Abstract
Inner links of a chain are formed as an integral link unit, each having a pair of connecting pin portions and a pair of plate portions coupling the pair of connecting pin portions, so as to have higher strength and improved durability, whereby the cost of the chain is reduced because of the ease of assembly and a reduction in the number of components. The chain is formed by coupling together link units and pairs of link plates alternately and pivotally in a longitudinal direction of the chain. The link unit is formed by inseparably joining a pair of connecting pin portions and a pair of plate portions at joint parts.
