Claim Text:
1. A hybrid drive device, comprising: an engine coupling shaft member that is drivingly coupled to an internal combustion engine; a speed change mechanism that shifts rotation received by an input shaft member and outputs the shifted rotation to a wheel; a rotating electrical machine drivingly coupled to the input shaft member; a housing case containing the rotating electrical machine; an engine connecting clutch that has a first friction plate drivingly coupled to the engine coupling shaft member, a second friction plate drivingly coupled to the input shaft member, and a hydraulic servo engaging or disengaging the first friction plate and the second friction plate, and that has both the first friction plate and the second friction plate placed in the housing case; a first lubricating oil passage that scatters lubricating oil from radially inside to radially outside of the first friction plate and the second friction plate to lubricate the first friction plate and the second friction plate; a coupling member; a first one-way clutch that is interposed between the engine coupling shaft member and the coupling member, and that is not engaged when rotation of the engine coupling shaft member becomes lower than rotation of the coupling member; a second one-way clutch that is interposed between the rotating electrical machine and the coupling member, and that is not engaged when rotation of the rotating electrical machine becomes lower than rotation of the coupling member; and an engine driven oil pump that is drivingly coupled to the coupling member and generates an oil pressure to be supplied to the first lubricating oil passage 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.
