Abstract
A filtering device includes a filter tank, a first drum filter both ends of which are supported, and a cantilever second drum filter. A first end portion of the first drum filter is supported on a first sidewall of the filter tank. A second end portion of the first drum filter is supported on a second sidewall. An end portion of the second drum filter on the supported side is supported on the first sidewall. Between an end portion of the second drum filter on the non-supported side and the second sidewall, a communicating part is formed. A first jetting section jets a fluid against an outer circumferential surface of the first drum filter. A second jetting section is arranged in the vicinity of the second drum filter and jets the fluid against the second drum filter.
