To inhibit interference between an inverter case and other components of a vehicle side, in an axle driving device with electric motors for a work vehicle, in a constitution having an inverter which is thin and whose first direction length being orthogonal to a thickness direction is large.SOLUTION: An axle driving device with electric motors for a work vehicle is used for a work vehicle in which left and right wheels are driven by a pair of electric motors independent of and different from each other. An axle case for accommodating an input axis, a gear mechanism and an axle includes an input axis side portion and an axle side portion of both sides in a longitudinal direction. One side of a motor case is fixed to the input axis side portion. On an end surface or an outer peripheral surface of the other end side of the motor case, an inverter case is fixed. The inverter case 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, and a terminal portion is arranged in a space on an opposite side of an axle projection side being a space facing the axle side portion.SELECTED DRAWING: Figure 3

    【課題】作業車両用電気モータ付き車軸駆動装置において、薄型で厚み方向に直交する第1方向長さが大きいインバータを持つ構成で、インバータケースと車両側の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は、左右の車輪が互いに独立して異なる電気モータの一対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車軸とを収容する車軸ケースは、前後方向両側の入力軸側部分と車軸側部分とを有する。モータケースの一方側は、入力軸側部分に固定される。モータケースの他端側の端面または外周面には、インバータケースが固定される。インバータケースは最大厚みが第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、車軸側部分に面する空間であって車軸突出側とは反対側の空間に配置される。【選択図】図3
