    • An electromagnetic damper 100 according to an embodiment of the present invention includes a first tubular member 111, a second tubular member 121, a rod 123, a plurality of electromagnetic coils 113, permanent magnets 125, and a short circuit 130. The second tubular member 121 is mounted on the first tubular member 111 and is configured to be capable of being relatively displaced in one axis direction with respect to the first tubular member 111. The rod 123 extends in the one axis direction and is, at one end, fixed to the second tubular member 121. The plurality of electromagnetic coils 113 are disposed in either one of an inside of the first tubular member 111 or the rod 123. The permanent magnet generates induced electromotive force in the plurality of electromagnetic coils 113 by relative displacement with respect to the plurality of electromagnetic coils 113 and are disposed in the other of the inside of the first tubular member 111 or the rod 123. The short circuit 130 is connected to the plurality of electromagnetic coils 113 and shorts the terminals of the plurality of electromagnetic coils 113 to each other.
