械。 In an axial flow turbomachine, a plurality of rotor blades fixed to a rotating shaft are arranged opposite to a nozzle integrated in a casing, and a working fluid is supplied to the rotor blades through the nozzles to rotate the rotary shaft. An annular groove coaxial with the rotating shaft is carved on the outer circumferential surface of the shroud attached to the tip of the rotor blade, and one end is fixed to the inner circumferential surface of the casing facing the annular groove of the shroud. An axial flow turbomachine characterized in that an annular fin is protruded from the annular groove, and the other end of the annular fin is inserted into the annular groove with a small gap therebetween.
