PROBLEM TO BE SOLVED: To provide an oil pump device of a transmission capable of enhancing rigidity of the whole case of the transmission mounted with the oil pump device therein and surely suppressing noise and vibration caused by the oil pump device, with a simple structure.SOLUTION: A transmission 3 is driven by rotation of an input shaft 41 into which power of an engine is input. The transmission includes: a housing case 21 which is connected to the engine in an axial direction of the input shaft 41; a left case 22 which is connected to the housing case 21 in the axial direction; and a middle plate 13 disposed in a direction orthogonal to the axial direction in at least either the housing case 21 or the left case 22. The middle plate 13 is fastened to the left case 22. An oil pump device 14 has an oil pump case 51, and the oil pump case 51 is fastened to the middle plate 13.SELECTED DRAWING: Figure 3 |
