ファイバーが在中しているので次のような特徴がある。The present invention will be described in detail. FIGS. 1 and 2 are shape diagrams of one embodiment of the present invention. Reference numeral 1 denotes an optical fiber inserted into the metal tube 2. 27) The thickness of the metal tube is extremely thin in the embodiment, for example, about 0.1 mm. The material used is stainless steel, with optical fibers encased in it, drawn repeatedly with dies, rollers, etc., to a minute diameter, and then appropriately annealed to make it flexible, as shown in Figure 2. Rope 21 is made by threading together two or more ropes as shown in the figure. Since this rope contains optical fibers, it has the following characteristics.

ができる。You can see the light entering from the end of the rope. If the rope is cut, we know that there is a break because there is a change in the light transmission in the optical fiber. Furthermore, if the metal tube is worn out, worn out, or scratched, an abnormality will occur in the transmission of light, which can indicate an accident. '=18 By using a material with a high melting point such as quartz for the optical fiber, it can be used as a four-heat rope. For example 1500°
Stainless steel melts when exposed to heat exceeding 2,000 degrees Celsius, but quartz-based optical fibers at 2,200 degrees Celsius can be used as ropes without breaking due to heat. Therefore, the present invention can be used as an excellent heat-resistant rope for tunnel fires, aircraft, ships, wiring for open equipment, ropes, etc.
