Abstract

An electric vehicle driving device includes a first motor, a second motor, a transmission device to which power of at least one of the first motor and the second motor is transmitted, and an output member that rotates with power output from the transmission device. A rotation axis of the first motor, a rotation axis of the second motor, and a rotation axis of the transmission device are arranged in parallel to a rotation axis of the output member. When seen from an axial direction parallel to the rotation axis of the output member, the rotation axis of the first motor is located on one side of a straight line passing through the rotation axis of the output member and the rotation axis of the transmission device and the rotation axis of the second motor is located on the other side of the straight line.
