The present invention includes an introducing passage that is provided within a turbine stationary blade fixed within a turbine casing and that communicates an interior of the turbine casing with an exterior thereof; a nozzle that is provided in an inner circumference of the turbine stationary blade in a manner that the nozzle communicates with the introducing passage and that includes an outlet facing the opening of the rotor cavity and a swirler at the outlet; and a pressurizing passage that communicates a cooling passage with a rotor cavity. In this arrangement, the outlet of the nozzle and the connecting opening of the pressurizing passage are arranged so that distances of the outlet and of the connecting opening from the central axis line in the radial direction of the rotor are the same distance r.

In a gas turbine, an exhaust casing and an exhaust chamber are connected by an exhaust chamber support that can absorb thermal expansion, and the exhaust chamber and an exhaust duct are connected by an exhaust duct support that can absorb thermal expansion. An insulator is mounted on an outer peripheral surface of the exhaust chamber, and the exhaust chamber support and the exhaust duct support are disposed outside the insulator in the form of a plurality of strips. Because the thermal stress at a connection portion of the exhaust chamber is reduced, the durability is enhanced.

In a gas turbine, an exhaust casing (27) and an exhaust chamber (14) are connected by an exhaust chamber support (32) that can absorb thermal expansion, and the exhaust chamber (14) and an exhaust duct (31) are connected by an exhaust duct support (33) that can absorb thermal expansion. An insulator (63) is mounted on an outer peripheral surface of the exhaust chamber (14), and the exhaust chamber support (32) and the exhaust duct support (33) are disposed outside the insulator (63) in the form of a plurality of strips. Because the thermal stress at a connection portion of the exhaust chamber is reduced, the durability is enhanced.
