Become. In addition, since the damper device of the present invention is configured in a package type, there is no need to connect the dampers with each other at the installation location, thereby reducing the cost of on-site work.

According to a second aspect of the present invention, for example, as shown in FIG. 1 to FIG. 4 or FIG. 6, in the configuration of the first aspect, the four chambers 1, 2, 3, 4 The casing C is partitioned such that any two of the chambers are adjacent to each other. The second aspect of the invention basically has the same function and effect as the first aspect of the invention, but has the following effect. That is, since the four chambers can be compactly assembled to prevent the generation of an extra space in the casing, the space occupied by the damper device is further reduced.

According to the invention of claim 3, for example, as shown in FIG. 1 to FIG. 4 or FIG.
The following configuration is added to the configuration of the above. The first room 1
And the third chamber 3 are partitioned by a first partition plate 21, the first damper 11 is provided on the first partition plate 21, and the second chamber 2 and the fourth chamber 4 are separated from each other. Partitioned by a second partition plate 22, the second damper 12 is provided on the second partition plate 22, and the third chamber 3 and the second chamber 2 are partitioned by a third partition plate 23. The third damper 13 is provided on the third partition plate 23, and the fourth
