A combined power generation unit requires fewer flexible couplings to prevent stress due to thermal expansion of a turbine from being transferred to a clutch device, thus achieving a smaller size, a lower construction cost, and a higher alignment accuracy. In a combined power generation unit (30), at least one of a power turbine (2) and a steam turbine (3), whichever experiences a larger amount of thermal expansion (e.g., the steam turbine (3)), includes a thermal expansion starting point (11) located at one end in an axial direction L and fixed to a top surface of a foundation and a thermal expansion moving point (15) located at another end in the axial direction L and arranged to be movable relative to the top surface of the foundation only in the axial direction L. A relative movement structure (A) is provided that prevents stress due to movement of the thermal expansion moving point (15) from being transferred to a clutch device (7). For example, the relative movement structure (A) is configured such that, whereas the thermal expansion starting point (11) is directed toward the side of the turbine (3) facing the clutch device (7), the thermal expansion moving point (15) is directed toward the side of the turbine (3) facing away from the clutch device (7).
