A general air pump has a box-shaped casing made of resin or metal that covers the main body of the air pump that performs the pumping action, and anti-vibration supporting leg members made of elastic material such as rubber are attached near the four peripheral corners of the bottom surface of the casing. ing. The air pump is supported on the installation table by anti-vibration support leg members, so that vibrations generated by the air pump are not directly transmitted to the installation table.

エアポンプが故障するなどして、別の種類のエアポンプに交換することがあるが、交換するエアポンプのケーシングが大型である場合には、防振支持脚部材が設置台の設置面の縁よりも外側位置となり当該防振支持脚部材を設置面上に適切に載置することができない場合が生じる。 When the air pump breaks down, it may be replaced with a different type of air pump. If the casing of the air pump to be replaced is large, the anti-vibration support leg member should be outside the edge of the installation surface of the installation table. Therefore, there may be a case where the anti-vibration supporting leg member cannot be properly placed on the installation surface.

振動を生じる機器を、防振作用を伴いながら支持する部材としては例えば特許文献１及び特許文献２に開示されるようなものがあるが、いずれも上述のエアポンプの問題を解消するようなものではない。 For example, Patent Documents 1 and 2 disclose a member that supports a device that generates vibration while providing vibration isolation. do not have.
