<p>Provided is an expansion/contraction flexible joint capable of handling a large amount of expansion despite having a limited length. This expansion/contraction flexible joint (3) is characterized by being equipped with: a first sleeve (6) into which the end of a first pipe (1) is inserted; an outside sleeve (7), which is provided on the outside of the first sleeve and overlapping the first sleeve, and is capable of relative movement with respect to the first sleeve in the axial direction, and into which the end of a second pipe (2) is inserted; a first sealing material (17); a second sealing material (18); a third sealing material (19); a first restricted-length part (24) having a first stopper (27) that restricts the axial movement of the first pipe and the first sleeve; and a second restricted-length part (25) having a second stopper (28) that restricts the axial movement of the second pipe and the outside sleeve.</p> |
