ABSTRACT:
A multistage sprocket mechanism includes one or more sprockets each having two groups of teeth alternatively formed in the peripheral portion. The sprockets each includes two surfaces having a number of recesses and depressions alternatively formed in the peripheral portion and arranged close to the groups of the teeth. The recesses and the depressions each has a tapered bottom arranged corresponding to the respective groups of teeth for engaging with the driving chain and for reducing a friction between the driving chain and the sprockets.
