The utility model discloses an integrated into one piece bicycle chain wheel, including the fender chain dish of chain wheel body, chain wheel both sides with be equipped with the right crank of radial biography power claw, the quotation of chain wheel body distributes and has the via hole, and the fender chain dish and the right crank that is equipped with radial biography power claw of chain wheel body both sides be the single -casting, and wherein, divide in each via hole that chain wheel body quotation distributes and maybe connect the chain wheel both sides and keep off the foundry goods connecting portion that the chain coiled, right side crank is equipped with rather than being holistic, making it to support in centraxonial axle sleeve. This chain wheel when the fender chain dish of chain wheel body both sides and right crank and radial biography power claw become the single -casting the chain wheel body also rather than becoming whole, so of no use in the rivet or the screw of equipment between each parts of this chain wheel, has overcome and has presently prevented that the chain from coming off the chain wheel of function and having parts and process and the more loaded down with trivial details defect of assembly process. The utility model has the advantages of novel structure, facilitate the use, salient that overall structure reliably can not become flexible.
