PROBLEM TO BE SOLVED: To provide a differential device which prevents a full-differential state of a differential gear device at disconnection for disconnecting a power transmission member from a sub-drive wheel, and improves a disconnection effect compared with a conventional technology.SOLUTION: At disconnection for disconnecting a propeller shaft 28 from a rear wheel 16 in a two-wheel drive state, since external peripheral engagement teeth 76a of a movable sleeve 76 which are fit to an internal peripheral side of a first protrusion 60b of a different case 60 by a second actuator 80 so as to be movable and power-transmittable in a rotation axial line C2 direction are moved to a position in which the engagement teeth are not engaged with internal peripheral engagement teeth 58c of a ring gear 58, and the ring gear 58 and the differential case 60 are separated from each other, a disconnection effect for disconnecting the propeller shaft 28 from the rear wheel 16 is improved compared with a differential device in which a full-differential state of the differential gear device 64 is prevented at the disconnection, and a conventional control coupling is used therein.SELECTED DRAWING: Figure 2

    【課題】動力伝達部材を副駆動輪から切り離すディスコネクト時において、差動歯車装置の全差動状態を防止し且つ従来に比較してディスコネクト効果を向上させるディファレンシャル装置を提供する。【解決手段】2輪駆動状態においてプロペラシャフト28を後輪16から切り離すディスコネクト時には、第2アクチュエータ80によって、デフケース60の第1突部60bの内周側に回転軸線C2方向に移動可能且つ動力伝達可能に嵌め合わされた可動スリーブ76の外周噛合歯76aが、リングギヤ58の内周噛合歯58cと噛み合わない位置へ移動し、リングギヤ58とデフケース60との間が切り離されるので、ディスコネクト時において差動歯車装置64の全差動状態が防止され且つ従来の制御カップリングが用いられるディファレンシャル装置に比較して後輪16からプロペラシャフト28を切り離すディスコネクト効果が向上させられる。【選択図】図2
