1. A conveyor chain conveying a conveyance object by power transmitted via a sprocket meshed with the conveyor chain, comprising:
a first link plate extended along a conveying direction; a second link plate extended along the conveying direction and facing the first link plate in a direction perpendicular to the conveying direction; and a receiving member which is formed substantially rectangular, whose extended direction is in agreement with the conveying direction, and whose thickness direction is perpendicular to the facing direction of the first link plate and the second link plate, wherein a tongue piece, which is extended perpendicular to the second link plate and toward the first link plate, is provided at one of edges in a direction perpendicular to the extended direction of the second link plate, wherein the receiving member is formed integrally with and fixed to the second link plate via the tongue piece, and wherein the conveyance object is conveyed while being mounted on the receiving member, wherein a tapered surface, which reduces the thickness of the receiving member gradually along the extended direction, is formed at each of sides in the extended direction of a mounting surface of the receiving member, and a locus of sides of the mounting surface in the extended direction in a case in which the conveyor chain is meshed with and wound onto the sprocket is within an imaginary circle arranged coaxially to the sprocket, and the circle is specified so that a tangent of the circle is a straight locus of the mounting surface at a time of conveying the conveyance object. |
