To provide a vehicle transmission capable of consolidating a torque converter, a valve body and an oil pump where oil flows therethrough in one case and simplifying a transmission case which has an oil passage communicating the valve body with the oil pump.SOLUTION: A transmission case 4 comprises a front case 6 which rotatably supports a turbine shaft 11, and includes a bulkhead 31 extending in a shaft direction of the turbine shaft 11 so as to separate an inner space of the transmission case into a torque converter chamber 32 storing a torque converter 10 and a clutch chamber 33 storing a friction clutch 17. A valve body 61 is overlapped with an oil pump 12 in the shaft direction of the turbine shaft 11 and installed on an outer peripheral lower face 55a of a bottom wall 55 of the front case 6 positioned below the bulkhead 31. The bulkhead 31 has an oil passage which communicates the valve body 61 with the oil pump 12.SELECTED DRAWING: Figure 3

    【課題】オイルが流れるトルクコンバータ、バルブボディおよびオイルポンプを1つのケースに集約でき、バルブボディとオイルポンプを連通する油路を有する変速機ケースを簡素化できる車両用変速機を提供すること。【解決手段】変速機ケース4は、内部の空間を、トルクコンバータ10を収容するトルコン室32と、摩擦クラッチ17を収容するクラッチ室33とに仕切るようにタービン軸11の軸方向に延びる隔壁31を有し、タービン軸11を回転自在に支持するフロントケース6を備えている。バルブボディ61は、タービン軸11の軸方向でオイルポンプ12と重なり、かつ、隔壁31の下方に位置するフロントケース6の底壁55の外周下面55aに取付けられており、隔壁31は、バルブボディ61とオイルポンプ12とを連通する油路を有する。【選択図】図3
