PURPOSE:To prevent the operation of a wiper driving part in the state where washing water is not jetted-out, by allowing the wiping operation of the wiper driving part to start first when a raindrop sensor detects a portion of the washing water by the operation of a washer switch. CONSTITUTION:When a washer switch 2 is pressed, a washer driving part 9 operates, and washing water is sprayed in the wiping range on a front window by the right and left wipers. At the same time, the washing water is sprayed also in the detected range in the vicinity of a raindrop sensor 5 on the front window. Therefore, the rain drop sensor 5 operates to operate a wiper driving part 7. When washing water is not sprayed because of trouble, the raindrop sensor 5 dose not operate, and the wiper driving part 7 is not driven. Thus, the front window, wiper blades, etc. can be prevented from being damaged. |
