Abstract

L'invention concerne un dérailleur de bicyclette. Ledit dérailleur, qui est monté à l'intérieur du cadre de la bicyclette, est aligné avec les pignons arrière. Le dispositif de renvoi supporte deux petits pignons sur lesquels passe la partie détendue de la chaîne. Ce dispositif est supporte par une tige de manoeuvre qui est engagée dans un dispositif de positionnement destiné à assurer un transfert positif de la chaîne d'un pignon à l'autre et l'alignement du dispositif de renvoi et de la chaîne avec les pignons individuels. Ce dispositif de positionnement comporte des plaques superposées dans lesquelles sont ménagées des fentes configurées de façon à guider la tige pour transférer efficacement la chaîne et l'aligner avec les pignons individuels. Application à un changement de vitesses par dérailleur pour bicyclette à plusieurs vitesses.
