PURPOSE:To make cylindrical compressed air generated on the discharging surface of front glass and a filmy cushion state around the surface function as the wiper by blowing compressed air against the discharging surface from a nozzle with a barrel and moving the nozzle. CONSTITUTION:The compressed air A from a compressor is introduced into a hermetically sealed vessel P, and the compressed air A is discharged to the discharging surface G of the front glass from the nozzles N with the barrels B (cavities) properly narrowed. The nozzles N are mounted by two or three along the front glass. When small holes a, b are bored to the bases of the barrels B attached into the nozzles and water and a detergent are each injected into the barrels B from these holes a, b, the water and detergent are mixed into the compressed air A discharged, changed into foggy form and blown against the discharging surface G. Since the compressed air A is blown cylindrically against the discharging surface G while the filmy cushion state K is generated around the cylindrical air, the cylindrical compressed air and the filmy cushion state can be made function as the wiper by properly moving the nozzles N. |
