<p>The present invention provides a conveyor chain (100) capable of independently and easily mounting ball units (130) into a single chain link (110) to prevent the separation thereof, and also facilitating the dismounting thereof. This conveyor chain comprises a number of chain links (110) mutually connected in the chain longitudinal direction, each chain link having a plurality of hinge parts (112) protruding alternately from a front edge and a rear edge as an integrally molded unit; and a ball unit (130) holding a ball (131) which is free to be rotated while being exposed to both sides of the chain link, the ball unit being detachably installed in a direction normal to the longitudinal and transverse directions of the chain into a unit installation area defined between adjacent hinge parts and a hinge pin longitudinally from the chain direction. The ball unit is positioned and fixed transversely in the chain double-side direction and longitudinally in the chain direction by engagement with the chain link.</p> |
