A driving wheel bearing device is disclosed. The driving wheel bearing device comprises: a wheel hub connected to be integrally rotated with a vehicle wheel; two inner wheels coupled to be integrally rotated to the wheel hub; an outer wheel inserting the wheel hub and the inner wheel to support; and a power transmission member coupled to be integrally rotated to the inner wheel among the inner wheels. Power is smoothly transmitted between a wheel bearing and the power transmission member, and manufacturing costs can be reduced. |
