Beschreibung
Zusammenfassung:	A hybrid drive employing an engine (150) and two electric motors (MG1,MG2), has an oil pressure generator or pump (20) which includes a drive gear (30), a driven gear (32), and a crescent (34), which constitute a gear pump unit, as well as one-way clutches (36) and (38) that respectively interlock with two rotating shafts (42,156) and (46,126) when the rotating shafts (42,156) and (46,126) rotate in an identical direction relative to the drive gear (30). In case that both the rotating shafts (42,156) and (46,126) rotate in the interlocking direction, the corresponding one-way clutch interlocks with the rotating shaft having a greater revolving speed, thereby driving the drive gear (30). This structure enables the oil pressure generator (20) to produce an oil pressure through rotation of the rotating shaft having a greater revolving speed out of the two rotating shafts (42,156) and (46,126).
