ABSTRACT:
A transmission unit comprises a differential gear unit having a pair of side-journals rotatably supported by a pair of axially spaced side-bearings carried on a pair of carrier portions of a casing for the transmission unit, a pair of wheel axles extending outwardly through the respective side-journals from the differential gear unit in an opposite direction and surrounded by a pair of annular seal members carried on the respective carrier portions, a pair of annular shim plates interposed between each of the carrier portions and each of the side-bearings, and a pair of oil passages for leading lubricating oil into a pair of annular side-spaces formed around each of the wheel axles between the respective side-bearings and the respective seal members. Each of the annular shim plates is formed at the inner peripheral portion thereof with a number of circumferentially spaced radial projections and recesses which are arranged to radially lead the lubricating oil onto each of the wheel axles for lubrication of the side-journals.
