Abstract

L'invention concerne un dérailleur arrière pour une bicyclette pouvant faire passer une chaîne vers l'un des pignons constituant une roue libre en plusieurs stades attachée au moyeu arrière de la bicyclette. Selon l'invention, le dérailleur comprend un organe de fixation 1 fixé au cadre de la bicyclette, un mécanisme en pantographe A supporté oscillant sur l'organe 1 et comprenant un organe de support 2, deux organes de liaison 5 et un organe mobile 9, des cages de guidage 16 ayant des poulies 15, un moyen de sollicitation 17, et un support 20 entre l'organe de fixation et le mécanisme en pantographe pour maintenir ce dernier en une position particulière par rapport à l'organe de fixation afin que, quand l'organe mobile est déplacé axialement par rapport à la roue libre pour faire passer la chaîne à l'un des pignons, l'organe mobile puisse être déplacé radialement par rapport à la roue libre. L'invention s'applique notamment à l'industrie du cycle.
