To realize excellent lubrication even in a case when a liquid level of a lubricant is relatively inclined to a case, while reducing a storage amount of the lubricant in the case of a power transmission device.SOLUTION: A lubrication structure of a power transmission device has a recessed portion 102 on a vertical wall portion 101 on which a bearing 84 of a case 70 for housing a first gear 21 and a second gear 22 is disposed, and has a rib 103 axially projecting from an inclined surface portion 102b inclined from axial one side to the other side, from a front side in a rotating direction of the second gear toward a rear side from a bottom surface portion 102a of the recessed portion. A side end portion 103c of a projecting end portion 103a of the rib is inclined from the rear side in the rotating direction of the second gear to the front side as it goes from the axial other side to one side while inclined downward from the axial other side to one side, and an angular portion 103h between the rib and the inclined surface portion is inclined from the rear side in the rotating direction of the second gear to the front side as it goes from the axial other side to one side, while inclined downward from the axial other side to one side.SELECTED DRAWING: Figure 9

    【課題】動力伝達装置のケース内における潤滑油の貯留量の低減を図りつつ、潤滑油の液面がケースに対して相対的に傾斜する場合おいても良好な潤滑を実現する。【解決手段】動力伝達装置の潤滑構造は、第1ギヤ21と第2ギヤ22を収容するケース70の軸受84が配置された縦壁部101に、凹部102を備え、凹部の底面部102aから第2ギヤの回転方向前方側から後方側に向かって軸方向一方側から他方側に傾斜する傾斜面部102bから軸方向に突出するリブ103を有し、リブの突出端部103aの側端部103cは、軸方向他方側から一方側に向かって下方に傾斜しつつ軸方向他方側から一方側に向かうにつれて第2ギヤの回転方向後方側から前方側に傾斜し、リブと傾斜面部との角部103hは、軸方向他方側から一方側に向かって下方に傾斜しつつ、軸方向他方側から一方側に向かって第2ギヤの回転方向後方側から前方側に傾斜する。【選択図】図9
