In the present invention, there is disclosed a steam turbine comprising a moving blade (1) provided with an end plate performed on its head. On the side of the end plate directing toward the moving blade (1), there is performed a drain guide groove (4). On the moving blade (1), there are performed moisture trapping grooves (2), whereby said drain guide groove (4) is situated above the moisture trapping grooves (2). The drain guide groove (4) enters a droplet ejection hole (5) performed in the end plate (3). Moisture, entrapped on the moving blade (1) with the moisture trapping grooves (2) and the drain guide groove (4) is lead into the droplet ejection hole (5), wherefrom it is ejected into a collecting chamber (7). This configuration makes it possible to remove moisture entrapped on the moving blade (1) through the droplet ejection hole (5). |
