ABSTRACT:
A derailleur in which a movable member is freely movable in its forward movement in a given range with respect to a base member without being subjected to action of a return spring, whereby when a control wire is pulled by a control lever, the stroke of the pull-operation, over the free rotation range, allows the movable member to move forward and the movable member, at the terminus of its forward movement, is movable forward freely within the given range such that it may be pulled by the tension of a bicycle chain engaging with a sprocket to complete a partially completed shifting operation.
