Drive unit of hybrid vehicle

A drive unit of a hybrid vehicle, comprising:

• an engine;
• an electric motor;
• a first differential mechanism;
• a second differential mechanism;
• a selectable one-way clutch;
• and
• a case accommodating the electric motor, wherein
• the first differential mechanism includes a first rotational element coupled to the electric motor, a second rotational element coupled to the engine, and a third rotational element that outputs power toward drive wheels,
• the second differential mechanism includes a sun gear coupled to the electric motor, a carrier coupled to the engine, a ring gear whose rotation is regulated by the selectable one-way clutch, and a ring gear flange that rotates integrally with the ring gear, and
• the selectable one-way clutch is configured to switch a state thereof between a locked state in which a rotation direction of the ring gear is regulated in one direction and an unlocked state in which the ring gear is allowed to rotate in both directions, and
• the ring gear flange is supported by a rotor shaft of the electric motor via a radial bearing.
