PURPOSE:To technically simply manufacture a driving mechanism, to reduce its cost and to stably use it for a long period of time. CONSTITUTION:A high temperature superconductor 2 is placed on a lower inner surface in a horizontal conduit 1, an upper permanent magnet 3a is placed on an outer upper surface of the conduit 1, a lower permanent magnet 3b is disposed under the outer lower surface of the conduit 1, and the magnet 3b is not brought into contact with the outer lower surface of the conduit. Then, the superconductor 2 is cooled to a critical temperature or lower by refrigerant, and then the magnet 3b is raised toward the outer lower surface of the conduit. As it is raised, the magnetized superconductor 2 is repelled to be brought into noncontact with the conduit, and the magnet 3a is also repelled to be brought into noncontact with the conduit or into contact in the degree to be smoothly moved. Then, the magnet 3b is moved in parallel with the conduit, and the magnet 3a is moved in parallel with the conduit in noncontact with the conduit in response to the movement of the magnet 3b. |
