PROBLEM TO BE SOLVED: To provide an electromagnetic damper capable of improving a vibration attenuation characteristic.SOLUTION: An electromagnetic damper 10 includes a screw shaft 32, a first nut 52, and a second nut 54. In the screw shaft 32, formed are a first screw groove 120, and a second screw groove 122 having a different lead from that of the first screw groove 120 and arranged without crossing the first screw groove 120 so that their phases are deviated from each other. The first nut 52 is screwed into a screw shaft 32 so as to correspond to the first screw groove 120, and the second nut 54 is screwed into the screw shaft 32 so as to correspond to the second screw groove 122. The electromagnetic damper 10 further includes a relative rotation regulation member 80 for regulating change of the relative rotation angle of the first nut 52 and the second nut 54.SELECTED DRAWING: Figure 4

    【課題】振動減衰特性を向上可能な電磁ダンパを提供する。【解決手段】電磁ダンパ10は、ねじ軸32、第1ナット52及び第2ナット54を備える。ねじ軸32には、第1ねじ溝120と、第1ねじ溝120とリードが異なり且つ第1ねじ溝120と交差せずに位相をずらして配置される第2ねじ溝122とが形成される。第1ナット52は、第1ねじ溝120に対応してねじ軸32に螺合し、第2ナット54は、第2ねじ溝122に対応してねじ軸32に螺合する。電磁ダンパ10は、第1ナット52と第2ナット54との相対回転角度の変化を規制する相対回転規制部材80をさらに備える。【選択図】図4
