A driving device includes: an internal combustion engine; a first rotating electric machine; a second rotating electric machine; and a transmission. The transmission includes: a first rotating electric machine shaft; a second rotating electric machine shaft which is arranged in parallel to the first rotating electric machine shaft; a first gear provided in the first rotating electric machine shaft; and a second gear provided in the second rotating electric machine shaft. A width in an axial direction of the first rotating electric machine is larger than that of the second rotating electric machine. The number of gears provided in a shaft in which a gear for the first rotating electric machine that meshes with the first gear is arranged is smaller than the number of gears provided in a shaft in which a gear for the second rotating electric machine that meshes with the second gear is arranged.

Driving device

A lubricating structure of a transmission is capable of supplying a lubricating oil with respect to a clutch promptly and stably. The lubricating structure of the transmission includes a first oil passagewhich extends in a second input shaftfrom one end side thereof to a first position, and the lubricating oil is supplied from the one end side, a second oil passagewhich connects to the first oil passageat the first position and extends in the second input shaftto a second position, a first lubrication holewhich distributes the lubricating oil to the second clutchat the first position, and a second lubrication holewhich distributes the lubricating oil to a transmission mechanismat the second position.
