ABSTRACT:
A conveyor chain, which can be conveyed without being felled down in a curved conveying section even if the speed of the conveying line is increased is provided. A conveyor chain has a plurality of links (11) arranged in rows. Each of said links includes a top plate (12) having a flat top surface (13) and a hinge portion (14) provided on the top plate. The hinge portion is connected to the hinge portions in the adjacent link positioned on the backside by a pin. Engagement portions (14, 15, 21, 22) with the adjacent links positioned on the front and back sides in said top plate include flat surface portions (27˜30) connected to the flat top surface of the top plate, and the flat surface portions are extended to said adjacent link, positioned on the front or back side with respect to the central axis of the pin. Accordingly, when the link is passed through a curved conveying section, the engagement portions are overlapped with each other and do not produce a space between links, which changes the positions of conveying objects.
