PURPOSE:To mitigate a shock in the state that no vibration term exists by using an electromagnet for at least one of magnets faced to each other and mitigating the shock from the outside with the force reacting between the magnets via the preset control mechanism of the conducting current. CONSTITUTION:An electromagnet 11 is used for at least one of magnets 1 faced to each other, and a control mechanism controlling I in proportion to -x'.1/F(x) is provided, where (x) is the distance between centers of opposite magnets 1 and 11, I is the current flowing through the electromagnet 11, I.F(x) is the force reacting between opposite magnets 1 and 11, F(x) is the function of (x), and x' is the differentiated quantity of (x) by time. A shock applied from the outside is mitigated by the force reacting between the magnets 1 and 11. When both magnets 1 and 11 tend to be separated in distance by the shock force from the outside, a suction force is applied against it, when they tend to be moved nearer on the contrary, a repulsion force is applied against it, because the current I is controlled in proportion to -x'.1/F(x). |
