Description

ABSTRACT:
A wiper device having a simple structure by which nearly the entire rectangular windshield surface of a vehicle can be wiped. In the wiper device, an arm comprises a drive link adapted to reciprocatively swing according to a drive operation of a wiper drive unit, a connecting link swingably and pivotally supported at an extreme end portion of the drive link, an operating link having a base end portion integrally fixed to the connecting link, a guide link that has a base end portion, which is swingably and pivotally supported on the vehicle body, and an extreme end portion, which is swingably and pivotally supported on the other end portion of the connecting link, and that is operative to guide the operating link in such a manner that the extreme end portion of the operating link reciprocatively moves in an approximately straight line with a reciprocative movement of the drive link, a supporting link swingably and pivotally supported at the extreme end portion of the operating link, and a holding link that has an extreme end portion, which is swingably and pivotally supported on the supporting link, and a base end portion, which is swingably and pivotally supported on the guide link, and that is operative to hold the supporting link in such a manner that the angle (.theta.) between the supporting link and the movement locus (A) of the extreme end portion of the operating link is maintained at a nearly constant value.
