<p>PURPOSE: A suspending chain is provided to reduce costs for chain components by equipping a hanging chain without installing members such as a bush for reducing the number of the components. CONSTITUTION: A suspending chain(100) comprises an internal link plate(120), an external link plate(110), and a roller(140). The internal link plate is movably inserted into a connection pin(130). Both ends of the internal link plate are shaped into an arc. The internal and external link plates are alternately connected in a longitudinal direction by the connection pin. The internal and external plates are identically shaped. The roller is arranged between the internal link plates. The roller is movably and rotatably inserted into the outer circumference unit of the connection pin.</p> |
