<p>A bicycle derailleur comprises a stationary member (1/101) to be fixed to a bicycle frame, a first shaft (10/110) integral with and extending from the stationary member, a spring-biased swing member (12/112) pivotally supported at one end by the first shaft, a second shaft (11/111) extending through the swing member at a position spaced apart from the first shaft in parallel relation with respect to the first shaft and in relatively rotatable relation with respect to the swing member, a movable member (4/104) fixedly connected to and carried by the second shaft (11/111), and a restricting mechanism for restricting the second shaft from rotating about its own axis, so that a chain guide (7/107), which is operatively supported by the movable member, can move laterally with maintaining a certain constant positional relation with respect to a multi-speed driving gears of a bicycle.</p> |
