A thermoelectric unit (110) is provided for an engine (10), through which cooling water flows. A part of cooling water circulates through the engine (10) and a radiator (21), where cooling water is cooled. Cooling water of a discharge side of the engine (10) and that of a discharge side of the radiator (21) are respectively used as a high-temperature side heat source and a low-temperature side heat source of the thermoelectric unit (110). Thus, the thermoelectric unit (110) is provided with a steady temperature difference to generate power, without increasing a component number and deteriorating a cooling of the engine (10). |
