Abstract

A differential device is provided with: an input case having an axially directed end face; a differential gear set with side gears allowing a differential motion therebetween; dog teeth toothed toward the end face on an output case; a clutch structure engageable with the dog teeth and so structured as to couple the output case or the second side gear with the input case when engaged; an axially movable clutch member including an internal end and an external end exposed to the exterior; an axially movable armature including a magnetic material and in contact with the external end; a solenoid supported away from the end face, the solenoid generating a magnetic flux to attract the armature and, via the clutch member, set the clutch structure in mesh with the dog teeth; and a spring biasing the clutch member in a contrary direction.
