Abstract
A vehicular differential apparatus includes: a differential case; a first output portion in which a first coupling member and a first side gear mesh with each other via helical teeth; a second output portion in which a second coupling member and a second side gear mesh with each other via helical teeth; and a center washer 30 disposed between the first and second output portions. A clearance through which the first coupling member is movable in an axial direction between the center washer and the first sidewall portion is different in axial width from that through which the first side gear is movable in that direction therebetween. A clearance through which the second coupling member is movable in the axial direction between the center washer and the second sidewall portion is different in axial width from that through which the second side gear is movable in that direction therebetween.
