Device for limiting the axial play

The plastics valve or shutter (2) is used in the ventilation system of a road vehicle. There is an attachment bracket for an actuator arm and two pivot disks (3) forming the ends of a swivel axis (1,101), associated with spring arms (4,104). The arms at the first side of the shutter are separated from the main body of the shutter by slits (6) and have outward-projecting ends (5). A cutout (108) at the second end accommodates the spring arm.
