The wiper pivot unit for smoothly absorbing a load applied from the outside of a vehicle. The wiper pivot (1) has a pivot shaft (3), a pivot holder (4) and a toothed washer (5). The pivot shaft has a small-diameter section (31) and a large-diameter section (32). The toothed washer is fitted on the large-diameter section to constrict it with a predetermined force. The toothed washer slips off the large-diameter section when a load of a predetermined value or more acts upon the pivot shaft. When the toothed washer is shifted to the small-diameter section, the pivot shaft descends smoothly along the pivot holder.
