Abstract: The disclosure provides a lubricating structure for a vehicle power transmission device that may effectively lubricate a transfer device and a differential device without increasing the amount of oil. The lubricating structure includes: a first guide wall positioned above a bearing; a second guide wall provided below an oil reservoir and extending toward a central axis of a final driven gear; and an oil catch member that receives oil guided by the second guide wall and supplies the oil to a differential device and the bearing. The oil catch member includes 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 a differential case, and a groove for oil guiding that extends toward the bearing.
