Abstract
An electric driving apparatus according to an embodiment of the present invention includes: a housing; an electric machine comprising a motor shaft rotatably supported by the housing; a first speed reduction portion comprising a first speed shifting shaft capable of being rotationally driven by the motor shaft and configured to shift and transmit a rotational driving force of the motor shaft at a predetermined first speed shifting ratio; a second speed reduction portion comprising a second speed shifting shaft capable of being rotationally driven by the motor shaft and configured to shift and transmit the rotational driving force of the motor shaft at a predetermined second speed shifting ratio; and a double clutch unit configured to receive the rotational driving force of the first speed shifting shaft or the second speed shifting shaft and is configured to selectively rotationally drive at least one of a first output shaft and a second output shaft by the transmitted rotational driving force.
