Abstract
A final reduction gear unit comprises a small diameter pinion gear 10, a large diameter ring gear 20 which meshes with the small diameter ring gear 10, a housing for accommodating the two gears, first bearings 26a, 26b for rotatably supporting the large diameter ring gear and second bearings 15a, 15b for rotatably supporting the small diameter pinion gear. Moreover, a gutter member 30 is provided within the housing for receiving the part of lubricating oil thrown up and splash supplied toward the second bearings by the rotation of the large diameter ring gear, and a lubricating oil supply path 6a, 6b, 7a, 7b is formed within the housing which links up with the first bearings at one end and with the gutter member at the other end thereof.
