摘要：
A turbine is provided including an annular turbine blade body (50) disposed on a flow path, a diaphragm outer ring (11) installed at a tip side of the blade body via a clearance, and seal fins (12A, 12B, 12C) formed to protrude from the diaphragm outer ring (11) and configured to form small clearances (13A, 13B, 13C) with the annular turbine blade body (50), wherein dead water region-filling sections (15, 17, 19) are formed in cavities (C1, C2, C3) in which main vortexes (SU1, SU2, SU3) are generated, such that a dead water region that the main vortexes (SU1, SU2, SU3) cannot reach is filled.
