PROBLEM TO BE SOLVED: To solve the problem that large stress is generated at a supporting leg in the event of a large-scale earthquake. ! SOLUTION: A seismic isolator 1 includes an upper side leg member 3 and a lower side leg member 4. A pair of inclined planes 3b are formed at an end 3A of the upper side leg member 3. An end 4A of the lower side leg member 4 has a pair of connection support members 6 arranged so that the inclined planes 3b have surface contact with an abutting surface 6a, an attachment member 7 that swingably supports the connection support members 6, and an elastic member 8 that presses the connection support members 6 against the inclined planes 3b. !
