Abstract: The purpose of the present invention is to provide a conveyor chain conveying a conveyance object such as a bucket while the conveyance object is mounted thereon, wherein the conveyance object can be conveyed to a predetermined position while both the conveyance object and the receiving member are not damaged by “biting” or “hooking” at upstream or downstream end in a conveying direction. An upstream tapered surface and a downstream tapered surface, which reduce the thickness of the receiving member gradually along the extended direction, are formed respectively at sides in the extended direction of a mounting surface of the receiving member. A locus of the mounting surface in a case in which the conveyor chain is meshed with and wound onto a sprocket is within a circle which is coaxial to the sprocket and whose tangent is a straight locus of the mounting surface in a case of conveying a bucket (conveyance object).
