Claims

[Claims for Utility Model Registration] In a tube connection structure in which a tube 2 is attached to a circumferential wall 1 so as to pass through the circumferential wall, the inner circumferential surface of a tube insertion hole 1A formed in the circumferential wall 1 and the tube end portion 2A inserted therein. A deformable bushing 4 is interposed in the annular gap between the tube 2 and the outer peripheral surface, and the tube 2 is disposed on the inner end side of the tube 2.
A retaining part 5 is formed to prevent the bushing 4 from being removed from the bushing, and the outer end surface of the bushing 4 is pressed against the retaining part 5 to pinch the bushing 4 from the tube axis direction. A pressing tool 7 is attached to the pipe 2 to deform it and fix the bush 4 under pressure to the inner circumferential surface of the tube insertion hole 1A and the outer circumferential surface of the tube end 2A.
Pipe connection structure installed in. The pipe connection structure according to claim 1, wherein the peripheral wall 1 is a peripheral wall of a main body pipe for transporting fluid, and the pipe 2 is a branch pipe. The pipe connection structure according to claim 1, wherein the pressing tool 7 is a nut that is screwed onto the pipe 2.
