PROBLEM TO BE SOLVED: To provide a chain which can suppress the deformation of a link plate.SOLUTION: Each link plate 12 of a link 13 constituted of opposing two link plates 12 is connected to each link plate 12 of the other links 13 which adjoin in a serial direction X so as to be turnable at each end, each link plate is pulled from one side of the serial direction X, and a chain 11 moves. The link plate 12 extends so that one end 20 and the other end 21 thereof extend in the serial direction X being the moving direction of the chain 11, and an intermediate part 22 being a region other than the one end 20 and the other end 21 extends so as to intersect with the serial direction X. Then, the thickness of the intermediate part 22 is thicker than thicknesses of the one end 20 and the other end 21. |
