PURPOSE:To provide a ventilator which can be easily mounted on a car and maintain the interior thereof at a relatively low temperature when the car is parked in summer by driving an air supply means which exchanges inside and outside airs with each other, by the electric energy of a solar battery which is disposed on an air flow arranging panel. CONSTITUTION:A solar battery 12 is easily mounted on a car because it is housed in a transparent acryl resin case 13 and the case is put in the central recess 10a of an air flow adjusting plate 10. The contact point of a relay is closed since an ignition switch is opened during parking. In case of outdoor parking, the interior of a car is heated and once the temperature thereof exceeds a specified temperature, a bimetal switch 21 is connected to a contact point 2P and a manually operated switch is made to be turned into the closed condition so that the current across the solar battery 12 flows through a fan driving motor 18 to operate a ventilating fan 17. The air inside the car room 1 is forced to be sent out from an outlet opening 20 via a passage 16 while, at the same time, open air of a relatively low temperature is forced into the interior 1 of the car. |
