To provide a damper that has a reduced leakage magnetic flux to the outside while being configured to be small-sized and has damping force that acts on only one direction.SOLUTION: A damper 101 includes: a movable element 102 formed of a conductor into a cylindrical shape; a magnetic flux generating part 103 which is arranged inside the movable element, of which end on a first side in a direction of an axis line O1 of the movable element has polarity of a first polar and of which end on a second side in a direction of the axis line has polarity of a second polar different from the first polar; and a yoke 104 formed of a soft magnetic material into a bottomed cylindrical shape, part of which being disposed on a radial outside of the movable element.SELECTED DRAWING: Figure 3
【課題】小型に構成しながら外部への漏洩磁束を小さくし、減衰力を1方向のみに作用させたダンパを提供する。【解決手段】ダンパ101は、導体で筒状に形成された可動子102と、可動子の内側に配置され、可動子の軸線O1方向の第1側の端部が第1極の極性を有するとともに、軸線方向の第2側の端部が、第1極とは異なる第2極の極性を有する磁束発生部103と、軟磁性体材料で有底筒状に形成され、一部が可動子の径方向外側に配置されたヨーク104と、を備える。【選択図】図3
