Abstract

A hybrid drive device including an electric motor; an automatic transmission; a lubricating oil passage to which a lubricating oil pressure is supplied; and a switching valve that is switched between a first state where the lubricating oil passage communicates with a first lubricating oil passage that guides lubricating oil to the automatic transmission, and a second state where the lubricating oil passage communicates with a second lubricating oil passage that guides the lubricating oil to the electric motor. The electric motor and an internal combustion engine output shaft are operable in conjunction with the automatic transmission. The switching valve is switched from the first state to the second state when a vehicle is in a stationary state or running at a speed of a predetermined value or less including the stationary state of the vehicle.
