<br> The management cable of the present invention includes a conduit having flexibility, inside floor of which being fitted with a liner, and an inside cable having an internal coat, which is inserted into the conduit in order that the interior cable free slides in the conduit. As an illustration, in case the shortage of lubricants is generated due to the lengthy period use of the management cable, there are some issues that the liner is totally worn down and the operationability of the control cable is excessively lowered, and the like. In the present invention, for the reason that organopolysiloxane having an ultra-high viscosity and the organopolysiloxane having a decrease viscosity are dispersively contained within the thermoplastic resin used within the above-talked about liner, it's of course that there is no necessity to make use of a lubricant between the interspace of the conduit and the inner cable, and a superb function that the sliding operation of the conduit and the inner cable could be smoothly carried out for a long time frame, is exhibited. When the kinematic viscosity exceeds 10000 cSt, the organopolysiloxane does not bleed out from the thermoplastic resin sufficiently, and the load effectivity is lowered. When the kinematic viscosity is less than 25 cSt, the organopolysiloxane having a decrease viscosity is evaporated in a short time, and the wear and tear of the liner are generated through the management cable is used.<br>
<br> The article of the current invention is to delete the above-mentioned disadvantages of conventional management cables and to provide a control cable which does not necessitate a lubricant to keep away from a complex coating operation and which can be utilized with easy sliding operation of the internal cable for a protracted period of time. FIG. 1 is a partially-cut-off perspective view showing one embodiment of the management cable of the current invention. When the content of the organopolysiloxane is lower than 13% by weight, shield control cable the load effectivity is lowered when the management cable is used for a long time frame. The representative examples of the organopolysiloxane having a lower viscosity are, as an illustration, dimethylpolysiloxane, methylalkylpolysiloxane, methylphenylpolysiloxane, methylaminoalkylpolysiloxane, methylfluoroalkylpolysiloxane, and the like. The everyday examples are, as an example, dimethylpolysiloxane, methylalkylpolysiloxane, methylphenylpolysiloxane, methylaminoalkylpolysiloxane, methylfluoroalkylpolysiloxane, and the like. Representative examples of the kind II are, for example, Teflon (Registered Trademark) PFA 340-J commercially out there from DUPONT-MITSUI FLUORO CHEMICALS CO., LTD., and the like.<br>
<br> The management cable has been conventionally used in an effort to operate a transmission utilized in vehicles, autobicycles, bicycles and the like, a brake, a clutch, a speedmeter, and the like. FIG. 2 is an illustrative view of an apparatus for measuring the properties of the management cable of the current invention. When the melt index of the polybutylene terephthalate is lower than 0.1 g/10 minutes, it's troublesome to supply a liner via an extruder, and when the melt index exceeds 5 g/10 minutes, there is a tendency that the liner is easily peeled off from the conduit because of the lack of toughness of the liner during forming the liner and that bodily properties corresponding to sturdiness and abrasion resistance required for the liner should not simply exhibited. However, there are several issues, within the control cable through which a lubricant is used, akin to issue of operation for coating because dispersion of the load efficiency of products is attributable to 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.<br>
<br> However, when a organopolysiloxane having too low a viscosity is contained in a big amount within the resin, there is a problem that the organopolysiloxane can't be effectively extruded to provide a liner, and thus the molding can't be carried out due to the slipping of the resin on the cylinder barrel within the extruder. When the content is more 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. When the content material of the organopolysiloxane having an extremely-high viscosity is less that 45% by weight and the content 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 cannot be carried out. Out of the whole number of rods, 40 ones are used for vitality distribution management by means of the hight of the active zone of the reactor. However, when the viscosity of the organopolysiloxane is too excessive, the quantity of the organopolysiloxane which is extided from the floor of the resin is little, and according the load efficiency and sturdiness of the management cable cannot be improved sufficiently.<br>
