摘要： PROBLEM TO BE SOLVED: To provide a cable that facilitates drawing out a desired cable out of multiple cables installed. SOLUTION: Cross-sectionally triangular protrusions 3 are successively so formed on the surface of a cable sheathing 2 installed around a cable core 1 as to surround its periphery. With this cable, when one cable is required to be drawn out for the purpose of removal or the like from multiple cables that are in tight contact with one another, the cable can be easily drawn out, because the cable is in contact with the adjacent cables at the apexes of the protrusions 3, and thereby is nearly in point contact with the other cables and has low friction resistance.

摘要： PROBLEM TO BE SOLVED: To provide an optical fiber cable closure with which the extra length segments of coated optical fibers are hardly movable in a tray. SOLUTION: This optical fiber cable closure has at least one tray 20 which has a spacer 34 having slots 36 on its outer periphery and a sheath 32 covering the spacer 34 and houses the extra length segments of the coated optical fibers 38 extending from the end of the optical fiber cable 2a disposed with the coated optical fibers 38 within the slits 36, a sleeve 10 which encloses the tray 20 and a supporting member 15 which fixes the optical fiber cable 2a to the sleeve 10. Further, the optical fiber cable closure has a region where the coated optical fibers 38 disposed in the slits 36 of the optical fiber cable 2a are exposed in the space from the supporting member 15 to the housing tray 20. A movement suppressing member 42 having compressibility is mounted at the outer periphery of the region where the coated optical fibers 38 are exposed. The coated optical fibers 38 are pressed to the spacer 34 within the slits 36 by the movement suppressing member 42.

摘要： PROBLEM TO BE SOLVED: To obtain a tip guide by which a linear body, such as a rod or the like can be smoothly and surely pushed into or pulled into an existing underground pipe after a cable has been pulled into by a method, wherein an outside roller group and an inside roller group which are composed respectively of a plurality of guide rollers are installed on a first carriage and a second carriage. SOLUTION: A first carriage 1 and a second carriage 2 are composed respectively of base parts 3, of intermediate parts 4 and of tip parts 5. Outside roller groups 7, composed of a plurality of guide rollers 6 capable of being turned along the long direction with respect to the inside of a conduit are installed at the base end parts 3, and inside roller groups 9 which are composed of a plurality of guide roller 8 capable of being turned along the long direction with respect to a cable of the conduit are installed at the intermediate parts 4 or the tip parts 5. As a result, a linear body such as a rod or the like can be smoothly and surely pushed into or pulled into an existing underground pipe (conduit) after the cable has been pulled into, so that the cable is not damaged externally.
