varied materials conventionally known such as polypropylene and polyvinyl chloride can be utilized. The surface of the armor 5 is lined with the protecting layer 6 having a thickness of 0.7 mm. Next, the liner was inserted into a conduit having a protecting layer fabricated from polypropylene of 0.7 mm in thickness on the surface floor of a springy armor layer having an outdoor diameter of 8.6 mm.
