Abstract
(EN)
The present invention relates to a driving device for an electric automobile. The driving device for an electric automobile, according to one embodiment of the present invention, comprises: a speed reduction gear set which comprises a first speed reduction gear set and a second speed reduction gear set which are coupled to a differential shaft extending from a differential gear; an oil storage space which is formed on the lower part of at least one among the first speed reduction gear set and the second speed reduction gear set; and an oil flow path in which oil flows from the oil storage space to the upper part of a case cover when the speed reduction gear set rotates inside the case cover.
