PROBLEM TO BE SOLVED: To provide a pressing apparatus capable of controlling a position of a plate holding member by a simple mechanism.SOLUTION: A pressing apparatus 1 according to an embodiment of the present invention includes: a punch 5; a die 7; a plate holding member 9 supported by a compression pin 19 extending from the punch 5 toward the die 7; a cam slider 13 slidably mounted on the die 7; and a cam driver 11 for sliding the cam slider 13. After the plate holding member 9 and the die 7 clamp a workpiece 3, the die 7 relatively moves toward the punch 5, and the cam driver 11 abuts the cam slider 13, thus sliding the cam slider 13. Before starting the pressing and/or during the pressing, the sliding of the cam slider 13 causes the plate holding member 9 to be pressed toward the punch 5, separating the plate holding member from the workpiece 3.SELECTED DRAWING: Figure 1 【課題】簡易な機構で板押えの位置制御を行うプレス成形装置を提供する。【解決手段】本発明に係るプレス成形装置１は、パンチ５と、ダイ７と、パンチ５側からダイ７側に延出する加圧ピン１９に支持された板押え９と、ダイ７にスライド可能に取り付けられてカムスライダ１３と、カムスライダ１３をスライドさせるカムドライバ１１とを有し、板押え９とダイ７により被加工材３を挟持した後、ダイ７がパンチ５側に相対的に移動してカムドライバ１３がカムスライダ１１に当接することでカムスライダ１３がスライドし、プレス成形開始前及び／又はプレス成形中にカムスライダ１３のスライドによって板押え９がパンチ５側に押圧され、被加工材３から離れるようにしたことを特徴とするものである。【選択図】 図１
