PROBLEM TO BE SOLVED: To relatively simply install, on the outer diameter of a flexible joint 4, a cut-off cover 20 that allows movements in a central axial direction and a radial direction of a pipeline 3 for fluid circulation, and whose overhanging to the outer diameter side of a connection portion of the pipeline 3 and the flexible joint 4 is made small, without loosening a fitting member of the flexible pipe 4 installed in the middle of the central axial direction of the pipeline 3.SOLUTION: A pair of support parts 40, 50 of a cut-off cover 20 includes: a pair of inside members 41, 51 arranged so as to be overlapped inside the axial directions of one end side annular part 4a and the other end side annular part 4b of a flexible joint 4 from the respective central axial direction; a pair of outside members 42, 52 arranged outside the central axial directions of one end side separation portion 3a and the other end side separation portion 3b of a pipeline 3; and a fastening member 82 fastening the pair of inside members 41, 51 and the pair of outside members 42, 52.SELECTED DRAWING: Figure 2 |
