Drivig chain, especially for bicycle

摘要

The cycle transmission chain is formed from alternate external (2) and internal (3) links connected by their spindles (4). The internal and external links are formed from external (21) and internal (31) plates. Each plate has two bulged ends, each with a hole for receiving the hollow spindle, and joined by connecting holes (26,36). The holes are elongated and their ends are rounded. The ends of the hollow spindles have clamping notches.
