To provide an inverter device A for an electric vehicle, which is configured so that oscillation of a transformer 2 can be stopped in a housing 1 while being reduced in size and in weight.SOLUTION: A receiving piece 91 extending to approach a side wall part 12 of an enclosure 1 positioned at a lower end part 22 side of a transformer 2 is provided in at least either of a pair of lower side surface parts 22a opposing to each other in a vehicle width direction, in the lower end part 22 of the transformer 2. In the enclosure 1, an auxiliary wall part 100 is erected at a portion of a bottom wall part 13 positioned between the side wall part 12 and the receiving piece 91. The lower end part 22 of the transformer 2 is connected to the enclosure 1 through an oscillation stopper 200, under which a fixing piece 201 of the oscillation stopper 200 is fastened to the auxiliary wall part 100 of the enclosure 1, and a connecting piece 202 of the oscillation stopper 200 is fastened to the receiving piece 91 of the transformer 2, so that oscillation of the transformer 2 is stopped in the enclosure 1.SELECTED DRAWING: Figure 1

    【課題】電動車両用インバータ装置Aにおいて、筐体1内でのトランス2の振れ止めを、小型且つ軽量化を図りつつ実現する。【解決手段】トランス2の下端部22には、車幅方向に対向する一対の下部側面部22aの少なくとも一方に、トランス2の下端部22側に位置する筐体1の側壁部12に近づくようにのびる受け片91が設けられ、筐体1には、側壁部12と受け片91との間に位置する底壁部13の部分に、補助壁部100が立設され、振れ止め具200を介してトランス2の下端部22が筐体1に連結され、この連結状態では、振れ止め具200の固定片201が筐体1の補助壁部100に締結されると共に、振れ止め具200の接続片202がトランス2の受け片91に締結されて、トランス2が筐体1内で振れ止めされる。【選択図】図1
