Provided is a shutter structure for a vehicular heat exchanger, the shutter structure being disposed in front of or behind a vehicular heat exchanger (200) with respect to a vehicle, the vehicular heat exchanger (200)having a plurality of stacked tubes (201a), through the inside of which a heat exchange medium flows, and adjusting the amount of air flowing through the vehicular heat exchanger (200). The shutter structure is provided with an opening and closing device (402, 502a) capable of switching between a first state in which at least a part of the gap between adjacent tubes (201a) is covered and a second state in which a smaller part of the gap between the tubes (201a) is covered than in the first state. The opening and closing device (402, 502a) is in the first state when the speed of air flow flowing from ahead of the vehicle toward the vehicular heat exchanger (200) is less than a predetermined value, and the opening and closing device (402, 502a) is changed from the first state to the second state by air flow when the speed of the air flow is more than the predetermined value. |
