Abstract
A derailleur for a bicycle is provided in which a support member is pivotally supported to a movable member of a linkage mechanism having a forcible movement mechanism. A chain guide is fixed to the support member at adjustable positions, so that the chain guide position can be adjusted by the forcible movement mechanism to change the moving direction of the chain guide. This enables the position of a guide pulley of the chain guide to be adjusted in position with respect to each sprocket of a multi-stage sprocket assembly.
