摘要：
PROBLEM TO BE SOLVED: To provide an electromagnetic suspension device capable of improving a performance and durability.SOLUTION: An electromagnetic suspension device 1 includes a stator 2 disposed at a car body side and having a core 4 and coils 5A, 5B, 5C, a movable element 6 disposed at a wheel side and having an outer tube 7 and a permanent magnet 8, and a cylinder device 9 positioned inside of the stator 2 and the movable element 6 and disposed between the car body side and the wheel side. A rod 19 and an outer tube 7 of the cylinder device 9 are oscillatably connected through a connecting member 23 composed of an elastically-deformable elastic body. When lateral force is added, the connecting member 23 is elastically deformed, thus the outer tube 7 is oscillated to the rod 19, and contact of the coils 5A, 5B, 5C and the permanent magnet 8 can be suppressed.
