Abstract

L'invention concerne une structure de fixation de volet d'un déflecteur de ventilateur (1) ayant une ouverture (7) formée au niveau d'une position hors d'un trou de ventilation (6) du ventilateur et ayant également un volet (8) pour fermer l'ouverture (7) sous l'effet de son propre poids et pour ouvrir l'ouverture (7) sous l'effet d'une rotation vers le haut par le vent relatif du véhicule. Un premier trou de fixation (10) et un deuxième trou de fixation (11) sont formés dans la partie supérieure du volet (8), à proximité l'un de l'autre dans la direction latérale. Une première pièce de fixation (12) et une deuxième pièce de fixation (13) sont installées sur le déflecteur de ventilateur (1). La première pièce de fixation (12) tient le volet (8) de telle manière qu'il entre dans le premier trou de fixation (10) et est plié en une forme généralement en L par rapport au côté du deuxième trou de fixation (11). La deuxième pièce de fixation (13) est mise en contact avec le deuxième trou de fixation (11) pour empêcher la première pièce de fixation (12) de se séparer du premier trou de fixation (10).
