Abstract
Larger pre-tension is applied to each link such that residual compressive stress is larger at the portion of the link facing the inside of a chain than the outside. Assuming that for each of the links in a state that pre-tension is not applied, a predetermined pitch is P, a first inclination angle of a fixing portion of the front inserting portion with respect to a chain proceeding direction is α, and a second inclination angle of a fixing portion of the rear inserting portion with respect to a chain proceeding direction is β, when the pre-tension is applied to each of the links, the pitch changes into P+ΔP, the first inclination angle changes into α−Δα and the second inclination angle changes into β+Δβ where ΔP>0, Δα>0, and Δβ>0.
