ABSTRACT:
A wiper pivot is provided with a pivot arm, a pivot shaft having a spherical convex part, and a pivot holder having a spherical concave part. The pivot shaft is supported rotatably by the pivot holder through the spherical connection, and an opening of the pivot holder is closed with a waterproof member made from elastic material. In this wiper pivot, it is possible to prevent the pivot shaft from rattling and prevent the pivot holder from the penetration of water.
