The invention relates to a filter device (1), particularly an oil or fuel filter in a motor vehicle, having a filter housing cover (3) and a filter housing (2) which can be screwed together with said filter housing cover and in which a filter element (4), particularly a ring filter element, is arranged, wherein the filter element (4) comprises an upper end disk (5) and a lower end disk (6). It is essential to the invention that at least one radially protruding circumferential section (7, 7') is arranged on the upper end disk (5) and that a ring groove (8) designed complementarily to the circumferential section (7, 7') of the upper end disk (5) is provided on the filter housing cover (3). The at least one circumferential section (7, 7') of the upper end disk (5) engages in said ring groove and is guided in said ring groove in such a way that, in the event of a rotation of the filter housing cover (3), the at least one circumferential section (7, 7') slides in the ring groove (8) and at the same time effects an axial displacement of the filter element (4).
