Abstract

An oil pump driving device includes an oil pump to be driven by either of an engine and an electric motor, and is short in axial dimension. The oil pump driving device includes a first one-way clutch for transmitting motive power from the engine only in one direction, and a second one-way clutch for transmitting motive power from the electric motor only in the above one direction. The first one-way clutch is disposed within an opening formed in a partition wall of a transmission case. The oil pump includes a rotor having an inner peripheral portion defining a hollow space. The second one-way clutch is disposed inside of the inner peripheral portion of the rotor.
