<p>The present invention provides a chain for suspension having tensile strength increased compared with a one-column chain, having the number of parts decreased compared with a structure of each of a roller and a link plate having multiple columns, and made compact by having the width of the chain made narrow. The chain for suspension (100) according to the present invention comprises: first link plates (110) arranged at both outer sides in the widthwise direction of the chain from the roller (140); second link plates (120) arranged at both outer sides in the widthwise direction of the chain from the roller and arranged at inner sides or both inner sides and outer sides in the widthwise direction of the chain from the first link plate; and a connection pin (130) penetrating the hole (141) of the roller and the loose shrink-fit hole (111) of the first link plate to be able to rotate while shrink-fitted into the shrink-fit hole (121) of the second link plate. The first link plates and the second link plates are arranged at one side in the widthwise direction of the chain, with two or more for each roller respectively and the second link plates are at least arranged at an outermost side.</p> |
