There is provided a conveyor chain whose durability and maintenance performance are improved by suppressing uneven wear of inner link plates otherwise caused by contact with rollers inclined due to carriers attached to link plates by utilizing flanges of the rollers fitted around bushings fixed to the inner link plates. In the conveyor chain of a bucket conveyor, the washer that prevents the inner link plate from contacting the roller is disposed between the inner link plate and the roller in an axial direction and is secured to the inner link plate. A plate outer peripheral edge of the inner link plate and a washer outer peripheral edge of the washer are located outside of a roller outer circumferential surface in the radial direction centering on a center axial line of the bushings. A washer outer peripheral edge is formed into such a shape that keeps away the roller from contacting the inner link plate by causing the flange contact the first washer at the position radially outside of the roller outer circumferential surface when the roller inclines.
