PURPOSE:To repair the joining section of an optical fiber at low cost by melting and injecting plastic little by little by utilizing heat and gas pressure generated through the combustion of a combustible substance. CONSTITUTION:When igniting an ignition agent 6, the ignition agent 6 generates a small fire, and ignites a gas generating agent 7 through an internal communicating hole. A high-temperature high-pressure gas generated through the combustion of the gas generating agent 7 is regulated so as not to directly contact with a nylon protective pipe 9 by means of a separator 4, and ejected into space 19 in a case. The gas ejected into the case melts nylon 13 through the nylon protective pipe 9. When the nylon is melted, a pressure valve 12 is opened by gas pressure in the case, pressure is applied to the nylon melted from the small hole of a cap 11, and the nylon melted is injected into a die 15 through a through- hole 14a, is filled into a cavity 17, and coats the joining section 18 of the optical fiber. |
