摘要： PROBLEM TO BE SOLVED: To provide a base isolation device, ensuring smooth operation of a rolling seal air spring used as a longer period means while enlarging an air chamber thereof. SOLUTION: The base isolation device comprises an inside member protruded upward from a base, an outside member covering the upper end of the inside member, and a rolling seal member for sealing the inside member from the outside member while allowing relative movement therebetween. For equalizing the peripheral length of an inner peripheral portion of the rolling seal member to that of an outer peripheral portion thereof, an uneven portion is formed on the outer periphery of the inside member to equalize the outer peripheral length thereof to the inner peripheral length of the outside member.

摘要： PROBLEM TO BE SOLVED: To obtain a sufficient damping effect by supporting with a hinge in a rotatable manner either lower end portion of a lower stair portion or upper end portion of the upper stair portion, and then supporting other end portion in a movable manner to the main structure side thereby providing a vibration absorbing mechanism. SOLUTION: An upper end portion 13a of an upper stair 13 is supported by a main structural portion 14 with a hinge in a rotatable manner through a rubber bush 15 as a rotatable hinge portion equipped with a center shaft 15a, an outer cylinder 15b and a rubber 15c. Further, the lower end portion 11a of the lower stair 11 is supported by the main structural portion 14 in a horizontally movable manner through a slip member 16 laminated with a steel plate, rubber sheet and resin board as a movable supporting portion. And a vibration absorbing mechanism 17 equipped with a coil spring 17a and damper 17b is arranged. Next, when a person walks the stair 10 in the up or down direction, the change in the load causes a vibration f1 in up and down direction, this up-down vibration f1 is converted to rotating vibration f2 around the bush 15 as the center, and the vibration f2 is absorbed by a vibration absorbing mechanism 17. Thus, this mechanism is able to sufficiently maintain the damping effect against weight change or secular change.
