Abstract
In a bi-directional overrunning clutched differential unit, a pair of coaxial hubs are relatively unrotatably fitted on respective coaxial output shafts, and are relatively rotatably inserted into a cage holding rollers. A pair of second bearings journal a clutch housing disposed around the cage is diametrically larger than a pair of first bearings journaling the respective hubs, and are disposed between the first bearings in the axial direction of the output shafts. An axial end portion of the cage and the second bearing on the same axial side are distant from the first bearing on the same axial side so as to have a space where a friction mechanism for applying a frictional rotation resistance onto the cage is disposed.
