Abstract

A toothed chain, which has a multiplicity of toothed links and cover links articulatedly connected to one another by cradle pieces. The cradle pieces are arranged in cradle piece openings of the toothed links and cover links. The cover links form guide links situated at the outside at both sides of a longitudinal direction and hold the toothed links between them. The cover links are formed with link yokes, which have a respective opening for the cradle pieces, and with an upper and lower link web which connect the link yokes. An opening is formed in the region between the upper and lower link webs, which has, in plan view, a substantially trapezoidal shape with sides of substantially equal lengths and an upper side and lower side of different lengths. The upper side is assigned to the upper link web and the lower side to the lower link web.
