<p><P>PROBLEM TO BE SOLVED: To provide a simply structured differential device wherein a dog clutch surely engages and disengagis without requiring a large actuator. Ž<P>SOLUTION: This differential device is provided with an outer differential case 203 which is rotated by inputting the drive force of an engine, and an inner differential case 41, which incorporates a differential mechanism 2057 for differentially distributing the drive force of the engine and is supported in the outer differential case 203 coaxially so as to be rotatable, a clutch member 43, which is arranged adjacent to the inner differential case 41 in its axial direction, is movable axially and rotates integrally with the outer differential case 203, dog clutches 41a and 43a, which are arranged between the inner differential case 41 and the clutch member 43 opposing to each other and mesh with each other so as to be engaged and disengaged by the axial movement of the clutch member 43, and an electronic drive means 61, which has a ring-like plunger 65 for moving the clutch member 53 so that the dog clutches 41a and 43a are engaged with and disengaged from each other and is arranged coaxially with an output shaft.
