Claims (1)

[Scope of utility model registration request] A main body is integrally formed with a connecting piece that protrudes from the main body and has protrusions on both sides and a neck portion having a diameter smaller than that between the protrusions at the base, and each of the protrusions is recessed into the main body. a link formed with a recessed part, a narrow part that is continuous with each of the recessed parts at a position opposite to the connecting piece and receives the neck part, and a retaining part that protrudes from each of the recessed parts in an eave shape and covers the recessed parts. Then, with the adjacent links bent together and the protrusions on both sides of the adjacent links facing the arrangement direction of the links, insert the connecting piece of the adjacent link between the retaining parts, and bend the adjacent link. is rotated around its longitudinal axis in the bent state, and after the protrusion of the adjacent link is inserted into the recess, the neck is brought closer to the straight state than the bent state, so that the neck part is brought into the narrow part. Chain, characterized by acceptance.
