PROBLEM TO BE SOLVED: To provide a moving blade capable of reducing rotational friction loss, having a robustness to fluctuation of a spread angle of flow, and capable of improving performance and reducing a development cost, and provide an axial flow turbine.SOLUTION: A plurality of moving blades are disposed on a turbine rotational shaft of an axial flow turbine, along the circumferential direction of the turbine rotational shaft. The moving blade includes: a blade part extending from a root part to a tip; and a substantially triangle-shaped cover that is disposed at the tip of the blade part, and of which a cross sectional shape in an axial direction along the turbine rotational shaft has a boundary part with the blade part as one vertex.SELECTED DRAWING: Figure 2 |
