ABSTRACT:
A connecting mechanism for two members of a bicycle derailleur is provided with first and second bearings interposed between a supporting tubular member provided at a first member, such as a base member or movable member of the derailleur, and a shaft provided at a second member, such as a bracket member or chain change-over cage, each of the first and second bearings comprising a tubular portion inserted between the inner periphery of the supporting tubular member and the outer periphery of the shaft and a flange portion opposite to an end face of the supporting tubular member. At least one of the first and second bearings is provided at the flange portion thereof with an annular groove opening at one axial side of the flange portion. An annular elastically deformable sealing member is loosely fit into the groove and is elastically deformed to compensate for errors in the axial dimensions of the supporting tubular member, shaft, or bearings, thereby eliminating gaps produced at the surfaces of members slidably contacting with the bearings.
