Claims

[Scope of utility model registration request]

A base member 1, an inner link member 2 and an outer link member 3 pivotally supported on the base member 1 via a pair of link pins 6, 7, and a pair of link pins 8, 9 attached to these link members 2, 3. A linkage mechanism A consisting of four members is provided, with a movable member 4 having a chain guide 5 pivotally supported therebetween, and each of the connecting pins 6, 7,
8 and 9 are respectively inclined with respect to a plane perpendicular to the axis of the multi-stage sprocket device when mounted on the bicycle, and when the link mechanism A is deformed, the chain guide 5 is moved in the radial direction of the multi-stage sprocket device. In this bicycle derailleur, the inner link member 2 is connected to the base member 1, and the upper edge of the inner link member 2 connects the outer link member 3 to the upper edge of the outer link member 3. With respect to the extension line XX extending perpendicularly to the center line of the connecting pin 7, the lower end of the inner link member 2 is displaced toward the axis of the multi-stage sprocket device, and the lower edge of the inner link member 2 is aligned with the outer link member 3. A bicycle characterized in that the bicycle is pivoted so as to be displaced toward the axis of the multi-stage sprocket device by an extension line X ₂ _- dayrailer.
