Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for forming a lubricant film in which a lubricant film is formed at each gear constituting a power transmission device for a vehicle, thus fuel consumption can be improved by beforehand engaging the gear and performing a running-in operation, the power transmission device for a vehicle, and a running-in operational method for the power transmission for a vehicle.SOLUTION: Before the factory shipping of a vehicle provided with a power transmission device for a vehicle such as a differential gear and a manual transmission, the running-in operation of the power transmission device for a vehicle is performed in a state where each gear 1 is engaged for a prescribed time using lubricating oil 12 comprising an organic molybdenum compound and whose temperature is regulated inside a prescribed temperature range, thus a lubricant film 3 comprising molybdenum disulfide is formed at a gear surface 2 of the gear 1.
