1. A driving device for a vehicle, the driving device comprising:
a carrier supported on a vehicle body;
a ring gear installed such that a rotation axis thereof is concentric with a central axis of the carrier;
a wheel hub coupled to the ring gear with splines;
a sun gear having a rotation axis parallel to the rotation axis of the ring gear and installed to have a variable inter-axis distance from the rotation axis of the ring gear, the sun gear being configured to receive power from outside;
a final gear supported on the carrier to be meshed with the ring gear;
a link mechanism interconnecting the sun gear and the final gear such that a connection angle changes depending on a change in the inter-axis distance between the sun gear and the ring gear; and
a gear train provided in the link mechanism to continuously establish a power transmission state between the sun gear and the ring gear regardless of the change in the inter-axis distance between the sun gear and the ring gear, wherein a carrier boss protrudes at an outer center of the carrier, and wherein the ring gear is rotatably supported on the carrier boss.
