The present invention relates to a wiper having a wiper arm (1) and a fastening element (3), the fastening element (3) being fastened on the wiper arm (1), and the fastening element (3) having a hub (4) which can be plugged onto a drive shaft (5). Precision alignment of the wiper relative to the drive shaft (5) is made possible in that the fastening element (3) is plugged into a cutout (2) in the wiper arm (1) in a form-fitting manner in one of at least two possible alignments. A wiper constructed in this way is, in addition, compact.

The wiper as claimed in claim 8, characterized in that the knurling (8, 9) of the fastening element, extends along an arc, and in that the portion of the edge of the fastening element (3) without a knurling extends substantially linearly from an end of the of the knurling (8, 9) of the fastening element. 10. The wiper as claimed in claim 9, characterized in that the edge of the fastening element (3) has a first portion without a knurling extending substantially linearly from one end of the knurling (8,9) of the fastening element and a second portion without a knurling extending substantially linearly from another end of the knurling (8,9) of the fastening element, the first portion and the second portion being non-parallel. 11. The wiper as claimed in claim 1, characterized in that the portion of the outer edge of the fastening element (3) without the knurling and the portion of the edge of the cutout (2) without a corresponding knurling are positioned in spaced apart relation. 12. The wiper as claimed in claim 1, characterized in that the cutout (2) has a substantially rectangular shape. 13. A method for aligning a wiper having a wiper arm (1) and a fastening element (3), with the fastening element (3) being fastened to the wiper arm (1), and with the fastening element (3) having a hub (4) which is plugged in a form-fitting manner onto a drive shaft (5) that merges into a screw, the method comprising inserting the fastening element (3) in a form-fitting manner, in one of at least two possible alignments, into a cutout (2) in the wiper arm (1), and fastening the wiper arm to the drive shaft with a nut threaded onto the screw, in that the fastening element (3) has, at an outer edge, a knurling (8, 9) which engages into a corresponding knurling (10, 11) on an edge of the cutout (2), the outer edge of the fastening element (3) having a portion with the knurling (8, 9) and another portion without a knurling, the portion with the knurling (8, 9) projecting from the portion without the knurling, the edge of the cutout (2) having a portion with the corresponding knurling (10, 11) and another portion without a corresponding knurling, the portion with the corresponding knurling (10, 11) being recessed into the portion without the corresponding knurling, and in that inserting the fastening element (3) includes inserting the fastening element (3) with the outer edge of the fastening element (3) positioned in facing relation with the edge of the cutout (2) and in at least one alignment of the fastening element (3) in the cutout (2) with a portion of the knurling (8, 9) on the fastening element (3) disengaged from the corresponding knurling (10, 11) on the cutout (2). 14.
