VEHICULAR VENTILATOR

PROBLEM TO BE SOLVED: To provide a vehicular ventilator capable of ventilating a cabin without providing any fan exclusive for ventilation to suck air in the cabin. SOLUTION: The vehicular ventilator comprises a fan 11 to blow air from an air-conditioning unit 10 in a cabin via an outlet, an exhaust passage forming member 31 which is branched from the air-conditioning unit 10 to form an exhaust passage 31a leading outside the cabin, a first opening/closing member 35 to open/close the exhaust passage 31a, a second opening/closing member 21 to open/close an air passage 17a leading from the air-conditioning unit 10 to the outlet, a control device 40 which opens the first opening/closing member 35 and closes the second opening/closing member 21 in the ventilation mode, operates the fan 11 to blow out air outside the cabin via the exhaust passage 31a, closes the first opening/closing member 35 in the air-conditioning mode to prohibit the blow-out of air outside the cabin, and flow passage forming members 21, 34, 35 to form a flow passage to suck the air in the cabin into the exhaust passage 31a from the outlet through induction of the flow of the air blown out via the exhaust passage 31a in the ventilation mode.
