Bicycle derailleur
First Claim
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 motor unit operatively arranged to move the movable member with respect to the base member;
a linkage including a first link pivotally connected to the base member and the movable member, the first link including a first linking member and a second linking member, the first linking member being pivotally connected to the movable member, the second linking member being pivotally connected to the base member, the second linking member being a separate member from the first linking member, the second linking member being attached to the first linking member; and
a saver mechanism including an output member movably operated by the motor unit, a drive link movably mounted on the first link between a drive transmitting position that connects a drive force of the motor to the first link and a non-drive transmitting position that disconnects the drive force of the motor from the first link, and a biasing element biasing the drive link into engagement with the output member to maintain the drive link in the drive transmitting position, the saver mechanism being supported between the first and second linking members.

Abstract
A bicycle derailleur includes a base member, a movable member, a motor unit, a linkage and a saver mechanism. The linkage includes a first link that includes a first linking member and a second linking member. The first linking member is pivotally connected to the movable member. The second linking member is pivotally connected to the base member, and is attached to the first linking member. The saver mechanism includes an output member movably operated by the motor unit, a drive link movably mounted on the first link between a drive transmitting position that connects a drive force of the motor to the first link and a non-drive transmitting position that disconnect the drive force of the motor from the first link, and a biasing element biasing the drive link into engagement with the output member to maintain the drive link in the drive transmitting position.
