A bicycle derailleur comprises a base member (100), a movable member (104) for supporting a chain guide, a first link member (120) pivotably coupled to the base member (100) and to the movable member (104) through respective first and second link pins (128,138), a second link member (124) pivotably coupled to the base member (100) and to the movable member (104) through respective third and fourth link pins (146,154), and a motor having a drive shaft that defines a drive shaft vector V. The first through fourth link pins (128,138,146,154) define edges of a phantom space, wherein straight continuous phantom lines connecting ends of the first through fourth link pins (128,138,146,154) in a non-crossing manner define remaining edges of the phantom space. At least a part of the primary motor housing (214) is disposed in the phantom space, and the drive shaft vector V points away from a plane P2 containing the second and fourth link pins (138,154). <IMAGE> |
