链条
摘要：
链条(11)通过将多个由一对链节板(12)形成的链节(13)串联连接而构成。相邻的链节(13)中的一个链节(13)的前端相对于另一个链节(13)的后端以能自由转动的方式连接。链条(11)通过在链条(11)的长度方向被拉伸，而向一个方向前进。链节板(12)具有向链条(11)的长度方向(X)延伸的第1端部(20)和第2端部(21)、以及被设置在第1端部(20)和第2端部(21)之间、且与长度方向(X)交叉的中间部(22)。中间部(22)的厚度大于第1端部(20)以及第2端部(21)的厚度。
摘要（英）：

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).
