Abstract
A resin tube connection device includes a resin tube, a resin expanding portion and a metal sleeve. The resin expanding portion has a sealing surface being able to come into contact with a contact surface. Further, the resin expanding portion has a second flow path that communicates with a first flow path of the resin tube and opens in the sealing surface. The sealing surface projects farther than an end surface of the metal sleeve in an axial direction. The maximum length of a contact region where the resin expanding portion and the metal sleeve come into contact with each other in the axial direction in an outer surface is larger than the thickness of a resin layer in a radial direction.
