PURPOSE:To simplify an operation of the titled device, by so constituting that air is blown out only from a venting jet at the time when an ignition switch is turned OFF, in the titled device making use of a solar battery. CONSTITUTION:When an ignition switch 12 is made OFF, it becomes that a vacuum solenoid 10 operates an intake door 8 to an introduction side of the open air through an actuator 9 irrespective of ON or OFF of an intake switch 11. Then, a speed of a blower motor 13 of an intake unit 17 is adjusted by a fan switch 14 and power transfer of the blower motor 13 is done to a solar battery 1 side and the blower motor 13 is driven by the solar battery 1. On the one hand, even if the ignition switch 12 is made OFF a power source of a mode switch 27 is turned OFF and only a vent door 18 is turned into an open state. With this constitution, effective ventilation can be performed by simplifying an operation. |
