PROBLEM TO BE SOLVED: To provide a filter device capable of easily replacing only a resin part, and improving recyclability.SOLUTION: A cover assembly includes a valve disposed on a lid member covering an opening end of a case, and the valve includes a substantially cylindrical first fitting face along a longitudinal direction of a filtering material contained in a filter element. A first end member disposed at a first end of the filtering material includes a second fitting face which the first fitting face is fitted to, and when the first fitting face is fitted to a second fitting face, the filter element is attached to the valve. The cover assembly is detachably attached to a case assembly having a substantially cylindrical case inside which the filter element is inserted, and an inner cylinder in a substantially cylindrical shape on which a large number of openings are formed.SELECTED DRAWING: Figure 2 |
