ABSTRACT:
Connection structure for connecting a piping used in automobiles or the like to a ring joint for providing highly reliable gas-tightness. The ring joint includes a ring joint body including a fitting hole for an eyebolt, the fitting hole being piercingly formed in an axial core portion of the ring joint body and in continuation from an annular recessed groove formed inside the ring joint body, and a flow path extending in a direction perpendicular to and intersecting with the fitting hole. A branch pipe is formed as a unitary body with the ring joint body and arranged in a direction perpendicular to and intersecting with the eyebolt. A piping for insertion into the branch pipe has an outer peripheral surface covered with resin, and the resin of the outer peripheral surface of the piping and an inner peripheral surface of the branch pipe are fixedly welded to one another.
