PROBLEM TO BE SOLVED: To provide a reversing device for a long workpiece capable of reversing a shaped steel by any angle with a simple mechanism, not inducing an increase in the cost of a facility, and maintainable easily. SOLUTION: Inverting rollers are so disposed at an interval that allow the long workpiece to be installed therebetween. A reversing cam groove extending in the circumferential direction is formed in the outer peripheral surface of each of the reversing rollers. The portion of the first rotating position of the reversing cam groove is so formed that can receive the long workpiece to be reversed in the initial attitude. The portion of the second rotating position thereof is so formed that can hold the long workpiece in the reversed state reversed by a predetermined angle from the initial attitude. The portion of the reversing cam groove between the first rotating position and the second rotating position is formed to be so changed that the long workpiece can be gradually rotated from the initial attitude toward the reversed attitude. The reversing rollers are synchronously rotated in the same directions or mutually reverse directions by a drive mechanism so that the portion of the first rotating position of the reversing cam groove and the portion of the second rotating portion thereof are brought into contact with the long workpiece at the same timing.
