<p>A gas turbine includes an exhaust chamber (34) defined by a cylindrical casing wall (51) and a bearing case (52) that supports a bearing part (42) of a rotor (4) in the casing wall, struts (53) that are provided at equal intervals in the circumferential direction of the bearing case and extend in the tangential direction of the bearing case to couple the casing wall and the bearing case, a diffuser unit (54) having an outer diffuser (54a) at the inner periphery of the casing wall and an inner diffuser (54b) at the outer periphery of the bearing case, a cooling chamber (55) in which the outer diffuser and the inner diffuser are coupled by a strut cover (53a) for covering each of the struts and that is led to a portion between the casing wall and the outer diffuser, a portion between the bearing case and the inner diffuser, and the insides of the strut cover, and a partition wall (56) that covers the outer periphery of the bearing case between the bearing case and the inner diffuser.</p> |
