Abstract

See full text

A seal device for a turbine includes: a plurality of thin plates arranged along an outer peripheral surface of the rotor, each of the thin plates including a root portion disposed on an outer side in a radial direction of the rotor and supported on a stationary part of the turbine and a tip portion disposed on an inner side in the radial direction of the rotor and having a tip surface facing the outer peripheral surface of the rotor. Each of the thin plates is configured such that a width direction of the thin plate is parallel to an axial direction of the rotor at a side of the root portion, and the tip portion of each of the thin plates is configured such that an end on a side of the high-pressure space is positioned downstream of another end on a side of the low-pressure side.
