Abstract:
1. A drive apparatus for a hybrid vehicle, comprising: an input shaft configured to be rotatably connected to an engine; a motor including a rotor and a stator, the stator being positioned outwardly relative to the rotor in a radial direction of the motor and being held inside a stator holder which has a flange portion extending in a direction perpendicular to a rotation axis of the rotor; an output shaft arranged coaxially with the rotation axis of the rotor and connected integrally with the rotor; a clutch device selectively engaging the input shaft with the output shaft; and a case supporting the input shaft and the output shaft in a manner that the input shaft and the output shaft are rotatable about the rotation axis, accommodating the motor and the clutch device, and including an oil sump for pooling oil; wherein the case includes an end face portion to which the flange portion of the stator holder is fixedly attached; at least one recessed portion is provided on a peripheral wall portion of the case, at a position where the peripheral wall portion is located lower than a level of the oil pooled in the oil sump and where the peripheral wall portion faces the stator holder; and the recessed portion extends in a direction of the rotation axis beyond an axial end face of the stator holder in the direction of the rotation axis and extends to reach the end face portion to provide a fluid communication within the oil sump which is separated by the stator into a front oil sump and a rear oil sump in the direction of the rotation axis.
