Claim:
A bicycle derailleur comprising: a first base member structured to be detachably mounted to a bicycle frame, wherein the first base member has a first abutment; a second base member structured to be mounted to the first base member, wherein the second base member has a second abutment that faces the first abutment of the first base member; wherein the first base member and the second base member define a housing space therebetween; a drive mechanism having a drive mechanism housing at least partially disposed in the housing space; wherein the drive mechanism housing is separate from the first and second base members, a link mechanism having a link member that moves in response to movement of the drive mechanism; wherein the drive mechanism housing has a link shaft extending therefrom to which the link member is mounted for pivoting around a rotational axis of the link shaft; a chain guide coupled to the link mechanism for moving a chain among a plurality of sprockets; and a misalignment inhibiting structure disposed between the first base member and the second base member to inhibit misalignment of the drive mechanism housing by preventing forces applied to the first and second base members from being transmitted to the drive mechanism housing.
