Claims

[Claims for Utility Model Registration] 1. Inside the enlarged diameter opening of the mating member 1, which is provided with a cylindrical wall 1' having a stepped enlarged diameter opening 2' in the connecting direction and connected to the communication hole 2 inside the shaft center, at least one elastic seal ring member 5 on the outer periphery of the back surface of the protruding wall on the side of the pipe P having an annular protruding wall 3 extending outward at the connecting end;
A sleeve 6 having an outwardly pressing flange wall 6' is assembled and inserted into the pressing member 7 and the tip thereof, and the pressing member 7 is pressed forward and forms the enlarged diameter opening 2'. The end periphery 1'' of the cylindrical wall 1' is bent inward and the elastic seal ring member 5 is compressed to tightly engage the opening periphery on the enlarged diameter port 2' side and the outer periphery on the piping P side. A structure for connecting and fixing ends of small diameter metal pipes, characterized in that the end portions of small diameter metal pipes are connected together. A structure for connecting and fixing an end portion of a small diameter metal pipe, characterized in that: 3. In the utility model registration claim 1, an enlarged diameter portion 9 is formed at the tip portion on the side of the pipe P;
The sleeve 6 incorporated in the outer peripheral part of the pipe P
A structure for connecting and fixing an end of a small diameter metal pipe, characterized in that a reduced diameter part 11 is formed on the rear end side to come into pressure contact with the outer peripheral part of the pipe P. 4. In the utility model registration claim 1, an outward flange wall 7 is provided at the rear end peripheral edge of the pressing member 7.
What is claimed is: 1. A structure for connecting and fixing an end of a small diameter metal tube, characterized in that the structure has the following features:
