This turbine is provided with a sealing device (40). The sealing device comprises: at least one step face (42) which is provided in a region of an outer circumferential surface of a rotor (5) facing a shroud (35) of a stator vane (20)in the radial direction of the rotor, and which faces upstream in the direction of flow of a fluid, and which divides the region of the outer circumferential surface into at least two segments (50A, 50B) in the axial direction of the rotor; at least two sealing fins (44A, 44B) which respectively project from the stator vane toward the at least two segments, and respectively face the at least two segments across a sealing gap (52A, 52B); and a swirl component imparting portion (46) which is provided at one end side, in the axial direction of the rotor, of the shroud of the stator vane, and is capable of imparting a swirl component to the fluid flowing toward the sealing gap.
