摘要： A roller hemming processing apparatus adapted to perform a hemming processing has a hemming die, on which a panel-like workpiece having a hemming flange portion on a periphery portion thereof, is positioned and supported, a roller hemming processing tool that is moved along a longitudinal direction of the hemming flange portion to bend the hemming flange portion at a root portion thereof while pressing the hemming flange portion toward the hemming die, and a nesting block disposed at a part of the periphery of the hemming die. The nesting block performs positioning of the workpiece by being brought into contact with the root portion of the hemming flange portion with which the workpiece is formed. The nesting block is elastically supported to be retractable in the pressing direction and to be swingably displaceable in the longitudinal direction of the hemming flange portion.
