<P>PROBLEM TO BE SOLVED: To provide a structure that does not require a knuckle on the vehicle-body side while improving the rotation accuracy of an input shaft of a speed reduction unit, increasing the durability of bearings, and reducing the rotational noise of the bearings by improving the supporting structure of the input shaft of the speed reduction unit. <P>SOLUTION: A drive device for an electric vehicle includes: a speed reduction unit 12 including an input shaft 13 that is driven by an electric motor 11; a hub unit 15 that is rotated and driven by an output member 14 of the speed reduction unit 12; and a housing 16 that houses the electric motor 11 and the speed reduction unit 12. 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 constructed such that: the bearings 58 and 59 provided at two locations are both supported by the output member 14; and the housing 16 is provided with a suspension coupling part 27. <P>COPYRIGHT: (C)2012,JPO&INPIT |
