Abstract
A roller hemming device includes a large diameter roller having a large tapered surface and a small diameter roller having a small cylindrical surface. The small diameter roller is coaxially disposed with the large diameter roller. The small diameter roller and the large diameter roller enable to relatively move in an axial direction. The outer diameter of the small cylindrical surface is smaller than the minimum outer diameter of the large tapered surface.
