Abstract
A press apparatusincludes: a first die parthaving a first working surface; a second die parthaving a second working surface; a first support memberthat supports the first die part; and a second support memberthat supports the second die part. At least one of the first and second die partsandprovides a clearance S, Spresent in at least a portion of an overlap region R, the overlap region being overlapped by the first and second working surfacesandas viewed in the press direction, the dimension of the clearance in the press direction in a no-load condition being non-uniform along two orthogonal directions as viewed in the press direction. The minimum dimension of the clearance Si within an inner region Rin the no-load condition is smaller than the minimum dimension of the clearance Swithin an outer region Rin the no-load condition, the inner region defined by, and located inward of, the middle line between the centroid G and edge of the overlap region R
