摘要： A connection-structure of a flexible tube, in which the flexible tube is fitted to an end portion of a metal pipe, comprises an annular projection, a first radially enlarged portion, a seal ring and a second radially enlarged portion. The annular projection is formed on an outer surface of the end portion of the metal pipe. The first radially enlarged portion is formed on the tip side of the metal pipe relative to the projection, defining a first annular groove with the projection. The seal ring is fitted into the annular groove. The second enlarged portion is formed on the base side of the metal pipe relative to the projection, defining a second annular groove with the projection. The tip portion of the flexible tube is positioned close to the maximum diameter portion of the second enlarged portion.
