Abstract
Provided is a lubricating fluid supply structure of a power transmission device capable of stably supplying a lubricating fluid to a built-in part to which the lubricating fluid is supplied with a high priority. A supply pipe (64a) includes a first main pipe line (L1) connected to a priority part, a second main pipe line (L2) connected to a non-priority part, and an intermediate pipe line (LM) connecting the first main pipe line (L1) and the second main pipe line (L2) to each other. A first height (H1) of a connection part of the first main pipe line (L1) connected to the intermediate pipe line (LM) is lower than a second height (H2) located at the highest position in a flow path bottom surface of the intermediate pipe line (LM).
