Claim 0:
1. A lubricating structure for a vehicle power transmission device, comprising:
a case in which oil is stored at a bottom, wherein the case houses:
a transmission comprising a differential device, a final driven gear attached to a differential case of the differential device and rotatably supported on the case by a bearing, and a final drive gear meshing with the final driven gear; and
a transfer device comprising a transfer input gear that meshes with the final driven gear, wherein the transfer input gear meshes with the final driven gear above a rotation center of the final driven gear,

wherein the case comprises:
a first guide wall positioned above the bearing for guiding oil scraped up by the final drive gear or the transfer input gear to the differential device and the bearing;
an oil reservoir provided above the transfer input gear; and
a second guide wall provided below the oil reservoir and extending obliquely toward a central axis of the final driven gear;

wherein the lubricating structure further comprises:
an oil catch member that receives oil guided by the second guide wall and supplies the oil to the differential device and the bearing,
wherein the oil catch member comprises a first inclined part inclined so that a direction of the first guide wall is lowered, a notch formed at a position facing an opening formed in the differential case, and a groove for oil guiding that extends toward the bearing.
