  • Engagement chain and movable body movement device
    Patent number: 10295018
    Abstract: An engagement chain has two chain members. Each of the chain members includes link plates, each of which has two pin holes, and coupling pins. The two pin holes are aligned in the advancing/retreating direction and are sized differently from each other. Each of the coupling pins of each chain member is tightly received in the smaller pin hole of the two pin holes of one of any adjacent two of the link plates in the advancing/retreating direction and is loosely received in the larger pin hole of the two pin holes of the other one of the two adjacent link plates. In a state in which the chain members are integrated with each other, any two of the coupling pins that are opposed to each other are in the same received states in the corresponding pin holes.
