SEAL MEMBER, TURBINE, AND GAS TURBINE

摘要

A stator blade has: a stator blade body extending radially with respect to the axis; an outer shroud provided at the radially outer end of the stator blade body; an inner shroud (8b) provided at the radially inner end of the stator blade body and forming a main flow passage for combustion gas between the inner shroud (8b) and the outer shroud; and a retainer (8d) protruding inward radially from the radially inner surface of the inner shroud (8b). The retainers (8d) of circumferentially adjacent stator blades are circumferentially adjacent to each other with a third gap therebetween. The third gap is closed by a seal member (20b) which is positioned in such a manner that, relative to one end thereof, the other end is located in the combustion gas downstream in the direction of the axis.
