1. A filter element (10) for an air filtration device of a motor vehicle, comprising:
a frame (16) which at least partially surrounds a filter material (18) of the filter element (10), wherein the frame (16) comprises an elastically deformable front wall (20) which extends perpendicularly to an insertion direction (28) in which the filter element (10) is insertable in a receiving chamber (14) of a housing (12) of the air filtration device;
a fastening element (32), wherein a lid (34) of the air filtration device is fixable on the fastening element (32) and wherein the lid (34) is configured for closing the receiving chamber (14);
an insertion bevel (36), wherein via the insertion bevel (36) the front wall (20) can be brought into an elastically deformed state during an insertion of the filter element (10) into the receiving chamber (14), wherein in the elastically deformed state a longitudinal dimension (50) of the front wall is smaller than in an undeformed original state of the front wall (20), and wherein the insertion bevel (36) has a plate-shaped base part (56) which lies on a side wall (24) of the frame (16), at least one guide slope (52, 54) which extends diagonally away from the side wall (24), and a stiffening element (58) which is disposed between the plate-shaped base part (56) and the at least one guide slope (52, 54); and
an inherently rigid component (30) mounted on the frame (16) in an area of the front wall (20), wherein the fastening element (32) is formed integrally with the inherently rigid component (30) and wherein the inherently rigid component (30) has the insertion bevel (36).
