Patent ID: 7969054

Claim:
A superconductivity utilizing support mechanism comprising: a superconductive coil; a ferromagnetic body; and an annular member that has a substantially U-shaped cross-section, the superconductive coil being arranged inside a U-shaped portion of the annular member, wherein the ferromagnetic body has a substantially ring shape or a substantially columnar shape, and is provided at its axially upper and lower ends and also at a position facing convex portions of the U-shaped portion of the annular member, with flange portions protruding radially outward, and one of the ferromagnetic body, so constituted as to slide in a direction of a center axis of the superconductive coil, and the superconductive coil, so constituted as to slide in a direction of the center axis thereof, being floated and supported relative to the other by axial magnetic attraction caused by a center plane of the superconductive coil and a center plane of the ferromagnetic body moving apart from each other.
