Abstract
A drive unit for vehicles that prevents a blow out of lubrication oil from a breather during splash lubrication is provided. A partition plate is disposed along a flat face of a ring gear to divide an inner space of the chamber into a first reservoir in which the ring gear is disposed, and a second reservoir to which the lubrication oil partially flows thereinto to return to an oil pan. The partition plate comprises a main body disposed between the flat face of the ring gear and an inner face of the chamber opposed thereto, and a bent portion formed on an upper end of the main body to guide the lubrication oil scattered upwardly by a rotation of the ring gear in a direction away from the breather.
