PROBLEM TO BE SOLVED: To provide a lubricating oil circulation structure for a transmission, which reduces scraping loss by preventing lubricating oil from becoming rotational resistance of a differential ring gear.SOLUTION: A first storage part 3g storing the lubricating oil scraped by the rotation of the differential ring gear is provided at a gap part facing the outer periphery of the differential ring gear 8a of a differential mechanism 8 in a differential chamber B, a second storage part 3h is provided in a bottom face gap part in a mission chamber A, a communication hole 3i sending the lubricating oil in the first storage part 3g to the second storage part 3h along a separating wall 3a is provided in the first storage part 3g, and a return passage 3j returning the lubricating oil in the second storage part 3h into the differential chamber B is provided in the second storage part 3h. |
