The invention relates to a gear housing (1) comprising a gear, particularly comprising a gear of a wiper device for motor vehicles, having a housing base body (4), having a housing cover (3) affixed at a distance to the housing base body (4) by means of a plurality of retaining clips (6) made of spring steel in circumferential direction, and having an annular seal (20) disposed between the housing base body (4) and the housing cover (3) and pressed against a support region (24) of the housing base body. The invention provides that the radial extension (y) of the support region is smaller than the radial extension (x, x′) of the annular seal.

1. A gear housing with a gear unit with a housing base body (4), with a housing cover (3) secured to the housing base body (4) by means of a plurality of retaining clips (6) made of spring steel which are spaced apart in the circumferential direction, and with a ring seal (20) which is arranged betw
1. A gear housing with a gear unit with a housing base body (4), with a housing cover (3) secured to the housing base body (4) by means of a plurality of retaining clips (6) made of spring steel which are spaced apart in the circumferential direction, and with a ring seal (20) which is arranged between the housing base body (4) and the housing cover (3) and which is pressed against a bearing region (24) of the housing base body (4), characterized in that the radial extension (y) of the bearing region (24) is smaller than the radial extension (x, x′) of the ring seal (20), and characterized in that the ring seal (20) is designed as an extruded profile, wherein the ring seal (20) defines a non-mounted width and a mounted width, and wherein the mounted width is greater than the non-mounted width as a result of the bearing region (24) pressing against the ring seal (20) in a mounted state causing the radial extension (x, x′) of the ring seal (20) to broaden. 2. The gear housing as claimed in claim 1, characterized in that the bearing region (24) is formed by a planar circumferential edge face (22) of the housing base body (4). 3. The gear housing as claimed in claim 2, characterized in that a lateral face (25) of the ring seal is directed toward the housing base body (4) and is planar in an uncompressed state. 4. The gear housing as claimed in claim 3, characterized in that, in a compressed state, the ring seal (20) overlaps the bearing region (24) in the mounting direction (7). 5. The gear housing as claimed in claim 4, characterized in that the ring seal (20) is arranged in a receiving groove (21) of the housing cover (3) in an uncompressed state. 6. The gear housing as claimed in claim 5, characterized in that at least one stop (19) is provided on the housing base body (4) for supporting the housing cover (3). 7. The gear housing as claimed in claim 6, characterized in that each retaining clip (6) is assigned to one of the stops (19). 8. The gear housing as claimed in claim 7, characterized in that the retaining clips (6) are positioned to exert a compressive force on an upper side (12) of the housing cover in the direction of the housing base body (4). 9. The gear housing as claimed in claim 8, characterized in that the retaining clips (6) are retained by means of a receiving opening (9) against latching lugs (15) which extend in the radial direction from the housing base body (4) and which are provided with a run-on ramp (16) directed in the mounting direction (7). 10. The gear housing as claimed in claim 2, characterized in that the ring seal (20) is arranged in a receiving groove (21) of the housing cover (3), characterized in that the receiving groove (21) defines a first width at a base of the receiving groove (21) and a second width at an opening of the receiving groove (21) and proximate the planar circumferential edge face (22), wherein the second width is greater than the first width such that the ring seal (20) is permitted to widen in response to contact with the planar circumferential edge face (22). 11. The gear housing as claimed in claim 1, characterized in that a lateral face (25) of the ring seal is directed toward the housing base body (4) and is planar in an uncompressed state. 12. The gear housing as claimed in claim 1, characterized in that, in the compressed state, the ring seal (20) overlaps the bearing region (24) in the mounting direction (7). 13. The gear housing as claimed in claim 1, characterized in that the ring seal (20) is arranged in a receiving groove (21) of the housing cover (3) in an uncompressed state. 14. The gear housing as claimed in claim 1, characterized in that at least one stop (19) is provided on the housing base body (4) for supporting the housing cover (3). 15. The gear housing as claimed in claim 14, characterized in that each retaining clip (6) is assigned to one of the stops (19). 16. The gear housing as claimed in claim 1, characterized in that the retaining clips (6) are positioned to exert a compressive force on an upper side (12) of the housing cover in the direction of the housing base body (4). 17. The gear housing as claimed in claim 1, characterized in that the retaining clips (6) are retained by means of a receiving opening (9) against latching lugs (15) which extend in the radial direction from the housing base body (4) and which are provided with a run-on ramp (16) directed in the mounting direction (7). 18. The gear housing as claimed in claim 1, characterized in that the ring seal (20) is arranged in a receiving groove (21) of the housing cover (3), characterized in that the receiving groove (21) defines a first width at a base of the receiving groove (21) and a second width at an opening of the receiving groove (21) and proximate the bearing region (24), wherein the second width is greater than the first width such that the ring seal (20) is permitted to widen adjacent the bearing region (24).
