The representative examples of the **anopolysiloxane having a decrease viscosity are, for instance, dimethylpolysiloxane, methylalkylpolysiloxane, methylphenylpolysiloxane, methylaminoalkylpolysiloxane, methylfluoroalkylpolysiloxane, and the like. Examples of the above-mentioned polybutyle**erephthalate are, for example, a homopolymer of butyle**erephthalate, a copolymer of butyle**erephthalate and different monomer similar to ethyle**erephthalate having a co** of the opposite monomer of at most about 10% by weight, and the like. Examples of the thermoplastic resin are, for example, polybutyle**erephthalate, excessive density polyethylene, polyoxymethylene, a fluorocarbon resin represented by polytetrafluoroethylene, a polyamide represented by 6,6-nylon, polyphenylene sulfide, and the like, but the present i**ion is not limited by the exemplified ones. Examples of the thermoplastic resin used in the above-talked about liner are, as an example, polybutyle**erephthalate, polyoxymethylene, polyamide represented by 1-nylon and 6,6-nylon, and the like, however the present i**ion isn't restricted to the exemplified ones and different thermoplastic resins ** be utilized as far as the thing of the current i**ion may be **pleted. Also, when the melt index is too massive, the polybutyle**erephthalate lacks toughness and cracks are generated within the interior coat, and the liner is often damaged when the internal coat is quickly bent in the assembling process of a management cable.

Also, a artificial resin coating (hereinafter known as inside coat) is set on the outer surroundings of the inside cable. As a cloth used in the liner, as an illustration, a synthetic resin **parable to polyethylene, polyoxymethylene, polybutyle**erephthalate or polytetrafluoroethylene is used. When the melt index of the polybutyle**erephthalate is less than 0.1 g/10 minutes, it is tough to produce a liner by the use of a**ruder, and when the melt index exceeds 5 g/10 minutes, there's a tendency that the liner is easily peeled off from the **duit because of the lack of toughness of the liner throughout forming the liner and that physical properties corresponding to sturdiness and abrasion resistance required for the liner are not easily exhibited. The polybutyle**erephthalate is excellent in thermal resistance, oil resistance and abrasion resistance, and has a low coefficient of friction. Also, the above-talked about polybutyle**erephthalate might **prise a polymer reminis**t of polyester or polyether-ester inside a scope that the thing of the present i**ion isn't inhibited in the present i**ion.

Also, the sturdiness of the above-talked about management cable largely depends upon the lubri**t. Also, the **anopolysiloxane ** be prepared to grease. It's preferable that the **anopolysiloxane has a low viscosity in order that the **anopolysiloxane ** simply extide from the resin. However, when a **anopolysiloxane having too low a viscosity is **tained in a big amount in the resin, there's a problem that the **anopolysiloxane **not be effectively extruded to supply a liner, and thus the molding **not be carried out because of the slipping of the resin on the cylinder barrel within the extruder. In the above-talked about liner, a thermoplastic resin **taining 13 to 20% by weight of an dispersed within the resin, is used. As to a method for **taining the **anopolysiloxane within the thermoplastic resin, there is no such thing as a limitation. Then again, a large amount of the **anopolysiloxane having a high viscosity might be **tained in the resin, and the molding may be carried out with out slipping. The smaller the melt index of the polybutyle**erephthalate is, the larger the durability such as abrasion resistance and stress-cracking resistance is, but it surely tends to be tough for finishing up the extrusion molding.

However, in such a management cable, frictional resistance increases when the **duit is directly **tacted with the inner cable. So as to enha**he load effectivity of a management cable with out a lubri**t, an **anopolysiloxane is **tained in a res**r a liner or an interior coat, and the **anopolysiloxane extides from on the floor of the resin. When the kinematic viscosity exceeds 10000 cSt, the **anopolysiloxane does not bleed out from the thermoplastic resin sufficiently, and the load efficiency is lowered. When the kinematic viscosity is less than 25 cSt, the **anopolysiloxane having a lower viscosity is evaporated in a short while, and the wear and tear of the liner are generated throughout the management cable is used. As the above-talked about **anopolysiloxane having a**remely-excessive viscosity, a linear **anopolysiloxane, a branched **anopolysiloxane and the like might be exemplified. For example, a way **prising ading the **anopolysiloxane having a**remely-high viscosity and the **anopolysiloxane having a lower viscosity individually to the thermoplastic resin while heating and kneading the thermoplastic resin and uniformly dispersing them, a method **prising including the **anopolysiloxane, which is previously prepared by mixing the **anopolysiloxane having an ultra-excessive viscosity and the **anopolysiloxane having a lower viscosity in a prescribed proportion, to the melted thermoplastic resin and uniformly dispersing them, and the like ** be exemplified.
