Abstract

PURPOSE:To form the badk side extending part of canilever shape of left and right side walls of a case main body, without deformation at metallic molds separation, by applying a slight shape deformation to the metallic molds. CONSTITUTION:The rear ends of left and right sliding metallic molds 14 are set slightly shorter than the rear end of left and right side walls 3, the rear metallic mold 11c is extended forward by the extent equivalent to the part and the said metallic mold 11c forms the rear ends of inner side surfaces of each left and right side wall 3 over upper and lower full width locally. As a result, even when the sliding metallic mold 14 moved innerward, since the rear metallic mold 11c latches the rear end of the left and right walls 3, 3 from the inside, pivotally bearing shafts 4, 4 are respectively removed from molded recesses 15, 15 of the sliding metallic molds 14, 14, without deformation due to drawing to the inner side to the rear end extending parts 3a, 3a.
