Abstract
A bicycle derailleur comprises a stationary member to be fixed to a bicycle frame, a first shaft integral with and extending from the stationary member, a spring-biased swing member pivotally supported at one end by the first shaft, a second shaft 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 fixedly connected to and carried by the second shaft, and a restricting mechanism for restricting the second shaft from rotating about its own axis, so that a chain guide, 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.
