1. A drive device for a hybrid vehicle, the hybrid vehicle including an engine, at least one drive wheel, and a motor arranged on a different rotational axis from a rotational axis of the engine, the drive device comprising:
a driven gear shaft arranged to be rotatable about a rotational axis that is shared with a rotor shaft of the motor, the driven gear shaft being connected to the rotor shaft of the motor to allow power transmission between the driven gear shaft and the rotor shaft; a driven gear configured to receive power from the engine, the driven gear being provided on the driven gear shaft; an output shaft arranged to be rotatable about the rotational axis that is shared with the rotor shaft of the motor, at least a portion of the output shaft being arranged at a position where the portion overlaps the driven gear shaft in a radial direction of the output shaft, the output shaft being connected to the rotor shaft to allow power transmission between the output shaft and the rotor shaft, and the output shaft being connected to the drive wheel to allow power transmission between the output shaft and the drive wheel; a first bearing device that rotatably supports the rotor shaft of the motor on a driven gear side in an axial direction of the rotor shaft; a second bearing device that rotatably supports one of the driven gear shaft and the output shaft, the one of the driven gear shaft and the output shaft being arranged radially inward of the other one of the driven gear shaft and the output shaft; and a third bearing device arranged between an outer periphery of the one of the driven gear shaft and the output shaft and an inner periphery of the rotor shaft or an inner periphery of the other one of the driven gear shaft and the output shaft, the third bearing device that rotatably supports the one of the driven gear shaft and the output shaft. |
