A coaxial drive device for driving a pair of axles capable of rotating around a first shaft is provided with: a motor coaxial with the first shaft; a differential which is coaxial with the first shaft, can rotate around the first shaft, and is provided with a differential gear set which outputs received torque to the pair of axles in a differential manner; an output shaft that passes through the motor, is driven by the motor to rotate around the first shaft, and has a through hole sized to allow one of the pair of axles to reach the differential from the outside; a transmission shaft that is rotatable about a second axis parallel to the first axis, meshes with both the output shaft and the differential, and transmits the torque from the motor to the differential; a clutch disposed between the motor and the differential gear set to restrict differential motion of the differential gear set, or disposed on the transmission shaft to detachably connect the output shaft and the differential; and an actuator that is disposed above the first shaft and that drives the clutch.
