Abstract: A derailleur for a bicycle, which is operated by a control wire. Between a base member and a movable member a stiff swingable member is positioned and is pivoted to both the members through first and second shafts. A regulator controls the rotation of the movable member with respect to the swingable member so that the movable member is made movable by the swingable member with respect to the base member while the shafts are kept in parallel to each other. The movable member is divided to fixedly sandwich the control wire between the divided segments, thereby ensuring fixing of the wire.
