PURPOSE:To cause the wiper of an automobile to be unnecessary and to improve the field of vision in the case of rainfall etc. by adhering sheets with repulsing property for water or with affinity for water on the windshield glass of the automobile. CONSTITUTION:Methyl methacrylate sheet 1 whose one side is coated with pressure sensitve adhesive 6 is adhered on a windshield 3. As the methyl methacrylate sheet 1 has repulsing property for water, rain-water becomes globular and is rolled and removed to the direction of arrow 5 by the wind-pressure from front side and the vibration of the car. Consequently, the field of vision is improved by removing the rain water from the field of vision. When the sheet with affinity for water is used, the rain water becomes uniformly thin film thereby preventing the decrease of visibility in the same way. |
