The invention provides a load-carrying conveyor chain that can be bent backward, realizing spatial three-dimensional conveyance, and can be hooked deeply by sprocket teeth, thus rarely causing jump of the teeth. The chain is constructed by endlessly connecting link bodies each having a head composed of a hollow cylindrical portion defined by walls having elongated pin holes extending circumferentially of the cylindrical portion, and a pair of legs respectively having pin holes by inserting a rotatable bearing body having a through pin hole into the cylindrical portion and by inserting connecting pins into the pin holes of the legs, the elongated pin holes of the head and the through pin hole of the bearing body while disposing the head of one link between the pair of legs of the contiguous other link. One end of the bearing body is extended to project out of the cylindrical portion and the bearing body has a flange at the projecting end.
