Abstract: There is provided an oil separating structure of an automatic transmission, which makes it difficult for an oil strainer of an oil pump to draw oil containing air bubbles. A baffle plate base separates a space around the oil strainer and a space around a driven sprocket as well as a final gear, and therefore, oil containing air bubbles formed as a result of agitation by the driven sprocket, chain, and final gear does not flow directly into the oil strainer. As a result, the oil strainer is unlikely to draw oil containing air bubbles.
