PURPOSE:To prevent a windshield from clouding without fail as well as to secure its sightability in time of driving, by making a cloud eliminating device so as to be kept in an operating state unless an engine is stopped at a time when a cloud on the windshield is once detected during engine operation. CONSTITUTION:A cloud detecting device (humidity sensor) 1, emitting an electric signal corresponding to a moisture quantity contained in air inside a car room, is et up in the vicinity of an object windowplane (rear glass) surface. In addition, there is provided with a driving state detecting device 2 which takes out the electric signal as interlocked when an engine is made on or off by making a key switch of a car, and the output signal is inputted into a control device 3 together with a cloud detecting signal. And, while the electric signal showing that the engine is in operation is being inputted, a refrigerating cycle device is operated when the electric signal, showing a cloud generating state, is once inputted from the cloud detecting device 1, whereby a cloud eliminator 4 eliminating the cloud is controlled so as to be operated. |
