BICYCLE DERAILLEUR

摘要

A bicycle derailleur has a base member, a movable member, a first link member and a second link member. The movable member is movable with respect to the base member between a retracted position and an extended position. The first link member includes a first connecting portion pivotally coupled to the movable member about a first pivot axis. The first link member is pivotally coupled to the base member about a second pivot axis. The second link member is pivotally coupled to the movable member about a third pivot axis. The second link member is pivotally coupled to the base member about a fourth pivot axis. The first connecting portion at least partially overlaps with the second link member as viewed in a direction parallel to the first pivot axis in a state in which the movable member is disposed at one of the retracted and extended positions.

1. A bicycle derailleur comprising:
a base member configured to be attached to a bicycle; a movable member configured to be movable with respect to the base member between a retracted position and an extended position at which the movable member is farther from the base member than the retracted position; a first link member including a first connecting portion pivotally coupled to the movable member about a first pivot axis, the first link member being pivotally coupled to the base member about a second pivot axis; and a second link member pivotally coupled to the movable member about a third pivot axis, the second link member being pivotally coupled to the base member about a fourth pivot axis, the first connecting portion at least partially overlapping with the second link member as viewed in a direction parallel to the first pivot axis in a state in which the movable member is disposed at one of the retracted position and the extended position.
