    摘要： Provided are turbine blades and a gas turbine capable of damping the vibrations caused by an excitation force and facilitating mounting/disassembly. Included are a shroud portion (13) disposed at an end portion of an airfoil portion (12); a holder casing (14) that can slide relative to the shroud portion (13), that can also be attached thereto/detached therefrom, and that forms a space with the shroud portion (13) therebetween; and an elastic portion (15) that is disposed in the space, that biases the shroud portion (13) in a direction that separates it from the holder casing (14), and is disposed in a movable manner relative to the shroud portion (13); and a pressing portion (16) that is disposed between the elastic portion (15) and the holder casing (14) and that can be moved toward and away from the shroud portion (13).

    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.
