An expansion joint includes: an outer tube including first and second ends and extending therebetween, the outer tube including first and second flanges, the first being located at the first end, the second being located at the second end and connectable to a downstream pipe; an inner tube including third and fourth ends and extending therebetween, the inner tube being located inside the outer and including third and middle flanges, the third flange being located at the third end and connectable to the upstream pipe, the middle flange being located at a middle portion between the third and fourth ends; and a closure including an outer peripheral portion connected to the first flange, an inner peripheral portion connected to the middle flange, and an elastic portion connecting the outer and inner peripheral portions. The first end is spaced from the third and located between the third and fourth ends.

An expansion pipe joint that absorbs displacement occurring at a connection portion between an upstream pipe and a downstream pipe includes an outer tube having a downstream end coupled to the downstream pipe, an inner tube that is inserted into the outer tube and has an upstream end coupled to the upstream pipe, and a closing member having elasticity that is provided between an upstream end of the outer tube and the upstream end of the inner tube so as to close a gap between them. Then, a difference between a position in an axial direction of the upstream end of the outer tube and a position in the axial direction of the upstream end of the inner tube is within a predetermined range so that a bus line of the closing member is inclined from the axial direction.
