PROBLEM TO BE SOLVED: To provide a sub-derive wheel side differential unit of a four-wheel drive vehicle which prevents an all-differential state of a differential gear device at disconnection for disconnecting a power transmission member from a sub-drive wheel.SOLUTION: A variable sleeve 76 of a second clutch 32 is arranged between a cylindrical ring gear 58 and a cylinder shaft 60a of a differential case 60 of a differential gear device 64, and at disconnection for disconnecting a propeller shaft 28 from rear wheels 16, a clearance between the ring gear 58 and the differential case 60 is partitioned by a variable sleeve 76 of the second clutch 32. An all-differential state of the differential gear device 64 is thereby prevented at the disconnection.

    【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する4輪駆動車両の副駆動輪側ディファレンシャルユニットを提供する。【解決手段】円筒状のリングギヤ58と差動歯車装置64のデフケース60の円筒軸60aとの間に第2クラッチ32の可動スリーブ76が設けられ、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、その第2クラッチ32の可動スリーブ76によってリングギヤ58とデフケース60との間が切り離されるので、その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る。【選択図】図3
