Patent attributes
In a drive apparatus, a ring gear of a differential device is rotatable about a third axis in a direction opposite to a counter gear of a deceleration device. The inner surface of the gear housing accommodating the deceleration device, the differential device, and the reservoir capable of storing a fluid includes first and second curved surfaces disposed in the +X direction with respect to the third and second axes, respectively. At least a part of the first curved surface faces the radially outer end portion of the ring gear in the radial direction and extends in the circumferential direction. At least a part of the second curved surface faces the radially outer end portion of the counter gear in the radial direction and extends in the circumferential direction. The position of the reservoir in the Y-axis direction overlaps the first curved surface and the second curved surface.
