Wiper device.

摘要

A wiper device (1) comprises a wiper arm (2) a pivot shaft (4), a lever (8), a connecting pin (5) and an eccentric bearing mechanism (9) provided with an eccentric bearing (9a) to the lever (8) and for rotating the bearing (9a) around the axis (50) of said connecting pin (5) and narrowing the wiping area on the wiped surface (52) when the torque applied on said bearing (9a) is larger than predetermined value. According to the device, it is possible to reduce the parts of the mechanism for varying the wiping area in number, and possible to make the wiping device compact.
