As a result, when the housings 100 and 200 abut each other, the gasket 300 will not be compressed excessively. And, in recent years, since the case needs to be reduced in size and thickness, the gasket 300 used here is also reduced in cross section and hardness so as not to load the housing 100 and 200 as much as possible. Is required.

Abstract

L'invention concerne un élément d'étanchéité pour lequel il n'est pas nécessaire de mettre en œuvre une rainure dans un logement et, en conséquence, il est possible de réduire la taille et l'épaisseur d'un carter ; un joint d'étanchéité pouvant être facilement manipulé ; et une performance d'étanchéité stable pouvant être maintenue. L'élément d'étanchéité est mis en œuvre entre un élément de logement et un autre élément de logement, et scelle un espace entre les deux éléments de logement. L'élément d'étanchéité comporte un élément de retenue composé d'un matériau de résine et ayant une section sensiblement en forme de H, et une paire d'éléments d'étanchéité en caoutchouc mis en œuvre d'une seule pièce dans les deux rainures de l'élément de retenue. Des parties de type lèvres faisant saillie depuis les deux rainures sont formées sur les deux éléments d'étanchéité en caoutchouc.
