摘要： A steam turbine includes two or more rotating blades and a diaphragm outer ring. Each of the rotating blades includes a tip cover, moisture-trapping grooves, a droplet ejection hole, and a drain guide groove. The tip cover is provided to a tip of each of the rotating blades and is connected in contact with another tip cover adjacent to the tip cover. The moisture-trapping grooves are formed in a longitudinal direction of each of the rotating blades. The droplet ejection hole is to connect an outside of the tip cover on a side of the diaphragm outer ring with an inside of the tip cover. The drain guide groove is to connect ends of the moisture-trapping grooves on the side of the tip cover with the droplet ejection hole. The diaphragm outer ring includes a drain pocket which faces the droplet ejection hole.
