る自転車用外装変速機。In an external bicycle transmission, the pantograph mechanism consisting of a fixed frame, an inner link, an outer link, and a movable frame is deformed by operating an operating wire, and a chain guide member attached to the movable frame can be shifted.
A pair of side pieces are pivotally attached to the fixed frame, biased by springs in the opening direction, and the swinging end of each side piece is brought into contact with a stopper provided on the fixed frame, Of a pair of relatively movable operating ends of the operating wire, one operating end is fixed to any member of an inner link, an outer link, a movable frame, or a connecting pin that connects these, while the other operating end is It is fixed to an actuating arm that is swingably pivoted to a fixed frame, and furthermore, when the actuating arm swings in one direction, one side piece can swing in a direction away from the stopper that comes into contact with it. The actuating arm and both hanging pieces are engaged with each other so that when the other side piece swings in the other direction, the other side piece can swing away from the stopper that abuts the other side piece. An external bicycle transmission characterized by:
