Claim:
An adjusting mechanism for adjusting a position of a chain guide of a bicycle derailleur in an axial direction, said adjusting mechanism comprising: an axle having a first end and a second end with a longitudinal axis extending between said first and second ends; a first tubular portion pivotally coupled on said axle to rotate about said longitudinal axis; a housing having an attachment portion adapted to be coupled to a linkage assembly of the bicycle derailleur and a second tubular portion arranged around said first tubular portion, said second tubular portion being non-rotatably arranged relative to said first tubular portion; a biasing member arranged to apply an urging force on said first and second tubular portions about said axle; and an adjustment member operatively coupled between said housing and said first tubular portion to move said housing relative to said first tubular portion in an axial direction on said axle, one of said first and second tubular portions having a rigid support projection arranged to selectively contact the other of said first and second tubular portions when said first and second tubular portions move relative to each other in a direction generally perpendicular to the longitudinal axis of the axle from non-contacting positions to contacting positions, said support projection being non-compressible.
