An elbow-equipped expansion joint, even when there is an axial and lateral displacement between a first pipe and a second pipe, can absorb the displacement and connect the first pipe and the second pipe. The elbow-equipped expansion joint includes: an expandable joint including a first sleeve and a second sleeve; and a pair of rotatable elbows joined to both ends of the expandable joint. The elbows each include one elbow pipe, and the other elbow pipe rotatably joined to the one elbow pipe. The bend angle of each elbow can be changed by rotating the other elbow pipe.
