To inhibit interference between an inverter case installed in a vehicle and other components in a thickness direction, while securing the area required for a circuit substrate of an inverter, in an axle driving device with an electric motor for a work vehicle.SOLUTION: An axle driving device 41 with an electric motor for a work vehicle is used for a work vehicle in which left and right wheels are driven by a common electric motor. An axle case 42 for accommodating an input axis, a gear mechanism, a first axle and a second axle includes an input axis side portion 45. One side of a motor case 61 is fixed to the input axis side portion 45. On an end surface or an outer peripheral surface of the other end side of the motor case 61, an inverter case 80 is fixed. The inverter case 80 has a flat shape in which the maximum thickness is smaller than the maximum length in a first direction, and is extended to one side in a longer direction being the first direction separated from the motor case 61, and a terminal part projects from the outer peripheral surface of the motor case 61 to the outside in a radial direction.SELECTED DRAWING: Figure 2

    【課題】作業車両用電気モータ付き車軸駆動装置において、インバータの回路基板の必要な面積を確保しながら、車両に設置されたインバータケースの厚み方向における他の部品との干渉を防止する。【解決手段】作業車両用電気モータ付き車軸駆動装置41は、左右の車輪が共通の電気モータで駆動される作業車両に用いられる。入力軸と歯車機構と第1車軸及び第2車軸とを収容する車軸ケース42は、入力軸側部分45を有する。モータケース61の一方側は、入力軸側部分45に固定される。モータケース61の他端側の端面または外周面には、インバータケース80が固定される。インバータケース80は最大厚みが第1方向の最大長さより小さい扁平形状であり、モータケース61から離れる第1方向である長手方向の一方側に延伸させるとともに末端部分は、モータケース61の外周面から径方向外側に突出している。【選択図】図2
