Driving device for hybrid vehicle

A driving device for a hybrid vehicle, the driving device comprising:

• a power transmission mechanism connected to an engine, the power transmission mechanism configured to transmit a rotation of the engine;
• a differential mechanism that connects the power transmission mechanism to driving wheels;
• and
• a switching device configured to perform speed change of the power transmission mechanism,
• wherein the differential mechanism includes a first rotary element that is connected to an output element of the power transmission mechanism, a second rotary element that is connected to a first rotating electrical machine and a third rotary element that is connected to a second rotating electrical machine and the driving wheels,
• the rotation of the output element of the power transmission mechanism is limited by the switching device, and
• the driving device has a mode of limiting a rotation of the output element of the power transmission mechanism by the switching device and traveling with the first rotating electrical machine and the second rotating electrical machine used as power sources.
