1. A driving force adjusting device comprising a pair of electric motors that drives left and right wheels of a vehicle, a differential mechanism that provides the left and right wheels with a torque difference, and left and right drive shafts that transmit driving force from the differential mechanism to the left and right wheels, the driving force adjusting device having four elements and two degree of freedom, wherein
inertia moments on paths from the pair of electric motors to the left and right wheels are set to values such that a resonance frequency of the driving force adjusting device when the vehicle is turning comes to be larger than a yaw resonance frequency of the vehicle.
