PURPOSE: An air flap device for a vehicle is provided to prevent an engine from overheating due to the increasing temperature in an engine room because an air flap is opened and closed by an elastic material. CONSTITUTION: An air flap device for a vehicle(1) comprises an elastic member(10) and an opening and closing unit(100). The elastic member is connected to a resistor(20) arranged in a cooling fan of the vehicle. The elastic member is made of a shape-memory alloy which can change depending on the temperature. The opening and closing unit is installed in between a front grill and a radiator, and rotates depending on the contraction and relaxation of the elastic member. The opening and closing unit is connected to the elastic member by a connection member(30) in order to control the amount of outdoor air flowing into the radiator. |
