1. A windshield wiper drive (1) for a motor vehicle, with a reverse-operating driving motor (3) for driving a wiper shaft (6) which is connected in a rotationally fixed manner to a wiper arm (18), and with a fastening plate (7) for fastening the windshield wiper drive (1) to a vehicle body, wherein a first end stop surface (22) for limiting rotational movement of the wiper shaft (6) in a first direction of rotation is provided on the fastening plate (7), wherein a second end stop surface (24) for limiting the rotational movement of the wiper shaft (6) in a second direction of rotation opposed to the first direction of rotation is provided on the fastening plate (7), wherein the first and the second end stop surfaces (22, 24) are arranged on two sides facing away from each other of a section (21) of the fastening plate (7), wherein one of the wiper arm and the wiper shaft has thereon a first counterstop surface (23) for interaction with the first end stop surface (22) and a second counterstop surface (25) for interaction with the second end stop surface (24), and wherein the section (21) projects into a guide slot (26) which is provided on the one of the wiper arm (18) and the wiper shaft (6), which extends in a circumferential direction and which has one of the counterstop surfaces (23, 25) at each of two ends spaced apart in the circumferential direction. 2. The windshield wiper drive as claimed in claim 1, characterized in that the wiper shaft (6) is arranged passing through a through opening (14) in the fastening plate (7). 3. The windshield wiper drive as claimed in claim 2, characterized in that the first and second end stop surfaces are formed by the inner contour of the through opening (14). 4. The windshield wiper drive as claimed in claim 2, characterized in that the first counterstop surface (23) and the second counterstop surface (25) are arranged on the wiper arm (18). 5. The windshield wiper drive as claimed in claim 1, characterized in that the first counterstop surface (23) and the second counterstop surface (25) are arranged on the wiper arm (18). 6. The windshield wiper drive as claimed in claim 1, characterized in that the fastening plate (7) has three fastening openings (8) which are spaced apart from one another in the circumferential direction. 7. The windshield wiper drive as claimed in claim 1, characterized in that the first counterstop surface (23) and the second counterstop surface (25) are arranged on a section (27) of the wiper arm (18), which section surrounds the wiper shaft (6), at least in sections. 8. The windshield wiper drive as claimed in claim 1, characterized in that the first counterstop surface (23) and the second counterstop surface (25) are arranged on a section (27) of the wiper arm (18), which section completely surrounds the wiper shaft (6). 9. A windshield wiper drive (1) for a motor vehicle, with a reverse-operating driving motor (3) for driving a wiper shaft (6) which is connected in a rotationally fixed manner to a wiper arm (18), and with a fastening plate (7) for fastening the windshield wiper drive (1) to a vehicle body, wherein a first end stop surface (22) for limiting the rotational movement of the wiper shaft (6) in a first direction of rotation is provided on the fastening plate (7), wherein a second end stop surface (24) for limiting the rotational movement of the wiper shaft (6) in a second direction of rotation opposed to the first direction of rotation is provided on the fastening plate (7), wherein the first and the second end stop surfaces (22, 24) are arranged on two sides facing away from each other of a radially inwardly directed radial section (21) of the fastening plate (7), wherein one of the wiper arm and the wiper shaft has thereon a first counterstop surface (23) for interaction with the first end stop surface (22) and a second counterstop surface (25) for interaction with the second end stop surface (24), and wherein the radial section (21) projects into a guide slot (26) which is provided on the one of the wiper arm (18) and the wiper shaft (6), which extends in a circumferential direction and which has one of the counterstop surfaces (23, 25) at each of two ends spaced apart in the circumferential direction.
