Abstract

Cette invention a pour objectif de réduire les disfonctionnements dus à la friction entre deux parties de couvercle, la friction entre le couvercle et le corps principal etc., dans une structure de raccord d'un corps de couvercle. Une partie d'extrémité de raccord (par exemple un deuxième raccord) est supportée de façon rotative sur une partie bras (par exemple une première partie bras) d'une première partie de couvercle. Entre l'autre partie d'extrémité de raccord (par exemple un deuxième raccord) et la partie bras (par exemple la deuxième partie bras) de la deuxième partie de couvercle sont situés un axe (par exemple un axe mobile) et un trou (par exemple un trou de liaison) dans lequel s'insère l'axe (par exemple un axe mobile). Dans le trou (par exemple un trou de liaison), par libération du verrouillage par action de pression sur la première partie de couvercle, le déplacement de l'axe (par exemple un axe mobile) est permis, et un espace (par exemple une partie de grand diamètre) interrompant le transfert de la force de rotation est formé.
