A conveyor chain having a large diameter load-carrying roller and a small diameter running roller coaxially mounted on a connecting pin which alternately connects an inner link plate with an outer link plate, a cover mounted on said link plate of a configuration to cover a gap between adjacent load-carrying rollers and a gap between adjacent running rollers preventing entrance of foreign matter. Included are chain covers covering sideways the inner and outer link plates and travelling rollers of the conveyor chain, and gap covers for preventing entrance of foreign substances which covers the gap between adjacent loading rollers and also covers the gap between adjacent travelling rollers. The gap covers have a projection portion in a position between adjacent loading rollers having a surface which is lower than an outside diameter of the loading rollers and higher than lower surfaces of the chain covers.
A chain conveyor system comprising a conveyor chain and including loading rollers of a large diameter and travelling rollers of a small diameter coaxially mounted on connecting pins for connecting inner and outer link plates in an alternate manner and chain covers covering sideways said inner and outer link plates and travelling rollers of said conveyor chain, characterized in that:
