うに搭載板ｌを空気ばねにて弾性支持している。Figures 1 to 3 are block diagrams for explaining an example of a conventional vibration isolator, with Figure 1 showing a plan view and Figure 2 a side view. Reference numeral 10 denotes a mounting plate on which precision equipment or precision machining equipment is mounted, and 10 indicates an air spring support device that elastically supports the mounting plate L using air pressure. Fig. 3 is an enlarged cross-sectional structure of the air spring support device. It shows. In Figure 3, 1■
1 is a member for receiving the mounting plate; 12 is an air spring chamber;
3 is an auxiliary air chamber, 14 is an air spring chamber 12 and an auxiliary air chamber 1
15 is an air supply valve,
16 is a diaphragm, and as is well known, the receiver is used by placing a mounting plate 1 on the member ti and mounting a precision instrument or a precision processing machine on the north side of the mounting plate l. At this time, the mounting plate 1 is elastically supported by air springs so that vibrations from the outside are not transmitted to the precision equipment, or vibrations from the precision machine are not transmitted to the outside.

の問題があった。Therefore, when a single air spring support device is used in a vibration isolating device such as 14, since the member 11 of the receiver is suspended by the diaphragm 16, the member 11 of the receiver is very likely to tilt. Therefore, it is impossible to mount precision equipment or precision processing machines and float horizontally. Therefore, in the conventional device, at least three air spring support devices are used (four are used in the illustrated example).
Thereby, the mounting plate 1 is maintained horizontally. Therefore, in the conventional device, at least three or more air spring support devices are used, which results in high cost.Also, each air spring support device must be arranged at a predetermined interval, which requires a large space. There were problems such as the need for
