Abstract
A sprocket has a mounting part for mounting on a wheel and a corrugated section provided with teeth for engagement with a chain such that the sprocket has a reduces volume and weight and allows for appropriate engagement with the chain by having the position of the sprocket agree with the position of the chain. The mounting part has a first raised section raised toward a one plate surface side and a second raised section raised toward another plate surface side with respect to a longitudinally central plane extending through a center of the sprocket so as to divide the total volume and weight of the sprocket into substantially equal sections. A flat top part of the first raised section having a mounting hole is on a level with a bottommost end surface of the sprocket.
