An engagement chain (12) has two chain members (12a, 12b), which are capable of selectively advancing and retreating. Each of the chain members (12a, 12b) includes link plates (21, 22), each of which has two pin holes (23a, 23b), and coupling pins (24). The link plates (21, 22) are pivotally coupled together in series by the coupling pins (24) in the corresponding pin holes (23a, 23b). The two pin holes (23a, 23b) are aligned in the advancing/retreating direction (Z) and are sized differently from each other. Each of the coupling pins (24) of each chain member (12a, 12b) is tightly received in the smaller pin hole (23a) of the two pin holes (23a, 23b) of one of any adjacent two of the link plates (21, 22) in the advancing/retreating direction (Z) and is loosely received in the larger pin hole (23b) of the two pin holes (23a, 23b) of the other one of the two adjacent link plates. In a state in which the chain members (12a, 12b) are integrated with each other, any two of the coupling pins (24) that are opposed to each other are in the same received states in the corresponding pin holes (23a, 23b).
