ABSTRACT:
A vehicle wiper for use with a vehicle windshield includes a first lever having opposing end portions, a plurality of second levers supporting a rubber wiper blade, the first lever having the second levers pivotably connected to the end portions of the first lever while being pivotably held to a wiper arm at an intermediate portion of the first lever. The first lever includes a first mounting portion having spaced, opposing sides and a pair of walls defined at the opposing sides so as to permit the first lever to be mounted to the wiper arm and a pair of second mounting portions, each having a pair of walls spaced apart from each other. A fin portion is defined between the first mounting portion and the second mounting portion and extends from the first and second mounting portions. The fin portion has a rear edge portion formed at a top portion thereof, thereby preventing the wiper blade from being lifted from the windshield so as to wipe against the windshield when the vehicle travels at high speed. Twisted portions integrally combine the fin portion with the first mounting portion as well as the second mounting portion, in such a manner that the fin portion is joined smoothly and continuously and is integral with a front wall of the first mounting portion and a front wall of the second mounting portion.
