Abstract
A turbo-generator has a tapering cooling part positioned between a vapor turbine part and a generator part, and casings of these parts are combined together to form a sealed single-boundary structure. A turbine shaft in the vapor turbine part, a rotary shaft in the cooling part and a generator shaft in the generator part are combined unitarily and are supported by bearing parts in such a way that the unitary shaft does not pass from the boundary structure. The tapering cooling part has a smaller diameter at the side of the generator part, and the inner circumferential surface of the cooling part forms a labyrinth structure to separate the atmospheres of the vapor turbine part and the generator part.
