Abstract
PURPOSE:To make it possible to carry out the opening and closing of fittings with less operational force by providing the superconductors and a magnet to separate the fittings from a body to the place opposed to the body and the fittings as an opening and closing device for an opening of a building. CONSTITUTION:A permanent magnet 8 is mounted at the upper side part of an opening of a body 1, and at the same time, the superconductor 9 in a superconductive state is mounted in opposition to each of a pair of arms 7 and 7 provided to the upper frame 3(a) of the frame doors 3 and 3. The frame door 3 is so constituted that it is separated from the body 1 side by Meissner effect to offset the magnetic line of force generated from the permanent magnet 8 by the magnetic line of force made from the current flowing to the surface of the superconductor 9 so that the magnetic line of force does not intrude into the superconductor 9. Accordingly, the opening and closing operation of the frame door 3 can be carried out with less operational force.
