<P>PROBLEM TO BE SOLVED: To provide a pipe joint allowing a smooth flow when fluid flows out and preventing disengagement due to breakage of a buffer projection even when a pipe is excessively slid. <P>SOLUTION: An expansive and vibration-resistant pipe joint 100 includes a trunk 110 with one end of each of many pipes 101 inserted thereinto and a storage step so formed in an inner periphery of an end with the pipe inserted thereinto as to expand an inside diameter, a packing placed on the storage step, a pressure member placed so that the packing contacts the one end, a cap 140 coupled to the trunk with the pipe inserted thereinto so that the packing and the pressure member are incorporated, and a buffer means for absorbing expansion and contraction of the pipe. Since pipe expansion, contraction or deformation is absorbed to keep constant an inside diameter of the entire pipe, a flow pressure of the fluid flowing inside the pipe is kept constant to result in a smooth fluid flow. <P>COPYRIGHT: (C)2012,JPO&INPIT |
