In the case where a power unit (U) integrally provided with an engine (13) and an HST (24) provides joint use of oil both as lubricating oil for the engine and as working fluid for the HST (24), the joint use oil is fed from the engine (13) to the HST (24) after it is cooled, thereby preventing the viscosity of the joint use oil from lowering, thus achieving prevention of efficiency lowering and seizure on the HST (24) side.
