  • Patent number: 6347427
    Abstract: A wiper device for a vehicle disclosed is provided with a wiper motor, a wiper pivot connected to the wiper motor, and a pivot holder having a base portion attached to the vehicle body and a bearing hole pivotally supporting the wiper pivot in a rotatable manner. Here, the wiper pivot can rotate around the pivot axis thereof by using a drive force from the wiper motor and has a cutout portion, and the wiper pivot extends so as to project toward an outer side of the vehicle body. In such a structure, it is further structured such that a C ring engaged with the cutout portion of the wiper pivot is released from the cutout portion when a load equal to or more than a predetermined value acts on the wiper pivot. In this case, as a result, the wiper pivot is moved to an inner side of the vehicle body.

  • Patent number: 6216309
    Abstract: A wiper device for a vehicle disclosed is provided with a wiper motor, a wiper pivot connected to the wiper motor, and a wiper frame in which the wiper pivot is arranged. In this case, the wiper pivot can rotate around the pivot axis thereof by using a drive force from the wiper motor, and the wiper pivot extends so as to project toward an outer side of the vehicle body. Further, the wiper frame has a bracket portion fixing the wiper frame to the vehicle body. Then, in the structure mentioned above, it is constructed in such a manner that the bracket portion of the wiper frame is released from the vehicle body so as to move the wiper pivot to an inner side of the vehicle body when a load equal to or more than a predetermined value acts on the wiper pivot.
