ABSTRACT:
A rear derailleur for a bicycle, which is provided with a holder connected between a fitting member fixed to the bicycle frame and a pantograph mechanism supported to the fitting member through a transverse stud. The holder offsets the position of a movable member with respect to the fitting member, or in other words, the position of the movable member with respect to each sprocket at the freewheel, so that when the movable member is moved axially of the freewheel to switch a driving chain to a selected sprocket, the movable member is moved radially of the freewheel. Therefore the movable member, when moved axially of the freewheel for switching a driving chain to a selected one of the sprockets, is moved radially of the freewheel.
