Abstract: A conveyor chain constructed so as to prevent a leakage of lubricant oil to the outside. The conveyor chain comprises a plurality of bearing elements operable to revolve in a raceway between an outer circumferential surface of a bush and an inner circumferential surface of a roller. A pair of right and left thrust bearing annular members are press-fitted onto the outer circumferential surface of the bush and are positioned between the inner side surface of an inner link plate and the outwardly-facing end surfaces of the bearing elements. Annular sealing members for sealing lubricant oil within bearing element raceway are disposed between the inner circumferential surface of the roller and an inner circumferential surface of the thrust bearing annular member. The sealing members slidably contact but are not deformed by the inner circumferential surface of the roller.
