PROBLEM TO BE SOLVED: To provide slide base isolation mechanism capable of reducing vibration of equipment (objects of aseismic base isolation) such as a shadowless lamp and a monitor attached to a ceiling at the time of an earthquake.SOLUTION: The mechanism includes: a support part 2 fixed to a beam material (building frame) 13 of a building 11; a ceiling material 3 which can slide on a top face of the support part 2; and a restoration material 6 composed of an elastic body which connects the building frame or the support part 2 with the ceiling material 3 and can restore displacement of the ceiling material 3 against the support part 2. The ceiling material 3 has a part exposed to the inside of an operation room 12 below the support part 2. |
