To provide a lubrication structure for a hybrid vehicle driving device, capable of improving the performance of lubricating a transmission mechanism and a speed reduction mechanism by increasing the amount of lubricating oil to be supplied to the transmission mechanism and the speed reduction mechanism, thus improving the reliability of the transmission mechanism and the speed reduction mechanism.SOLUTION: In a driving device 4, a speed reduction mechanism 33 is installed with an input shaft 34, a first intermediate shaft 35 and a second intermediate shaft 36 separating from one another in the vertical direction so as to protrude upward relative to a transmission mechanism 40. A transmission case 5 includes an oil gutter 66 for trapping lubricating oil scraped up by a final driven gear and supplying it to the transmission mechanism 40. The oil gutter 66 is installed at the lower part of the speed reduction mechanism 33 so as to trap the lubricating oil scattering and flowing down from the speed reduction mechanism 33, and has a pipe part for supplying the lubricating oil into an oil distribution space of a bearing support part supporting the second intermediate shaft 36 located at the lowest position.SELECTED DRAWING: Figure 4
【課題】変速機構と減速機構に供給される潤滑油の量を増やして変速機構と減速機構の潤滑性能を向上でき、変速機構と減速機構の信頼性を向上できるハイブリッド車両用駆動装置の潤滑構造を提供すること。【解決手段】駆動装置4において、減速機構33は、変速機構40に対して上方に突出するように入力軸34、第1の中間軸35および第2の中間軸36が上下方向に離れて設置されており、変速機ケース5は、ファイナルドリブンギヤによって掻き上げられた潤滑油を捕捉し、変速機構40に供給するオイルガター66を備えている。オイルガター66は、減速機構33から飛散して流下する潤滑油を捕捉するように減速機構33の下部に設置されており、最下位に位置する第2の中間軸36を支持する軸受保持部のオイル流通空間に潤滑油を供給するパイプ部を有する。【選択図】図4
