The axial flow expander(1) includes: an outer casing(2) provided with a suction port(5) and a discharge port(6) through which gas is discharged from the outer casing(2); an inner casing(9) inside which a gas passage is formed and which is provided with a first communication portion(10a) which communicates the gas passage with the suction port(5) and a second communication portion(10b) which communicates the gas passage with the discharge port(6); a rotor shaft(4) which extends in the direction along an axis(P); a bearing(7) configured to bear the rotor shaft(4); stator vanes(31) which protrude inward from an inner periphery of the inner casing(9); and moving blades(32) which protrude outward from the rotor shaft(4). The inner casing(9), the rotor shaft(4), the bearing(7), the stator vanes(31) and the moving blades(32) are integrally assembled, and the assembled members are inserted into the outer casing(2). |
