Abstract
A hybrid drive device having an engine coupling shaft member, a speed change mechanism, a rotating electrical machine, and an engine connecting clutch. A first lubricating oil passage scatters lubricating oil from radially inside to radially outside of first and second friction plates. A first one-way clutch is interposed between an engine coupling shaft member and a coupling member, and is configured to not be engaged when rotation of the engine coupling shaft member becomes lower than rotation of the coupling member. A second one-way clutch is configured not to be engaged when rotation of the rotating electrical machine becomes lower than rotation of the coupling member. An engine driven oil pump generates an oil pressure to be supplied by a driving force of the internal combustion engine or a driving force of the rotating electrical machine regardless of engagement or disengagement of the engine connecting clutch.
