Claims

[Scope of Claim for Utility Model Registration] (1) Insert the end of the piping side into the stepped enlarged diameter opening of the joint body, which has a stepped enlarged diameter opening in the connection direction that connects to the flow hole inside the shaft core. In the structure in which the annular protruding wall 3 provided at the end of the pipe P side
an elastic seal ring member 4 is engaged with the back surface of the
Further, a ring-shaped or sleeve-shaped pressing member 5 is incorporated from the outside of the elastic seal ring member, and a cylindrical member 6 has an annular flange wall 6' that abuts and engages the entire surface of the projection wall 3 on the tip side. is inserted into the stepped enlarged diameter opening 2' on the joint body 1 side while being press-fitted inside near the connecting end on the piping P side, and the cylindrical wall forming the stepped enlarged diameter opening. The narrow diameter device is characterized in that the end portion 1' is bent inward to press the pressing member 5 forward, and the elastic seal ring member 4 is compressed and closely engaged with the opposing circumferential surface. Connection structure between the metal pipe end and the fitting body. (2) Utility Model Registration Claims 1. In claim 1, the outer circumferential surface of the annular flange wall 6' of the cylindrical member 6 is
A connection structure between a small-diameter metal pipe end and a joint body, characterized in that it is press-fitted onto the inner circumferential surface of a stepped enlarged diameter port 2'. (3) The small diameter metal according to claim 1 of the utility model registration claim, characterized in that the pressing member 5 has an outwardly extending flange wall 5' at the rear end of the pressing member. Connection structure between the pipe end and the fitting body. (4) Utility Model Registration Claim 1, wherein the narrow-diameter metal pipe end and the joint body are characterized in that the inner circumferential surface of the cylindrical member 6 on the pipe P side is formed into a tapered wall 6''.
