能させるようにして使用される。(Technical background of the invention and its problems) A conventional air spring device is shown in FIG. 2. That is, in this device, an air chamber 3 is formed by a cylindrical hollow rubber body 1 whose upper end is closed and whose lower end is open, and a substrate 2 which closes the lower end of the rubber body. A boss portion 5 having a screw hole 4 for machine attachment is provided. In this device, compressed air is sealed into an air chamber 3 from a valve 6 attached to the side of a hollow rubber body 1, and a machine (not shown) is placed on a boss portion 5.
It is used so that the upper closed end surface 1a functions as a so-called diaphragm.

疲労を起こし、やがてそこに発生する亀裂が原因
で空気漏れが生じるという欠点がある。 However, in the conventional device, the upper closed end surface 1a of the hollow rubber body is inflated by the air pressure in the air chamber 3 as shown in FIG. The drawback is that the deformation causes fatigue, and eventually cracks that form there cause air leaks.
なお、中空ゴム体の閉塞端１ａの肉厚を厚くす

ことはできない。 Incidentally, it is possible to reduce the occurrence of the above-mentioned cracks by increasing the wall thickness of the closed end 1a of the hollow rubber body, but on the other hand, this will deteriorate the spring characteristics, so this is not a good improvement. It cannot be called a strategy.

In FIG. 1, a cylindrical main body 1 with one end closed and the other end open, and a substrate 2 closing the open end of the cylindrical main body 1 are removably connected via screw rings 7 and 8. One threaded ring 7 is fixed to the outer periphery of the open end of the cylindrical body 1, the other threaded ring 8 is fixed to the base plate 2, and both threaded rings 7, 8 are screwed together.
筒形本体１の閉塞端面に、機械取付用ねじ孔４

This air bag 9 is expandable and deflated, and comes into contact with the inner wall of the cylindrical body 1. A valve 6 passing through the cylindrical body 1 is attached to the air bag 9, so that air can be taken in and out from the outside of the cylindrical body 1 through the valve 6.

無とはほとんど無関係である。 When using the air spring device configured as described above, compressed air is sealed into the air bag 9 from the valve 6 to create the state shown in FIG. 1, and a machine (not shown) is placed on the boss portion 5. In the state shown in FIG. 1, the spring constant of the air bag 9 is significantly smaller than that of the cylindrical body 1. Therefore, the spring characteristics of the air spring device of the present invention are determined by the spring characteristics of the cylindrical body 1 and are almost unrelated to the presence or absence of the air bag 9.
空気袋９は基板２を筒形本体１から取り外すこ
