[Challenge] There is no means for constraining the sphere seismic isolation bearing device using a multiple sphere of conventional, it becomes seismic isolation impossible sphere is dissipated in the rolling board outside vertical motion external force is exerted, spheres such as wind acts on the normal times more there is a drawback that swings. Slip the ball does not swing in the normal state sphere without dissipation, to provide a steel ball bearing composite seismic isolation devices. [MEANS FOR SOLVING PROBLEMS] The upper surface of the upper rolling disc table 2 which is made of a non-magnetic body having a predetermined plate thickness rigid to form the permanent magnet mounting incubation cabinet 3, yoke of using 2 times the diameter of the steel balls 9 to be used for the distance is placed a square bar magnet 11a with 12a on the entire surface shape, the entire circumference edge outside of the disc table 2 by providing a Wanen annular chamber wall plate 6 to form a steel ball retention chamber and moving path 5, further wall panel 6 outside the sliding plate 15 with an annular slide body 14, and erected under Utatedo-ban 1 top, excised the entire upper surface above the rolling surface 7 is below Utatedo-ban 1 opposed to the normal time, with little depth is to form a steel ball non-contact surface 18, is adsorbed the steel ball 9 of the appropriate number of the upper part or lower part of the rolling surface 7.
