The invention relates to a windshield wiper device, particularly for a motor vehicle, comprising at least one wiper shaft (10). Prior art windshield wiper devices having predetermined breaking points exist in order to meet the high demands of pedestrian impact protection. However, the risk of these predetermined breaking points rupturing during the operation of the wiper exists in this type of windshield wiper device. In addition it cannot be guaranteed that the predetermined breaking point ruptures in the event of a pedestrian impact. Therefore, in the inventive windshield wiper device, the at least one wiper shaft (10) can be displaced under the action of a force.
