Abstract

L'invention concerne un dérailleur pour une bicyclette permettant de changer sa vitesse en contrôlant un câble de Bowden Selon l'invention, il comprend un organe de base 1, des organes de liaison 2 et 3 pivotant sur l'organe 1, et un organe mobile 4 oscillant sur l'un des organes de liaison ; l'organe de liaison 3 forme une extension 31 qui a à son extrémité, un moyen de retenue du câble interne 11 du câble de Bowden; un bras basculant 9 pivote sur l'un des organes à l'exception du second organe de liaison; le bras 9 a à son extrémité un moyen de retenue de la gaine externe 12; la perpendiculaire à l'axe du second moyen de retenue à partir du point autour duquel le bras 9 oscille est plus petite que celle à l'axe du premier moyen de retenue à partir du point autour duquel oscille l'extension de l'organe 3; un ressort 10 est inséré entre le bras 9 et un autre organe mobile par rapport à celui sur lequel pivote le bras 9. L'invention s'applique aussi bien au dérailleur placé à l'avant qu'à l'arrière d'une bicyclette.
