VIBRATION ISOLATION DEVICE
Document Type and Number:
Japanese Patent JP2015010625
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a vibration isolation in which sprung displacement is suppressed without changing a sprung thing.SOLUTION: A clamping device 11 disposed between a base 5 and a surface plate 9 includes: a portal type regulation member 35; a bolt 39 extending downward from a point corresponding to the regulation member 35 of a surface plate 9, and penetrating through a through-hole formed on a top wall part 35a of the regulation member 35; a pair of nuts 41, 43 screwed to the bolt 39 in the upper and lower sides of the top wall part 35a; and a helical compression spring 45 surrounding the bolt 39 between the top wall part 35a and the lower side nut 43 and biasing downward the nut 43 of the lower side. While the nuts 41, 43 are separated, the helical compression spring 45 biases downward the nut 43 of the lower side and draws out the surface plate 9 downward, and thereby the air pressure of an air spring is increased.
