This turbine is provided with: a shaft body (30) supported so that the shaft body (30) can rotate; rotor blade members provided on the outer periphery of the shaft body (30) and forming a row of rotor blades in the circumferential direction of the shaft body (30); a casing surrounding both the shaft body (30) and the row of rotor blades; an outer ring member (72) provided to the inner periphery of the casing and including an inner peripheral section (72a) having an irregularly shaped cross-sectian which continues in the circumferential direction; stator blade members (41) provided in the circumferential direction, the stator blade members (41) respectively having shrouds (43) which are engaged with the inner peripheral section (72a) of the outer ring member (72) and also respectively having stator blade bodies (42) which are extended inward from the shrouds (43) in the radial direction, the stator blade members (41) forming a row of stator blades with circumferentially adjacent shrouds (43) provided close to each other; and a plate-shaped member (71) for connecting at least some of the stator blade members (41) and covering the shrouds (43) of the connected stator blade members (41) from one side in the axial direction to seal shroud gaps formed between the shrouds (43) adjacent to each other in the circumferential direction. |
