部。 At the joint of a metal tube containing an optical fiber, in which metal tubes containing an optical fiber are connected to each other, the optical fibers protruding from the ends of both metal tube bodies become optical fibers. Both of the metal pipe bodies are connected at a connecting part, and a threaded part is provided on the outer periphery of each end of the two metal pipe bodies, and a recessed joint type connecting pipe is screwed into the threaded part of one of the metal pipe bodies, and the other metal pipe body has a threaded part. A convex joint type connecting pipe is screwed into the threaded portion of the metal tube body, and both of the connecting pipes accommodate the optical fiber and the optical fiber connecting portion existing between the ends of the metal tube bodies. In this state, the concave joint and convex joint are connected by threaded fitting, and a sealing material is interposed between the fitting surfaces or abutting surfaces of the concave joint and the convex joint, and each of the metal pipe bodies A metal containing optical fiber, characterized in that a seal seat is screwed onto the outer periphery of the tip end of the threaded portion, and together with a sealing material, a seal is formed between each of the connecting pipes and each of the metal tube bodies inside the connecting pipes. pipe connection.
