Original Abstract Submitted
An electric drive device is applied to a vehicle having drive wheels and rotates the drive wheels about a rotation central axis extending in a horizontal direction to drive the vehicle. The electric drive device includes a drive unit provided on an underside of a base portion of the vehicle and having a motor and a transmission mechanism connected to the drive wheels, and a steering mechanism provided on the underside of the base portion and having a steering center shaft extending in a vertical direction. The steering mechanism supports the drive unit relative to the base portion so that the drive unit can rotate about a steering center shaft while maintaining a rotational central axis of the drive wheels in a horizontal state. A position of the steering center shaft is offset in the horizontal direction from a contact area of the drive wheels with a driving road surface.
