This chain driving sprocket (11) comprises a rotation member (21) having a rotation axis, and multiple tooth bodies (24) arranged along the outer circumference of the rotation member (21) and supported by the rotation member (21). Each of the tooth bodies (24) has one or multiple teeth (24a) capable of engaging with a part of the chain. Between the rotation member (21) and the multiple tooth bodies (24), multiple elastic members (41, 42) are arranged configured so as to absorb impact applied to the tooth bodies (24) from the chain. The elastic members (41, 42) are of at least two types which have different shapes, form an angle relative to each other, and are arranged in different positions on the rotation member (21). |
