PURPOSE: A bending apparatus for a deformed bar is provided to easily bend a deformed car into a desired shape without correction by bending the deformed car with a main bending unit and then regulating the curvature of the deformed bar with an auxiliary bending unit. CONSTITUTION: A bending apparatus(100) for a deformed bar(10) comprises a main bending unit(110) and an auxiliary bending unit(120). The main bending unit comprises a drive bending roller and a driven bending roller to bend the deformed bar. The auxiliary bending unit comprises a plurality of guide rollers to regulate the curvature of the deformed bar bent by the main bending unit.
