ディレーラ。A movable member movable in the axial direction of the multi-stage sprocket device is supported on the base member via a swing link-type feeding means, and the movable member guides the drive chain 7 to one sprocket of the multi-stage sprocket device. A derailleur that supports a guide mechanism that moves and a coiled return spring interposed between the base member and the feeding means,
The return spring is disposed at a position offset from the support position of the sending means on the base member, and a spring bearing having a higher hardness than the base member is provided on one of the base member and the link member. A bicycle derailleur characterized in that a contact portion of the bridge with the return spring has a curved surface with a small radius of curvature.
