Abstract

PURPOSE:To make a spring mechanism into such one that is unnecessary to consider any service life due to fatigue and that has not any displacement component in a direction orthogonal with the load direction by setting up a hot superconductive material in the displacement direction of a permanent magnet connected to a shaft transmitting external force so as to be opposed to this permanent magnet. CONSTITUTION:When a movable part constituted of rods 3a, 3b, and a permanent magnet 2 magnetized to both upper and lower parts is moved upward, the movable part receives downward force due to the positional relation between the permanent magnet 2 and hot superconductive materials 2a, 1c. On the other hand, when the movable part is moved downward, it receives the upward force conversely. That is to say, it is no more than motion of mass fixed to a compressive tension spring. In addition, if each material of the permanent magnet 2 and a hot superconductive material 1b is uniform with each other, the permanent magnet 2 in a movable part comes to receive the uniform radial additive force from this hot superconductive material 1b to be turned to an outer cylinder in consequence, so that vertical motion in the state that a uniform peripheral clearance is always kept up is made possible.
