PURPOSE: To maintain excellent visual perception for a long term even under wiper usage by using window pane having water-repellent film on outside and a wiper having wiper rubber formed of rubber material added with lubricant.
CONSTITUTION: Highly durable, water-repellent film is formed on surface of outside of a window pane for a vehicle. A rubber member of a wiper, sliding on surface of outside of glass having water-repellent film, is formed of rubber material added with lubricant. Accordingly, in operation a wiper in rain, lubricant exciting in the wiper rubber member oozes out to surface of rubber, so that abrasion between wiper rubber member and glass surface in rain is reduced. Abrasion rate of the water-repellent film is thus decreased, so that water- repellency is maintained for a long term and excellent visual perception is maintained for a long term.
