摘要： PROBLEM TO BE SOLVED: To provide a method and structure for reinforcing a connecting end of a thin small diameter metal pipe, in which the press fitting margin of a press fitting wall portion constituted by a reinforcing pipe is easily machined, the reinforcing pipe is securely fixed to facilitate press-fitting work and positioning of the reinforcing pipe to the connecting end of the metal pipe to be at a fixed position. SOLUTION: In the method for reinforcing the connecting end of the thin small diameter metal pipe, one end of the short reinforcing pipe is slightly enlarged in diameter and/or deformed to form the press fitting wall portion. The other end of the reinforcing pipe is inserted into the metal pipe, and the press fitting wall portion is press-fitted on the inner peripheral face of the metal pipe to fix the reinforcing pipe, so that a connecting portion is formed to be a desired shape near the connecting end of the metal pipe. In a structure for reinforcing the connecting end of the thin small diameter metal pipe, the connecting end structure has a double wall in which the connecting portion of the desired-shape is formed near the connecting end of the metal pipe. One end of press-in portions of the short reinforcing pipe is slightly enlarged in diameter and/or deformed to form the press fitting wall portion. In a portion near the connecting end of the metal pipe, the press fitting wall portion is press- fitted on the inner peripheral face of the metal pipe to fix the short reinforcing pipe.

摘要： PROBLEM TO BE SOLVED: To simplify the structure and provide a large pulling proof stress by mounting the cylinder part of a connector body on a passing hole, closely fitting a seal ring to the inside surface of the passing hole, and engaging and connecting the locking claw of a retainer to the cutout window part of a counter member. SOLUTION: In connection of thin piping, the cylinder part 1A-1 of a connector body 1A is inserted to a passing hole 4 on an oil tank 6 side, and a seal ring 5 is closely fitted to the inside surface of the passing hole 4. The claw piece 2c of a retainer 2 fitted and fixed between the spools 1A-3 of the connector body 1A is engagingly connected to the cutout window part 3-1 of a counter member. To release the connection, the elastic wall of the retainer 2 exposed to the part of the cutout window part 3-1 provided on a cylindrical wall 3 is pressed inward to push the clocking claw 2c into the cylindrical wall 3. According to this, the assembling can be easily and quickly performed, a large pulling proof stress can be provided, and the separation accident of the piping can be eliminated.
