Disclosed is a roller hemming device, which is capable of excellent hemming even when a subject to be hemmed is located in a relatively narrow place, and reducing maintenance frequency. Specifically disclosed is a roller hemming device, which includes a preliminary bending roller for performing preliminary bending of a work, a final bending roller for performing final bending of the work, and an arm for setting attitudes of the preliminary bending roller and the final bending roller at desired positions and angles. The preliminary bending roller has an axis inclined with respect to a horizontal direction and is arranged at such a position not to come in contact with the work during the final bending. The final bending roller is formed in a circular truncated cone, has an axis which is inclined with respect to the horizontal direction so that, during the final bending, a large diameter surface thereof faces toward the work and a processing surface thereof is horizontally positioned, and is arranged at such a position not to come in contact with the work during the preliminary bending. The preliminary bending roller and the final bending roller are arranged along a top-bottom direction, each having a processing point located in a vicinity of an axis of the arm.
