The conduit comprises, as an illustration, a coiled spring produced by winding one or plural flat steel wires or spherical steel wires in abutting convolutions and an outer coat product of a synthetic resin which covers the skin surface of the coiled spring. The inner cable often comprises a stranded wire produced by twisting plural metallic wires or a stranded wire of which surroundings are coated with a artificial resin or strengthened by twisting flat steel wires across the stranded wire. Also, a artificial resin coating (hereinafter referred to as inner coat) is set on the outer surroundings of the interior cable. When the content material of the organopolysiloxane is less than 13% by weight, the load efficiency is lowered when the control cable is used for an extended time frame. As an example, in case the scarcity of lubricants is generated because of the long interval use of the control cable, there are some issues that the liner is completely worn down and the operationability of the management cable is excessively lowered, and the like. However, there are a number of problems, in the management cable during which a lubricant is used, comparable to issue of operation for coating because dispersion of the load effectivity of merchandise is brought on by the unevenness of a coating, rubbishes and dusts are easily adhered to the lubricant when making use of the lubricant to the control cable, and drip and the like are generated.

When the kinematic viscosity is lower than 25 cSt, the organopolysiloxane having a lower viscosity is evaporated in a short time, and the put on and tear of the liner are generated during the management cable is used. When the content material of the organopolysiloxane having an extremely-high viscosity is more than 85% by weight and the content material of the organopolysiloxane having a decrease viscosity is much less that 15% by weight, the results don't differ a lot from the consequences when the organopolysiloxane having an extremely-high viscosity is used solely, and the development of load effectivity is little. When the content material of the organopolysiloxane having an extremely-high viscosity is less that 45% by weight and the content material of the organopolysiloxane having a decrease viscosity is extra that 55% by weight, an extruded product cannot be produced as a result of a slide between a screw and a resin happens in an extruder and the feed of the resin can't be carried out.

When the content is extra that 20% by weight, an extruded product cannot be produced because a slip of a resin occurs on a cylinder barrel in an extruder and the fixed feed of the resin can't be carried out. However, when a organopolysiloxane having too low a viscosity is contained in a big amount within the resin, there may be a problem that the organopolysiloxane cannot be successfully extruded to supply a liner, and thus the molding can't be carried out due to the slipping of the resin on the cylinder barrel in the extruder. As an illustration, a method comprising ading the organopolysiloxane having an extremely-high viscosity and the organopolysiloxane having a decrease viscosity separately to the thermoplastic resin while heating and kneading the thermoplastic resin and uniformly dispersing them, a way comprising adding the organopolysiloxane, which is previously ready by mixing the organopolysiloxane having an extremely-excessive viscosity and the organopolysiloxane having a lower viscosity in a prescribed proportion, to the melted thermoplastic resin and uniformly dispersing them, and the like can be exemplified. As a method for forming an interior coat by using the polyphenylene sulfide, as an illustration, a melt-extrusion methodology and an electrostatic coating method of powder could be cited.

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 is just not limited by the exemplified ones. The control cable has been conventionally used with the intention to function a transmission used in vehicles, autobicycles, bicycles and the like, a brake, a clutch, a speedmeter, and the like. Examples of the thermoplastic resin used in the above-mentioned liner are, for example, polybutylene terephthalate, polyoxymethylene, polyamide represented by 1-nylon and 6,6-nylon, and the like, however the current invention is just not restricted to the exemplified ones and other thermoplastic resins can be used so far as the object of the present invention could be completed. Examples of the above-talked about polybutylene terephthalate are, for instance, a homopolymer of butylene terephthalate, a copolymer of butylene terephthalate and other monomer such as ethylene terephthalate having a content of the opposite monomer of at most about 10% by weight, and the like. The standard examples are, as an example, dimethylpolysiloxane, methylalkylpolysiloxane, methylphenylpolysiloxane, methylaminoalkylpolysiloxane, methylfluoroalkylpolysiloxane, and the like. The representative examples of the organopolysiloxane having a lower viscosity are, as an illustration, dimethylpolysiloxane, methylalkylpolysiloxane, methylphenylpolysiloxane, methylaminoalkylpolysiloxane, methylfluoroalkylpolysiloxane, and the like.
