PROBLEM TO BE SOLVED: To prevent waterdrops from attaching to a curve mirror or a road sign and prevent their freezing. SOLUTION: The waterdrop adhesion prevention device is structured by combining a vibrator 2 to vibrate a target 10 of vibration, a humidity sensor 6 to detect the humidity of outside air adjacent to the target 10, a control section 5 bringing the vibrator 2 into operation at a time when the result of detection of the humidity sensor indicates 100% humidity. An anti-icer is structured by combining a vibrator 2 to vibrate the target 10, a temperature sensor 7 to detect the surface temperature of the target 10, and a control section 5 to control the vibrator 2 so as to operate at a time when the result of detection of the temperature sensor is 0 deg.C or lower. |
