PURPOSE:To eliminate the complications of the opening and shutting of a window with manual operation for ventilation by providing an air-pollution sensor sensing smoke or actor inside a car and a window opening and shutting means opening the window when the sensor detects the smorke or the odor and shutting the window when the smoke or the odor is not detected by the sensor. CONSTITUTION:A mode change-over switch 23 is turned ON, and when a detection signal of an indoor smoke sensor 24 is inputted to a micro-computer 1, a detection level of the indoor smoke sensor 24 is compared with reference value set in advance. After that, when the detection level is higher than the reference value, a detection signal from an opening amount detection sensor 26 is compared with the reference value set in advance to decide a current opening amount of the window. Then, when the current opening amount of the window is not wider than the reference value, a window driving device 31 is driven to open the window. |
