Provided is a shutter device having a fail-safe function to prevent occurrence of overheating even when an actuator becomes inoperable. The shutter device includes a shutter valve (11) which opens and closes an air port, a lever (14a) having one end connected to a rotating shaft (16) of the shutter valve and the other end connected to an actuator (12), and biasing means which biases the shutter valve in an opening direction. Opening/closing of the shutter valve is controlled by the actuator rotating the lever when opening of the shutter valve is between the fully-open and predetermined opening, and the shutter valve is closed by wind pressure of travelling wind when the opening of the shutter valve is between the predetermined opening and the fully-closed.
