PROBLEM TO BE SOLVED: To provide a power device provided with a water-cooled type internal combustion engine and a stirling internal combustion engine, in which engine speed of the stirling engine is controlled when heat energy of exhaust gas is extremely small, so that heat energy recovering quantity from exhaust gas is improved to further promote warm-up performance of the internal combustion engine. SOLUTION: This power device is provided with the water-cooled type internal combustion engine, the stirling engine, and a control device. The stirling engine is provided with a heater to heat actuation gas by exhaust gas of the internal combustion engine, and a cooler to cool actuation gas by cooling water for the internal combustion engine. The control device increases engine speed of the stirling engine by reducing a load Ls when the internal combustion engine is in a warm-up state, with the load Ls on the stirling engine exceeding the minimum load (S4-S7). It increases the engine speed Ns by rotation-driving the sterling engine by a motor when the internal combustion engine is in the warm-up state, with the load Ls at the minimum load (S9-S13).
