摘要：
A transmission chain includes a plurality of unitary chain links, each of which has parallel first and second side plates, first and second connecting pins, first and second pivot pins, and first and second pivot seats. The first and second pivot pins of one of the chain links are connected pivotally, removably and respectively to the first and second pivot seats of an adjacent one of the chain links, so as to enable the transmission chain to possess the characteristics of an adjustable chain length.
