To provide an automatic transmission which can be downsized in a front and rear direction and in a vertical direction, and which can reduce vibration.SOLUTION: In an automatic transmission 1, a transmission case 2 has an opening on a frontward-falling inclined surface disposed at an upper part of the front end of the case, and the opening is formed on the transmission case 2 such that an opening face thereof is inclined diagonally upward from the front end of the transmission case 2 toward the rear end. The transmission case 2 has a first plate member 32 covering the opening, and a second plate member 39 disposed above the first plate member 32 and on the front end side of a transmission body 1A. A shift and select shaft is diagonally attached to the transmission case 2 so that the front end thereof is positioned below the lower end. The second plate member 39 has a planar vertical wall part 39A extending in the vertical direction at the front end of the transmission case 2, and a planar horizontal wall part 39B extending in the horizontal direction orthogonally from the vertical wall part 39A.SELECTED DRAWING: Figure 5 【課題】前後方向と上下方向にサイズを小型化でき、振動を低減することができる自動変速機を提供すること。【解決手段】自動変速機１において、変速機ケース２は、その前端部の上部に設けられた前下がりの傾斜面に開口部を有しており、開口部は、その開口面が変速機ケース２の前端部から後端部に向かって斜め上方に傾斜するように変速機ケース２に形成されている。変速機ケース２は、開口部を覆う第１プレート部材３２と、第１プレート部材３２の上方かつ変速機本体１Ａの前端部側に配置された第２プレート部材３９とを有している。シフトアンドセレクト軸は、その前端部が下端部よりも下方に位置するように、変速機ケース２に対して斜めに取り付けられている。第２プレート部材３９は、変速機ケース２の前端部において上下方向に延びる平面状の縦壁部３９Ａと、縦壁部３９Ａから直交して水平方向に延びる平面状の水平壁部３９Ｂとを有している。【選択図】図５
