Claims

[Scope of utility model registration request]

A chain that hangs between the multi-stage front gear and the rear gear of a bicycle, and when changing the chain with the front derailleur, this eliminates the problem of the chain part that bites into the front gear shifting to the front derailleur side. A device that extends near the rear of the front gear in a chain stay of a bicycle, axially outward of the front gear and above the movement locus of a driven chain portion of the chain, and that engages the front gear. A device for eliminating chain jamming in a bicycle, characterized in that a blocking body 5 is provided to buffer the chain moving toward the front derailleur side and to separate the chain from jamming with the front gear.
