PROBLEM TO BE SOLVED: To reduce a quantity of flexible joints while avoiding stress generated by thermal expansion of a turbine from being exerted upon a clutch device, to reduce a size and a construction cost, and to improve the accuracy of alignment.SOLUTION: In a combined generator 30, a turbine of which at least thermal expansion amount is larger (for example, a steam turbine 3) out of a power turbine 2 and the steam turbine 3, has: one end in its axial direction L that is fixed to an upper face of a foundation part to form a thermal expansion starting point 11; and the another end in the axial direction L that is movably arranged so as to be movable in only the axial direction L with respect to an upper face of the foundation part to form a thermal expansion moving point 15. A relative movement structure A is provided which prevents stress generated by the movement of the thermal expansion moving point 15 from being exerted on a clutch device 7. In the relative movement structure A, for example, the thermal expansion starting point 11 is provided on the clutch device 7 side of the turbine 3, and the thermal expansion moving point 15 is provided on the side opposite to the clutch device 7 of the turbine 3. |
