の障害となっていた。<Problems to be Solved by the Invention> However, when using a wire coating device with this structure to coat the surface of an optical fiber with resin liquid, the following problems occur when the optical fiber is broken or the brief form is replaced. Before passing the fiber through, it was necessary to clean the inside of the device to be subjected to riI in advance. The reason for this is that most of the resin solutions currently used for coating optical fibers have a viscosity of less than 30,000 cp before curing, and even after the supply of the resin solution is stopped, the resin i8 ? The fl flowed out and adhered to the fiber passage portion, creating an obstacle when drawing and pulling out the fiber.
