PROBLEM TO BE SOLVED: To provide a structure which can secure lubrication even if a propeller shaft is stopped in rotation, in a differential device for a four-wheel drive vehicle for distributing power transmitted from the propeller shaft to left and right sub-drive wheels.SOLUTION: Since an oil slinger 138 which rotates together with an output shaft 70 is arranged at a sideway of a side bearing 104, a lubricant in a rear-wheel drive power distribution unit 34 is agitated by the rotation of the oil slinger 138, and the lubricant can be smoothly supplied to a side oil seal 154. By this constitution, even if a ring gear 68 is stopped in rotation, the lubrication of the side oil seal 154 can be secured.SELECTED DRAWING: Figure 3

    【課題】プロペラシャフトから伝達される動力を左右の副駆動輪に分配する4輪駆動車両用デファレンシャル装置において、プロペラシャフトが回転停止しても潤滑を確保できる構造を提供する。【解決手段】サイドベアリング104の側方には、出力軸70とともに回転するオイルスリンガ138が設けられることで、オイルスリンガ138の回転によって後輪用駆動力配分ユニット34内の潤滑油が攪拌され、サイドオイルシール154に潤滑油を供給することができる。これより、リングギヤ68が回転停止した場合であっても、サイドオイルシール154の潤滑を確保することができる。【選択図】図3
