To provide a lubrication structure of a power transmission device which can supply an oil to a portion to be lubricated sufficiently for lubrication when a rotation number of a final gear is low and which has a relatively inexpensive and simple structure which does not use an expensive and complicated baffle plate.SOLUTION: A partition wall 3 which divides the interior of a case 2 into a gear chamber 4A and a motor chamber 4B is provided with: a through hole 3a allowing communication between the gear chamber 4A and the motor chamber 4B; and a gutter member 50 extending into the gear chamber 4A below the through hole 3a and including a tip 50a disposed above an oil storage part 40. An oil introduced from the motor chamber 4B into the gear chamber 4A through the through hole 3a of the partition wall 3 flows along the gutter member 50 and is guided into the oil storage part 40 to allow a larger amount of the oil to be stored in the oil storage part 40 which is provided at a wall part other than the partition wall 3 of the case 2 and does not contact with the partition wall 3.SELECTED DRAWING: Figure 8
【課題】ファイナルギヤの回転数が低い場合であっても、潤滑対象の部位に対して潤滑に十分なオイルを供給できるようにし、かつ、高額で複雑なバッフルプレートを使用することなく比較的に安価で簡素な構成の動力伝達装置の潤滑構造を提供する。【解決手段】ケース2内をギヤ室4Aとモータ室4Bとに分割する隔壁3には、ギヤ室4Aとモータ室4Bを連通する貫通孔3aと、貫通孔3aの下方においてギヤ室4A内に延出してオイル貯留部40の上方にその先端部50aが配置された樋部材50と、が設けられている。モータ室4Bから隔壁3の貫通孔3aを通ってギヤ室4Aに導入されたオイルが樋部材50を伝ってオイル貯留部40に導かれることで、ケース2の隔壁3ではない壁部に設けられて、かつ、隔壁3には接していないオイル貯留部40に対して、より多くのオイルを貯留させることができる。【選択図】図8
