Zusammenfassung:	PROBLEM TO BE SOLVED: To disclose a steam turbine rotating blade (20) for a low-pressure section of a steam turbine engine (10). SOLUTION: The steam turbine rotating blade (20) includes a blade-shaped section (42). A root section (44) is fitted to one end of the blade-shaped section (42). A dovetail section (40) includes a tangential direction inserting type dovetail that is a dovetail section (40) protruding from the root section (44). An apical end section (46) is fitted to the blade-shaped section (42) at an end opposite to the root section (44). A cover (48) is formed integrally with the apical end section (46) as a part of the apical end section (46). The rotating blade (20) includes an annular outlet space area lager than about 18.1 ft2(1.68 m2). COPYRIGHT: (C)2010,JPO&INPIT
