<p>PROBLEM TO BE SOLVED: To provide a coupling structure of a flexible tube and a tube joint capable of repairing at a low cost by repairing or replacing only a damaged part even when a damage occurs by restricting a part to be brought into contact with fluid to a flexible tube while removing a clearance between a metal fitting and the flexible tube with the fluid to remove a cause of corrosion. SOLUTION: This coupling structure of the flexible tube and the tube joint is constituted by a tube joint metal fitting fixed on a tip part of a flexible tube covered with a blade on an outer periphery thereof, an inside large diameter step part formed on an end of the tube joint metal fitting, a sealing material fitted in the inside large diameter step part while extending a forward extending part of the flexible tube to the inside large diameter step, and a caulking ring caulking an end of the blade covered on the outer periphery of the flexible tube with a backward protruding part of the tube joint metal fitting along the shape thereof.</p> |
