In a system including four electromagnetic absorbers for respective four vehicle wheels, motor coils of two respective electromagnetic absorbers disposed corresponding to two diagonally located wheels are connected forming a closed loop including the coils. A generated damping force magnitude can be made different between an instance directions of respective movements of the diagonally located two wheels with respect to the vehicle body are the same, and an instance the directions are opposite each other. Each electromagnetic absorber includes a resistor cooperating with the corresponding coil forming a closed loop, and selectively establishes: a connected state in which one of the four coils and any of the other three coils are connected to form a closed loop; and a non-connected state in which the one of the four coils is not connected to any other coil. An appropriate vibration suppressing action is exhibited with respect to a coupled motion.
