Bicycle derailleur |
摘要 |
A bicycle derailleur basically includes a base member, a movable member, a chain guide, a friction element and a motor. 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 motor is operatively coupled to the movable member to move the movable member with respect to the base member. |

1. A bicycle derailleur comprising:
a base member configured to be mounted to a bicycle; a movable member movably coupled to the base member; a chain guide coupled to the movable member to rotate around a rotational axis with respect to the movable member; a rotational shall fixed to the chain guide and rotatably coupled to the movable member about the rotational axis; a friction element disposed on the movable member around the rotational shaft, the friction element having a friction applying member operatively arranged between the movable member and the rotational shaft to frictionally provide rotational resistance in a first rotational direction of the chain guide, the friction element including a friction adjusting member that contacts the friction applying member and is rotatably mounted on the movable member between at least a first position and a second position, the rotational resistance being larger with the friction adjusting member in the first position than in the second position; a one-way clutch disposed between the friction element and the rotational shaft; and a motor operatively coupled to the movable member to move the movable member with respect to the base member. |
