ABSTRACT:
A magnetic shield apparatus for shielding against magnetic leakage escaping from a cylindrical magnet unit having a columnar cavity, for generating a static magnetic field along the axial direction of the cavity, has a plurality of magnetic shield members which shield against magnetic leakage escaping from the magnet unit. The magnetic shield members are sequentially joined, with the joint portions of the magnetic shield members extending along the axial direction of the cavity, so as to surround the magnet unit. Casters are attached to each magnetic shield member. The magnetic shield members are fixed by bolts or the like so as to surround the magnet unit.
