PROBLEM TO BE SOLVED: To provide each driven roll for a continuous casting machine in which each bearing arranged on a roll is hard to brake, and which has a long service life. SOLUTION: A plurality of rolls including a roll 23 are arranged on an almost straight line. On the outer circumferential face of both the edge parts in the axial direction of each roll, a cylindrical roller bearing 54 is arranged one by one to each edge part. The cylindrical roller 53 of the cylindrical roller bearing 54 is made slidable to the axial direction to an inner ring 50 which does not have a collar. A thrust self-aligning roller bearing 66 receiving an axial load is arranged at the outer part in the axial direction of the roll 23 located in the outer edge in the axial direction. A coil spring 59 applying force to the thrust self-aligning roller bearing 66 to the axial direction is arranged at the outer part in the axial direction of the thrust self-aligning roller bearing 66.
