Abstract
A power train device for a vehicle is provided with a selector valve that is switched between a first state in which oil discharged from an electric oil pump is able to be supplied as a hydraulic fluid to an engagement hydraulic chamber of a vehicle-starting frictional engagement element, and a second state in which the oil is able to be supplied as a lubricating oil to the vehicle-starting frictional engagement element through a first lubricating oil supply circuit, depending on a magnitude of a discharge pressure of a mechanical oil pump.
