Claims

[Scope of utility model registration request]

A wiper pivot comprising a pivot arm that converts reciprocating motion of a link into a swinging motion, a pivot shaft that transmits the swinging motion converted by the pivot arm to a wiper arm, and a pivot holder that rotatably supports the pivot shaft, the wiper pivot comprising: The pivot shaft is formed with a small diameter shaft portion and a large diameter shaft portion, and the pivot holder is provided with a small diameter side bearing surface that supports the small diameter shaft portion and a large diameter side bearing surface that supports the large diameter shaft portion, and A wiper pivot characterized in that an oil sump groove is provided between the small diameter bearing surface and the large diameter bearing surface.
