Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an air suction device at the front of a vehicle having shutters closed when a heat exchanger is overcooled. SOLUTION: This air suction device 22 at the front 10b of the vehicle comprises the shutters 32, 33 installed at air suction holes 23, 24 and opened by air pressure, the heat exchanger 25, a fan 26 disposed at the rear of the heat exchanger 25, and a control part 36 controlling the fan 26. When the heat exchanger 25 is detected to be overcooled, the control part 36 reversely rotates the fan 26 to controllably close the shutters 32, 33 against a traveling air pressure. The control part 36 variably controls the reverse rotational speed of the fan 26 according to the speed of the vehicle 10. COPYRIGHT: (C)2008,JPO&INPIT
