PROBLEM TO BE SOLVED: To provide a lubricating structure of a transmission, capable of restraining the supply volume of a lubricating oil to an end of a drive source side.SOLUTION: A lubricating structure of a transmission includes a hollow pump shaft 2a disposed inside a hollow rotation shaft 4 and for transmitting power of a vehicle drive source ENG to a pump 8, a middle-disposed member G3a disposed in the middle of the rotation shaft 4, an end-disposed member C1 disposed in the end of a side of an internal combustion engine ENG, and a lubricating-oil hole bored-disposed in the rotation shaft 4 and the pump shaft 2a and for supplying the lubricating oil to the members G3a and C1. The oil is supplied inside the pump shaft 2a from a side of the pump 8. The member C1 requires smaller supply volume of the oil than the member G3a. A difference part is provided on the inner peripheral face of the end of a side facing the pump 8 of the pump shaft 2a and positioned in a space between a middle lubricating-oil hole for supplying the oil to the member G3a and an end lubricating-oil hole for supplying the oil to the member C1. |
