A curved belt conveyor is provided to drive a curved belt at quick speed while stably supporting the curved belt and to prevent separation of the curved belt between inner and outer rails and deflection of the curved belt. A curved belt conveyor has a body frame formed in a fan rib shape. A curved belt is mounted to the body frame. Guide rollers are successively mounted to the outside of the curved belt. A taper roller is mounted to the driving part by a bearing, and a path recess groove is formed to the large diameter part. A taper roller is mounted to a slave part by a bearing, and a path recess groove is formed to the large diameter part. A guide roller moves along the body frame and moves an article in a curved direction by giving driving force to the curved belt. The curved belt conveyor comprises supports(7) each having an upper end projection(51), an intermediate protruded part(52), and a lower end projection(53); inner rails(5) fixed to the upper and lower end projections of the supports arranged to the body frame; outer rails(6) fixed to the outside of the intermediate protruded parts of the supports; and roller assemblies(9) mounted between the inner and outer rails and successively arranged along the outer periphery of the curved belt. In the roller assemblies, a pair of upper rollers(33) and lower rollers(34) are mounted to a single fastening bolt shaft(30). The upper and lower rollers are mounted toward the inside of the curved belt. A space part is formed between the upper roller and the lower roller. An annular rod(6a) of the outer rail is situated to the space pace.
