Abstract
A windshield wiper assembly which effects relatively smooth wiping motions as a pair of wiper blades are moved independently of each other such that the wiper blades do not interfere with each other. One wiper blade moving in a direction of approaching an overlapping area is stopped when that wiper blade has preceded the other wiper blade moving in a direction of moving away from the overlapping area by a first predetermined value or more. Meanwhile, the wiper blade moving in the direction of moving away from the overlapping area is stopped when that wiper blade has preceded the wiper blade moving in the direction of approaching the overlapping area by a second predetermined value or more exceeding the first predetermined value.
