PROBLEM TO BE SOLVED: To provide a transmission capable of inhibiting the efficiency deterioration of a driving force which results from lubrication without newly providing a power source.SOLUTION: A differential gear 5 is disposed so that at least a part thereof is immersed in an oil reservoir of a lubrication oil accumulated in a transmission case 2. In the transmission case 2, an oil reservoir part 9 for accumulating the lubrication oil scattered by the differential gear 5, an impeller 10 which is rotated by the scattered lubrication oil hitting thereon, and a lubrication oil feeding mechanism 11 which utilizes a rotation force of the impeller 10 to feed the lubrication oil in the oil reservoir part 9 to the other end side in the transmission case 2 are provided. |
