  "textContent": "An object of the present invention is to provide a structure that does not require a knuckle on the vehicle body side while improving the rotational accuracy of an input shaft of a speed reduction unit, increasing the durability of bearings, and suppressing the rotation noise of the bearings by improving the supporting structure of the input shaft of the speed reduction unit. In a drive device for an electric vehicle comprising: a speed reduction unit 12 including an input shaft 13 driven by an electric motor 11; a hub unit 15 rotationally driven by an output member 14 of the speed reduction unit 12; and a housing 16 accommodating the electric motor 11 and the speed reduction unit 12, wherein the input shaft 13 of the speed reduction unit 12 is supported by bearings 58, 59 provided at two locations in the axial direction, the drive device is configured such that the bearings 58, 59 provided at the two locations are both supported by the output member 14, and the housing 16 is provided with a suspension joining portion 27.",
