Abstract
A four member derailleur is disclosed having a control element which includes a plurality of engageable portions corresponding to the number of speed change stages mounted to one of the four members and a retainer for engaging with or disengaging from the engageable portions to keep a movable member of the four members in a proper position. The derailleur also includes means for moving the retainer in the direction of disengaging from each of the engageable portions so that when the movable member returns, through action of a return spring, the retainer may disengage from each of the engageable portions allowing the return movement of a chain guide.
