PROBLEM TO BE SOLVED: To provide a sliding support seismic isolator that can be well combined with a lamination rubber seismic isolator caused by occurrence of depression when the isolator is operated.SOLUTION: A slide supporting base isolation device 10 arranged between an upper structure 12 and a lower structure 14 of a structure comprises a slide plate 20 connected to the lower structure and extending substantially in a horizontal direction, and a sliding member 34 connected to the upper structure. The sliding plate 20 has an upper surface defining a sliding surface 24. The sliding member 34 has a lower surface defining a sliding contact surface 36 contacted with the sliding surface. When the sliding member 34 slips on the sliding surface 24 of the sliding plate 20, a relative motion of the upper structure 12 in respect to the lower structure 14 in a horizontal direction is allowed. The sliding surface 24 of the sliding plate 20 is substantially formed into a salient surface shape forming a partial spherical surface shape, thereby the sliding member 34 is displaced relatively in a horizontal direction in respect to the sliding plate 20 and moved away from its neutral position, the sliding member 34 is displaced in a vertical lower direction.SELECTED DRAWING: Figure 1
