Abstract:
A magnetic bearing device includes a magnet generating a magnetic field at a protrusion formed toward a roll shaft, and a body portion supporting the magnet in one direction. The roll shaft is supported while an air gap is formed between the roll shaft and the protrusion, and both sides of the protrusion are rounded.
