Abstract
A bicycle rear derailleur equipped with a base component, a link mechanism, a movable component, outer plate, inner plate, guide pulley, and tension pulley. The base component is mounted on the frame and one end of the link mechanism is mounted on the base component. The movable component is mounted on the other end of the link mechanism, and can be relatively displaced from the base component. The outer plate is mounted on the movable component so as to undulate like a see-saw. The guide pulley is mounted between the plates, so as to freely rotate and move in the axial direction. The tension pulley can be engaged with the chain, the engagement center of which is set at a position closer to the outer plate than to the engagement center of the guide pulley, and is mounted between the plates, so as to freely rotate.
