An edge bending device for a workpiece having an outer circumferential edge bending part where the edge of one plate material is temporarily bent to be bent so as to wrap around the edge of the workpiece, the edge bending device having a communication hole communicating between the inside and the outside; a lower mold body having a support protrusion on which a workpiece can be positioned and placed with the plate material facing downward; an upper mold body that can be moved up and down above the lower mold body; and an upper mold body that can be moved vertically relative to each other within a regulated range. a positioning pad that is supported by the upper mold body and biased downward by a spring and can come into contact with the workpiece on the support protrusion; and a positioning pad that is fixed to the upper mold body and abuts the outer peripheral edge bending part from above. A possible upper die; a receiving die that is movable vertically within a regulated range, is supported by the upper mold body, is biased downward by a spring, and can abut the inner circumferential bent portion from above; a yoke that is arranged to penetrate through the communication hole of the support protrusion and is swingable by a horizontal support shaft and supported by the lower mold body; and a yoke that is fixed to the inner end of the yoke and abuts the inner circumferential edge bending part from below. a bending die that can be contacted; a pressure receiving part provided at the outer end of the yoke; and a direction in which the bending die is provided in the upper die body and comes into contact with the pressure receiving part as the upper die body descends, and the bending die comes into contact with the inner peripheral edge bending part. An edge bending device comprising: a pressing portion for rotationally biasing a yoke;
