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 fan pieces, consisting of a first fan piece and a second fan piece, which are biased in the opening direction by a spring, are pivotally attached to one of the fixed frame and the movable frame, and the first fan piece is The swinging end is brought into contact with the inner link, and the swinging end of the second fan piece is brought into contact with the outer link, and an actuation arm that is made to swing by an operating wire is pivotally attached to the frame, and this actuation arm is brought into contact with the inner link. When swinging from the link toward the outer link, it is possible to swing the first fan piece away from the inner link, while when the actuating arm swings from the outer link toward the inner link. 1. An external bicycle transmission, characterized in that the operating arm and both fan pieces are engaged with each other so that the second fan piece can be swung in a direction away from the outer link.
