A chain (11) is formed by serially connecting links (13) each composed of a pair of link plates (12). The front end of one link (13) of adjacent links (13) is pivotally connected to the rear end of the other link (13). The chain (11) travels in one direction by being pulled in the longitudinal direction of the chain (11). Each of the link plates (12) has: a first end section (20) and a second end section (21), which extend in the longitudinal direction (X) of the chain (11); and an intermediate section (22) which is provided between the first end section (20) and the second end section (21) and which intersects the longitudinal direction (X). The thickness of the intermediate section (22) is greater than the thickness of both the first end section (20) and the second end section (21). |
