２項いずれか記載の免震・防振装置。[Scope of Claim for Utility Model Registration] (1) In a seismic isolation/vibration isolator formed to allow relative displacement in the horizontal direction between a fixed side and a movable side, the fixed side is connected to the fixed side. A conical recess is formed on the upper surface of the member, and a large diameter steel ball is rotatably held at the center of the lower end of the movable side member connected to the upper movable side on the upper surface of the conical recess. An adjustment member that adjusts the gap formed between the lower end surface of the movable side member and the upper surface of the conical recess that it faces is movable up and down on the outer periphery of the lower end of the movable side member, which is adjacent to the movable side member. A seismic isolation/vibration isolating device, characterized in that the lower end of the adjustment member is present in high viscosity lubricating oil disposed on the upper surface of the conical recess. (2) The seismic isolation/vibration isolating device according to claim 1, wherein the conical recess is formed so that the center of its upper surface has the same curvature as that of a large diameter steel ball. (3) The movable side member has a large number of small-diameter steel balls inside, and a large-diameter steel ball located below is adjacent to the large number of steel balls. The seismic isolation/vibration isolating device described in any of paragraph 2.
