    Abstract: A rear derailleur is basically provided with a base member, a movable member, a chain guide, a friction element, a one-way clutch and an electric actuator. The base member is configured to be mounted to a bicycle. The movable member is movably coupled to the base member. The chain guide is coupled to the movable member to rotate around a rotational axis with respect to the movable member. The friction element is operatively arranged between the movable member and the chain guide to frictionally provide rotational resistance in a first rotational direction of the chain guide. The one-way clutch is operatively disposed between movable member and the chain guide to engage the friction element as the chain guide rotates in the first rotational direction. The electric actuator is operatively coupled to the one-way clutch to control the one-way clutch between a clutch-on mode and a clutch-off mode.

    Abstract translation: 后拨链器基本上设置有基部构件,可动构件,链条引导件,摩擦元件,单向离合器和电动致动器。 基座构件被安装到自行车上。 可移动构件可移动地联接到基座构件。 链条引导件联​​接到可动构件,以相对于可动构件绕旋转轴线旋转。 所述摩擦元件可操作地设置在所述可动构件和所述链条导向件之间,以在所述链条引导件的第一旋转方向上摩擦地提供旋转阻力。 单向离合器可操作地设置在可动构件和链条引导件之间,以在链条引导件沿第一旋转方向旋转时与摩擦元件接合。 电致动器可操作地联接到单向离合器以在离合器接通模式和离合器关闭模式之间控制单向离合器。
