<P>PROBLEM TO BE SOLVED: To provide a roller for a transport device capable of rotating at a high speed without applying abrasion or a line pressure on a transported article even if it is accumulated, nor generating a loss of synchronism phenomenon, and a transport device (roller conveyor, belt conveyor). Ž<P>SOLUTION: An outer roller is free-rotatably mounted outside a drive shaft, and a center roller is integrally rotatably arranged on an outer periphery of the drive shaft. Inner rollers are radially arranged between the central roller and the outer roller and integrally mounted to the outer roller. Rotation is transmitted from the center roller to the inner roller by rotation of the drive shaft, and the outer roller rotates around the drive shaft as a center. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
