<P>PROBLEM TO BE SOLVED: To provide a pipe joint capable of immediately and surely preventing a pipe from being drawn out when draw-out force works to the pipe. <P>SOLUTION: An outer tube 2 has a tapered inner peripheral surface 14 shrinking toward a tip opening. A stopper ring 20 fitted over the tip of the pipe P inserted into a storage space 5 is provided. Although the stopper ring 20 comes into slide contact with the tapered inner peripheral surface 14 to shrink and deform, a preload spring 22 is added to elastically urge the stopper ring 20 constantly toward the tapered surface 14. <P>COPYRIGHT: (C)2010,JPO&INPIT |
