Abstract
A final drive gearing of a power transmission unit comprises a drive pinion shaft supported by a pair of axially spaced bearings carried on an upright partition wall of a trans-axle casing and a drive pinion integral with the drive pinion shaft and in mesh with a crown wheel for driving a differential gear unit. In the trans-axle casing, an axial cavity is provided on the partition wall adjacent the drive pinion shaft and opens toward the crown wheel to receive therein lubrication oil dipped up by rotation of the crown wheel, a lateral hole is provided through the partition wall to communicate the cavity into an annular space around the drive pinion shaft between the bearings, and a projecting rim is further provided on the partition wall for surrounding upper and side opening edges of the cavity to collect the lubrication oil into the cavity.
