Abstract

L'invention concerne un mécanisme de rail à glissière et un siège de véhicule, avec lesquels une performance d'empêchement de délogement par rapport à un élément de ressort appliquant une pression sur un manche d'actionnement est améliorée. Un mécanisme à glissière (4) d'un siège de véhicule (S) comprend : un élément de verrou (30), qui limite un mouvement relatif d'un rail supérieur (20) par rapport à un rail inférieur (10) ; un élément de ressort (37), qui exerce une pression de telle sorte que le mouvement relatif du rail supérieur (20) est dans un état verrouillé ; et un manche d'actionnement (50), qui supporte la force appliquée de l'élément de ressort (37) et amène l'élément de verrou (30) à être positionné dans un état de libération de verrou. Une rainure d'accouplement (46), qui s'accouple à une partie de l'élément de ressort (37), est placée sur une partie de retenue (40) de l'élément de verrou (30). En outre, une partie de limitation saillante (47) est formée dans la partie de retenue (40) de l'élément de verrou (30) de telle sorte qu'une ouverture de la rainure d'accouplement (46) est rétrécie.
