<p>In a turbine rotor blade and a turbo machine, a plurality of rotor blades (28) are arranged at a predetermined interval in a circumferential direction of a rotor (32), each of these rotor blades (28) includes a blade root (41) fixed to the rotor (32), a blade main body (42) having a proximal end connected to the blade root (41), and a tip shroud (43) connected to a tip end of the blade main body (42) so as to constitute a part of an annular shroud (45), a tip end side of a leading edge (52) of the blade main body (42) is made continuous to an outside surface (43A) of the tip shroud (43) via a curved portion (54) curved toward a trailing edge (53), fillets (51a, 51b) are provided between the tip end of the blade main body (42) and an inside surface (43B) of the tip shroud (43), and the curved portion (54) is located closer to the leading edge (52) than the fillets (51a, 51b), whereby the turbine rotor blade and the turbo machine can realize weight reduction and suppress performance degradation.</p> |
