Claims

[Claims for Utility Model Registration] (1) In a connecting part of an offset conveyor chain where the link spacing is small, divided plastic bushings that can be separated in the axial direction of the connecting pin are integrally molded on opposing plastic links, respectively. . A plastic offset conveyor chain with rollers, in which both the divided bodies are inserted into the center hole of the roller from both sides and connected with the connecting portion of the offset conveyor chain with a large link interval by the connecting pin. (2) A plastic offset conveyor chain with rollers according to claim 1, in which one of the divided bodies concentrically fits into the center hole of the other divided body. (3) A plastic offset conveyor chain with rollers according to claim 1, in which both the divided bodies have the same diameter and their end faces are in contact with each other.
