Patent ID: 8007383

Claim:
A bicycle rear derailleur comprising: a base member; a movable member that supports a chain guide including a pulley that rotates around a pulley axis, wherein the pulley has a pulley plane that bisects the pulley and is substantially perpendicular to the pulley axis; a first linking member coupled between the base member and the movable member so that the chain guide moves laterally relative to the base member between a first lateral position and a second lateral position; a first pivot shaft disposed at the first linking member to couple the first linking member to the base member; and a separate second pivot shaft disposed at the first linking member to couple the first linking member to the base member; wherein the first linking member pivots relative to the base member around a first pivot axis; wherein the pulley plane is disposed between the first pivot shaft and the second pivot shaft and is non-parallel to the first pivot axis; wherein the first pivot shaft and the second pivot shaft have respective first and second surfaces that face in directions towards each other, wherein the first and second surfaces do not contact each other when the first linking member is coupled to the base member.
