<p>A construction having a nonlinear damping plus spring characteristics is such that at least two permanent magnets (2, 4) are spaced from each other and a geometric dimension between the permanent magnets is changed by an input and output by a mechanism in a stroke of movement or external force (1) to be converted into a repulsive force in a system of movement to thereby make a repulsive force on an output side of an equilibrium position of the two permanent magnets larger than a repulsive force on an input side or (2) to draw out an attenuation term of a magnetic spring.</p> |
