PROBLEM TO BE SOLVED: To provide a differential device capable of reducing sliding resistance. SOLUTION: This differential device is provided with an outer differential gear case 31 rotated by receiving the driving force of an engine, an inner differential gear case 41 having a differential mechanism 57 differentially distributing the driving force of the engine in it and coaxially rotatably supported in the outer differential gear case 31, a clutch member 43 adjacently arranged in the axial direction of the inner differential gear case 41, movable in the axial direction, and rotated integrally with the outer differential gear case 31, dog clutches 41a and 43a provided on the opposite faces of the inner differential gear case 41 and the clutch member 43 and releasably meshed with each other by the axial movement of the clutch member 43, and an actuator means 65 moving the clutch member 43 in the axial direction to engage or release the dog clutches 41a and 43a. Centering sections 71 centering the inner differential gear case 41 from one of the inner differential gear case 41 side and the outer differential gear case 31 side to the other are provided at least at three or more positions in the peripheral direction.
