Original Abstract Submitted
An electric vehicle includes a mechanical-electrical integrated unit constituted by a drive apparatus and an electric-power control apparatus that are housed in a same casing. The drive apparatus includes a first electric motor, a second electric motor and a transmission device. The electric-power control apparatus is configured to control an electric power transmitted and received by the first and second electric motors. The electric-power control apparatus and the drive apparatus are housed in upper and lower casing portion of the casing, respectively. The second electric motor includes a stator core that is provided with a plurality of fastened portions, such that one of the plurality of fastened portions is disposed in a position which overlaps the upper casing portion in a vertical direction of the vehicle and which is located on a front side of an axis of the second electric motor in a longitudinal direction of the vehicle.
