PROBLEM TO BE SOLVED: To provide a metal chain which maintains chain strength while reducing the weight and size of the chain and reduces a workload and costs for assembly of the chain.SOLUTION: Multiple inner links 110 and outer links 120 are alternately connected with each other in a chain longitudinal direction in a bendable manner to form a metal chain 100. Each outer link 120 includes: a pair of front and rear pin parts 121; and a pair of left and right outer plate parts 122. Each inner link 110 includes: a pair of front and rear bush parts 111 which rotatably support the pin parts 121; and a pair of left and right inner plate parts 112. Each inner link 110 is formed by two components, i.e., a first inner link component 110A and a second inner link component 110B which are integrally formed and respectively have inner plate parts 112A, 112B. |
