Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a rotary machine capable of more effectively reducing a leakage flow.SOLUTION: A gas turbine is provided with an annular groove 17 for accepting a hub shroud 81 and secures a gap between the hub shroud 81 formed at a position corresponding to the hub shroud 81 of an rotor 7. Seal fins 15a, 15b are installed in an erected manner on the hub shroud 81 towards a bottom surface 17a of the annular groove 17 and minute gaps H (H1, H2) are formed in a radial direction between the tip ends of the seal fins 15a, 15b and the bottom surface 17a of the annular groove 17. A recess 18 for changing several times the flowing direction of leaked fluid J that flows towards a low-pressure side from the minute gaps H is installed on an inner surface 17b on the low-pressure side of the annular groove 17.
