A damper system characterized by including: an electromagnetic damper which includes (a) an electromagnetic motor 46 configured to operate in association with an approaching motion of a sprung portion and an unsprung portion toward each other and a separating motion thereof away from each other (²) an external circuit 90 which is disposed outside the motor 46 and which includes (A) a first connection passage CFEB through which only a flow of a generated current of the motor 46 caused by the approaching motion is allowed to flow, (B) a second connection passage DFEA through which only a flow of a generated current of the motor 46 caused by the separating motion is allowed to flow, (C) a battery-device connection circuit for connecting the motor 46 and a battery device 120, and (D) battery-device-connection-circuit-current adjusters 108, 114, 122, 124 for adjusting an electric current that flows in the battery-device connection circuit; and an external-circuit controller 200 configured to control an electric current that flows in the motor 46 by controlling the external circuit 90. In the present damper system, a damping characteristic with respect to the approaching motion and a damping characteristic with respect to the separating motion can be easily made different from each other. Further, it is possible to control also a propulsive force to be generated by the electromagnetic damper. Accordingly, the present damper system has an excellent vibration damping characteristic.
