PROBLEM TO BE SOLVED: To provide an isolation system which is superior on an isolating action and a damping action by making rolling motions and sliding motions in a single system and can cope with all directional vibrations in a simple structure and is a structure not blocking an isolating function. SOLUTION: The isolation system comprises an upper member 2 fixed on an upper structure 1, in which a curved surface section 2a with a concave internal surface is formed, a lower member 4 which is supported on a base member 1, in which an internal surface side 4a being high at a central part and being low at a peripheral part is formed on a tapered flat surface, and a rolling member 5 having a vertically-symmetrical convex curved surface section 5a which intervenes between the upper member 2 and lower member 4. An internal surface of the upper member 4 is formed by the curved surface section 4a and a flat plate section 4b smoothly continued with the curved surface section 4a. The rolling member 5 is formed in an approximately disk-shape as a whole shape, and has a structure having a central part 5a formed on the curved surface, a flat plate surface part 5c smoothly continued to the central part 5a, and a peripheral part 5c forming a vertical surface.
