Abstract: Shutter device for a front grille of a vehicle that according to one embodiment includes a frame, a driving flap pivotally coupled to the frame and suitable for pivoting between an airflow blocking position and an opening position. The driving flap is coupled to a rotary actuator by a rotary shaft for moving the driving flap. The shaft includes a first stop configured for being supported on a first final stop of the frame when the driving flap is arranged in the blocking position. The shaft also includes a second stop arranged on the shaft, the second stop being axially and angularly displaced with respect to the first stop, and is also configured for being supported on a second final stop of the frame when the driving flap is arranged in the blocking position.
