Abstract
In a differential for vehicles, a pair of side gears are received in a housing and coaxial with the housing. The pair of side gears are spline-connected with end portions of a pair of coaxial output shafts. The pair of side gears are meshed with each other through paired element gears. Each side gear has a protrusion of a reduced diameter to be inserted in a receiving recess of the housing. A primary thrust washer and a coned disk spring are interposed between a shoulder of each side gear and the housing. A secondary thrust washer is interposed between the protrusion of the side gear and the housing. With a distal end face of the protrusion of the side gear contacting the housing through the secondary thrust washer, a distance between the shoulder of the side gear and the inner surface of the housing is larger than a total thickness of the primary thrust washer and the coned disk spring.
