Abstract
A rotor blade () provided in an axial flow compressor () including a rotating shaft, a casing (), a diffuser portion () provided on a downstream side of the casing to communicate with a flow path (C) of the casing and form an annular shape and configured to define a diffuser flow path (DC) in which a cross-sectional area of the flow path expands toward the downstream side, a plurality of stator vane rows (), and rotor blade rows () performing compression of a gas. A plurality of rotor blades are spaced apart from each other in a circumferential direction, and constitute a final rotor blade row (A) positioned on a most downstream side among the rotor blade rows, and include a blade portion () having a larger deflection angle on a hub side and a chip side than at a central portion in a blade height direction.
