Hybrid vehicle driving apparatus

A hybrid vehicle driving apparatus, comprising:

• an engine;
• a first rotator;
• a second rotator;
• a first differential mechanism configured to transmit a rotation of the engine to a driving wheel side;
• a switching device configured to shift the first differential mechanism, and
• a second differential mechanism that couples the first differential mechanism and driving wheels the second differential mechanism including
• a first rotational element coupled to an output element of the first differential mechanism,
• a second rotational element coupled to the first rotator, and
• a third rotational element coupled to the second rotator and the driving wheels, wherein
• the first rotator is coaxially disposed with the engine, and the second rotator is disposed on a different axis from an axis of the engine to constitute a multiple-axis system,
• the first differential mechanism is coaxially disposed with and between the engine and the first rotator,
• the switching device is disposed at an opposite side from the engine with respect to the first rotator,
• the second differential mechanism is coaxially disposed with and between the first differential mechanism and the first rotator,
• a counter drive gear is coupled to the third rotational element, and
• the counter drive gear is disposed at an outer circumference side of the first differential mechanism,
• the first differential mechanism is a first planetary gear mechanism including a first sun gear, a first pinion gear, a first ring gear, and a first carrier,
• the switching device includes a clutch configured to couple the first sun gear and the first carrier,
• a coupling shaft that couples the first sun gear and the clutch passes through an inside of a rotation shaft of the first rotator, and
• the first carrier is coupled to the clutch via an input shaft which is coupled to an output shaft of the engine.
