Abstract

A filter device has a filter housing (1) receiving a filter element (11) defining a longitudinal axis and being in the form of a filter cartridge. An end cap (19) forms an enclosure for the relevant end rim of the filter material (23, 25). The end cap fixes the position of the filter element (11) in its functional position by being on an element receiver (13) that interacts with the bottom part (7) of the filter housing (1). The element receiver (13) and the assigned end cap (19) of the filter element (11), on their parts (17 and 15) coming into engagement with one another in the functional position of the filter element are provided with shaped irregularities matched to one another to enable the engagement in a positional relationship directed towards one another.
