To provide a lubrication structure for a hybrid vehicle driving device, capable of reliably lubricating a speed reduction mechanism even when the speed reduction mechanism is installed above a transmission mechanism, thus improving the reliability of 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 pipe 48 for supplying lubricating oil to the upper part of the speed reduction mechanism 33, and a guide groove for supplying the lubricating oil supplied from the oil pipe 48 into an oil distribution space in a bearing holding part.SELECTED DRAWING: Figure 4

    【課題】減速機構が変速機構に対して上方に設置された場合であっても、減速機構を確実に潤滑でき、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、減速機構33の上部に潤滑油を供給するオイルパイプ48と、オイルパイプ48から供給される潤滑油を軸受保持部の内部のオイル流通空間に供給するガイド溝とを有する。【選択図】図4
