PROBLEM TO BE SOLVED: To provide a vibration isolation pipeline joint which is space-saving, and can absorb greater displacement. ;SOLUTION: This vibration isolation pipeline joint 50 for connecting two pipelines with each other, which are provided for a foundation 20 and a vibration isolation structure 30 while being vertically faced to each other, by letting the constitution be so constructed as to be provided with a connecting pipe line 53 composed of a flexible pipe 51 interposed between the two pipelines while an excess length is being provided, and of a S-shaped pipe 52 to be connected with the flexible pipe 51, and with joints 54 provided for both the ends of the S-shaped pipe 52, the displacement due to earthquakes and the like of the pipelines for the foundation 20 and the vibration isolation structure, can be absorbed by making the S-shaped pipe 52 revolving, and the flexible pipe 51 having excess in length.;COPYRIGHT: (C)1999,JPO
