PROBLEM TO BE SOLVED: To provide a lubrication structure of a hybrid vehicle which can suppress an increase of an agitation loss which is generated when a vehicle speed is high.SOLUTION: A lubrication structure of a hybrid vehicle comprises a gear chamber G in which a planetary gear device 40 connected to an engine 10 and rotating electric machines 20, 30, and a differential device 50 to which power from the planetary gear device is transmitted are accommodated, and a motor chamber M which is partitioned by the gear chamber and a bulkhead B, and in which the rotating electric machines are accommodated. A lubricant at a gear chamber bottom part is scooped up by the rotation of a finish reduction gear 52 of the differential device arranged at a lower part of the gear chamber, and supplied to the planetary gear device. An outer gear 46b for transmitting power to the differential device is arranged at an external peripheral face, and a cylindrical output member 46 of the planetary gear device having an inner tooth gear 46a at an internal peripheral face is rotatably supported to the bulkhead B via a bearing 47a at its one end. Then, a communication hole 80 for making the gear chamber G and the motor chamber M communicate with each other is formed at a facing part Bo1 of the bulkhead B in the vicinity of an external peripheral end 47a1 of the bearing 47a.SELECTED DRAWING: Figure 2

    【課題】車速が高い場合に生じる攪拌損失の増大を抑制することのできるハイブリッド車両の潤滑構造を提供する。【解決手段】エンジン10及び回転電機20,30に接続される遊星歯車装置40と、遊星歯車装置からの動力が伝達される差動装置50と、が収容されるギヤ室G、およびギヤ室と隔壁Bによって隔てられて回転電機が収容されるモータ室Mを備え、ギヤ室下部に配置された差動装置の最終減速歯車52の回転によってギヤ室底部の潤滑油が掻き上げられることで遊星歯車装置に対して潤滑油が供給されるハイブリッド車両の潤滑構造において、差動装置に動力を伝達するための外歯歯車46bを外周面に有し、かつ内歯歯車46aを内周面に有する遊星歯車装置の円筒状の出力部材46は、その一端が軸受47aを介して回転可能に隔壁Bに支持されている。そして、軸受47aの外周端47a1近傍の隔壁Bの対面部Bo1には、ギヤ室Gとモータ室Mとを連通する連通孔80が設けられている。【選択図】図2
