Abstract

L'invention concerne un dispositif de poulie (1) pour galet tendeur ou enrouleur pour un élément de transmission comprenant un roulement (3) et une poulie (2). La poulie (2) est pourvue de deux éléments de poulie (21, 22) ayant une forme en C en section de coupe axiale. Au moins un des éléments de poulie (21, 22) comprend une ouverture traversante (40, 41) axialement, l'autre élément de poulie (22, 21) comprenant une portion en protrusion (44, 45) axiale logée dans ladite ouverture (40, 41), une collerette (46, 47) étant formée par déformation de la portion en protrusion (44, 45) afin d'assurer une retenue axiale avec ladite ouverture (40, 41). L'au moins une ouverture traversante (40, 41) est pourvue à sa périphérie d'au moins une zone en creux (40a, 40b, 41a, 41b) formée en retrait essentiellement radialement par rapport à ladite protrusion (44, 45) qui traverse ladite ouverture (40, 41).
