たことを特徴と、す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 operation of an operating wire, and a chain guide member attached to the movable frame can be shifted.
A pair of hanging pieces is pivotally attached to either the inner link or the outer link, and these are urged in the opening direction by a spring, so that the swinging end of each voice piece comes into contact with the link. Further, an actuation arm that is pivoted by an operating wire is pivotally attached to the link, and when the actuation arm swings in one direction, one of the hanging pieces can be swung in a direction away from the link. The actuating arm and both hanging pieces are engaged with each other so that when swinging in one direction and the other, the other hanging piece can be swung in a direction away from the link. , exterior derailleur for bicycles.
