In a bearing device for a rotating electric machine for a vehicle, in which a labyrinth part with a small gap is formed between the stator side component and the rotor side component in multiple stages, the outer side component is provided between the stator side component and the rotor side component. An annular waterway is formed in the circumferential direction between the labyrinth part that opens to the inner side of the bearing and the labyrinth part that communicates with the inside of the bearing, and the stator side component is penetrated from the lowest part of the annular waterway. A bearing device for a rotating electrical machine for a vehicle, characterized in that a drainage channel leading to the outside is formed, and a backwater prevention member for preventing water from entering from the outside is provided in the drainage channel. (2) The bearing device for a rotating electric machine for a vehicle according to claim 1, wherein the backwater prevention member is an opening/closing lid such as a check valve. (3) The bearing device for a rotating electrical machine for a vehicle according to claim 1, wherein the backwater prevention member is a plurality of cutting boards protruding into a drainage channel.
