Summary:PROBLEM TO BE SOLVED: To provide an oil pump mounting structure capable of disposing a transmission case without increasing weight, even if a separated shaft type oil pump and a manual shaft are disposed in the same space in the transmission case. SOLUTION: The oil pump 14 and the transmission case 20 are connected to two beams 26, 28, and oil passages 26b, 28c are formed in the beams 26, 28 to communicate a control valve unit 24 and the like to the oil pump 14. A parking manual shaft 44 is disposed between the beams 26, 28, so that a thick supporting wall for making the manual shaft 44 penetrate to the transmission case 20 side is unnecessary. Furthermore, the oil passages 26b, 28c are formed in the beams 26, 28, so that the layout of the oil pump 14 and the oil passages 26b, 28c which do not interfere with the manual shaft 44 is naturally achieved. Function regulating bending in an axially orthogonal direction of the manual shaft 44 can be added to the beams 26, 28, thereby solving the problem. COPYRIGHT: (C)2010,JPO&INPIT
