Une projection (10) est en saillie radialement vers l'intérieur depuis une paroi périphérique intérieure (111w) d'une section cylindrique extérieure (111). Une projection (30) est agencée dans la direction circonférentielle de la section cylindrique extérieure (111) à une position différente de la position à laquelle la projection (10) est agencée. Une section en pente (81) s'étend vers le bas depuis une extrémité supérieure (79) vers une extrémité inférieure (78), au niveau d'une pente le long de la direction circonférentielle d'une section cylindrique intérieure (193). Une section horizontale (82) s'étend dans la direction horizontale à partir de l'extrémité inférieure (78) de la section en pente (81) le long de la direction circonférentielle de la section cylindrique intérieure (193). Une section en pente (84) s'étend depuis une extrémité supérieure (76) vers une extrémité inférieure (77) le long de la direction circonférentielle de la section cylindrique intérieure (193), au niveau d'une pente dans la direction circonférentielle de la section cylindrique intérieure (193).
