ばねを設けたことを特徴とする自転車用ディレーラ−０A four-speed link mechanism is constructed by a movable member having a base member, two link members, and a chain guide, and the movable member is reciprocated in one direction in the axial direction of the multi-stage sprocket with respect to the base member by pulling the operation wire. The bicycle derailleur is configured such that the arm is pivoted to the four-speed link mechanism in a range narrower than the sprocket spacing of the multi-stage sprocket. The return spring is supported freely and interposed between the arm and the four-speed link mechanism, and the movable member is attached to the four-speed link mechanism on the small diameter sprocket side of the multi-stage sprocket. A bicycle derailleur-0 characterized by being provided with a control spring that exerts force on the bicycle.
