Abstract

See full text

A rotor blade is a rotor blade to be attached to a rotor shaft rotatable about an axis, and includes a blade body extending in a radial direction with respect to the axis and having a blade-shaped cross-section orthogonal to the radial direction; a fillet portion provided on a radial outer side of the blade body and having a hollow portion formed therein; a shroud provided on a radial outer side of the fillet portion and extending in a circumferential direction; and a seal fin projecting from the shroud to an outer circumferential side and extending in a direction intersecting the blade body when viewed from the radial direction. A wall thickness on a suction side of the fillet portion is greater than a wall thickness on a pressure side of the fillet portion on a leading edge side of the blade body as demarcated by an intersection portion between the blade body and the seal fin serving as a boundary.
