Abstract
A metal sheet is formed with a target shape portion, a remaining portion surrounding the target shape portion and elongated portion(s) joining the target shape portion with the remaining portion. An apparatus cuts out the target shape portion from the metal sheet by shearing the joint portion at a region bordering on the target portion. The apparatus includes a blade member movable to a position below the joint portion and a fixed blade member for pressing the joint portion from above. The apparatus, being placed at a fixed position, rotates or linearly moves the movable blade member with respect to the fixed blade member to shear the joint portion at the region and bend a sheared-side end of the joint portion upward.
