PROBLEM TO BE SOLVED: To solve a problem that in the field, such as nuclear power plant facilities and research facilities, or manufacturing facilities, producing contaminated gas containing hazardous materials which may have adverse effects on the human body, an air cleaning device having a complete airtight structure for cleaning and exhausting the contaminated gas without leaking the gas to the outside is used, however, the filter attachment/detachment work in the filter exchange is troublesome and takes a lot of troubles because of a complete airtight construction, and moreover the mechanism is complicated to improve air tightness of sealing in the attachment of the filter, and accordingly a preferred filter mounting structure is expected.SOLUTION: An air cleaning device is provided with a device body formed with a contaminated gas inlet, a treated gas exhaust outlet, and a filter exchange port 4. In the inside of the device body, there are provided a filter receiving surface and a partition plate. A filter mounting structure of the air cleaning device is provided with a pair of X-shaped supporting legs for vertically moving a filter cradle between the filter cradle mounting a filter and the partition plate, and also provided with a lever including an eccentric cam plate for sliding the supporting legs. |
