An adjusting mechanism (13) is provided for a bicycle derailleur (10), which can adjust a position of a chain guide (26) in an axial direction. The derailleur (10) basically has a base member (20), a movable member with the chain guide (26) and a linkage assembly. The adjustment mechanism (13) is preferably operatively coupled between the movable member and the chain guide (26), or between the base member (20) and the frame (12). The adjusting mechanism (13) includes a first tubular portion (80), a second tubular portion (74), a biasing member (36) and an adjustment member. The second tubular portion (74) is arranged around the first tubular portion (80) to move axially relative to the first tubular portion (80) via the adjustment member. The biasing member (36) is arranged to apply an urging force on the tubular portions (74,80). One of the tubular portions (74,80) has a rigid non-compressible support projection (78) arranged to selectively contact the other tubular portion when the tubular portions (74,80) move relative to each other. <IMAGE> |
