PURPOSE: To prevent the vibration of a winding machine from spreading to a building by providing superconductive magnets on a base of an elevator winding machine and a beam of the building respectively, and mounting the magnets so that their magnet poles may be repulsive to each other.
CONSTITUTION: A salient-pole 10 having a superconductive coil 11 is mounted on the lower side of a base 6 of an elevator winding machine. In addition to that, a salient-pole 12 having a superconductive coil 13 is mounted at a position opposite to the salient-pole 10 on a beam 7 forming a structural body 8 of a building, and a coil 11 is turned on so that the polarities of the salient-poles 10, 12 may be repulsive to each other. Thus the winding machine 6 supported through air gap can prevent its vibration from spreading to the building.
