摘要： A vehicle final reduction gear unit includes a first friction brake positioned between a right case member which is a stationary body and a differential case which is a rotating body for applying a pressing force in an axial direction to generate a frictional force in order to put a brake on the differential case. A second friction brake occupies an area between the differential case and the right wheel and applies a pressing force in the axial direction to generate a frictional force in order to use a rotational difference to put the differential mechanism into a lock state. The second friction brake is placed within the radius of the first friction brake. A reduced size is accomplished and the final reduction gear unit can be reduced in length in the vehicle-transverse direction. Thus, a vehicle final reduction gear unit allowing a reduction in size can be provided.
