Abstract

L'invention concerne une structure de montage de réservoir dans laquelle un réservoir (10) est monté sur une plaque (40). Le réservoir (10) a une extrémité ouverte (11) fixée à la plaque (40) et a également une saillie (15) faisant saillie à partir de l'extrémité ouverte (11). La plaque (40) a une section d'extension (42) s'étendant le long de l'extrémité ouverte (11) et a également un trou (50) ouvert vers la section d'extension (42) et venant en prise avec la saillie (15). La périphérie interne du trou (50) comporte : un bord de fixation (51) en contact avec la saillie (15) et fixant le réservoir (10) à la plaque (40) ; et un bord latéral (53) courbé à partir du bord de fixation (51) et incliné selon un angle aigu par rapport au bord de fixation (51).
