An oil storage structure of a transmission case ensures the opening area of a suction port when an oil pan deforms. The storage structure for oil (OL) in the transmission case (1) is provided with an oil pan 5 that closes a lower opening 41 of the transmission case and forms an oil pool in a lower space inside the transmission case, and a strainer 6 having a suction port 66 for oil (OL) located in the oil pool. The suction port 66 for the oil (OL) is provided so as to face a bottom wall portion 51 of the oil pan with a gap in between, and the bottom wall portion of the oil pan is provided with a protruding portion 56 protruding toward the suction port, with the protruding portion being formed in a direction across the suction port as viewed from the bottom wall portion. 一种变速箱的油贮存结构，在油盘变形时，确保吸入口的开口面积。变速箱(1)的油(OL)的贮存结构具备：将变速箱(1)的下部开口(41)堵塞，在变速箱(1)内的下部的空间形成油积存部的油盘(5)；使油(OL)的吸入口(66)位于油积存部的滤油器(6)。油(OL)的吸入口(66)与油盘(5)的底壁部(51)隔开间隔而相对设置。在油盘(5)的底壁部(51)形成有向吸入口(66)侧突出的凸部(56)，该凸部(56)从底壁部(51)侧观察形成在横穿吸入口(66)的方向。
