Abstract
A flap device for a heat exchanger of a vehicle has a support structure in which is formed a passage. A shutter is fitted to the passage, pivotable about an operationally horizontal axis (X-X) nearer to a first end of the shutter, between a rest position in which it closes the passage and a operating position in which it opens the passage, thereby allowing a flow of air to pass in a predetermined direction through the passage. In use, the shutter pivots from the rest position towards the operating position under the effect of a flow of air which strikes it in this direction, and returns by gravity towards the rest position when the air flow ceases. A stop projection formed on the first end of the shutter strikes an abutment surface on the structure when the shutter reaches the rest position.
