Abstract

L'invention concerne un premier dispositif de butée (30) qui est équipé d'un boîtier (10) et d'un élément coulissant (31) prévu sur le boîtier (10) de manière à pouvoir coulisser. L'élément coulissant (31) est équipé : de deux parties de guidage (32) prévues sur le boîtier (10) de manière à pouvoir coulisser dans des directions parallèles, les parties de guidage (32) étant contraintes de se déplacer par rapport au boîtier (10) dans une direction croisant la direction de coulissement (S-1) ; d'une partie de liaison (33) reliant les parties de guidage (32) ; et d'une saillie faisant saillie à partir de la partie de liaison (33) vers le boîtier (10). Le boîtier (10) est équipé d'une surface interne de parois externes (11c), qui sont deux étapes où les parties de guidage (32) viennent en contact, et une partie convexe (16) sur laquelle la saillie (34) s'étend, la partie convexe (16) étant prévue entre les étapes. Dans le premier dispositif de butée (30), lorsque l'élément coulissant (31) coulisse et arrive au niveau du centre de la plage le long de laquelle l'élément coulissant (31) coulisse, la saillie (34) s'étend sur la partie convexe (16) et la partie de liaison (33) dévie du boîtier (10).
