An end roller of a curved conveyor has an pivot shaft and a plurality of short rollers rotatably mounted on the pivot shaft. A bearing with an outer race of a larger outer diameter than the outer diameter of the short roller is interposed between at least the adjacent short rollers located near an outer peripheral side of the belt. A bearing having an outer race of the same size outer diameter as the outer diameter of the short rollers may also applicable. Frictional noises from the end rollers during the rotation of the conveyor belt may be suppressed.
