Abstract

Selon l'invention, un élément d'étanchéité de bord (60) fixé à une section d'extrémité sur un côté de section d'ouverture d'une section de coin (221C) ou d'une section ramifiée (221B) formée dans un élément de paroi (221) d'un corps principal de boîtier (22) comprend : une pluralité de premiers éléments (601) prenant en sandwich l'élément de paroi ; et un deuxième élément (602) reliant les éléments de la pluralité de premiers éléments. Les éléments de la pluralité de premiers éléments comportent des sections de face (601a) faisant chacune face à l'élément de paroi. Chaque section de face comporte une section en saillie déformable élastiquement (601b) avec une section creuse (601c) formée à l'intérieur de celle-ci.
