PROBLEM TO BE SOLVED: To obtain a deep drawing press which makes a large working space available for discharging and carrying in a raw material and a product, makes a wrinkle pressing force adjustment possible at the material position and, is of a simple constitution. SOLUTION: In this press, four wrinkle press cylinders 21 are activated for pressing a raw material on a die 37 with different forces respectively via a wrinkle pressing board 29. Deep drawing is performed by activating a punch drive hydraulic cylinder 10 so as to lower a punch 16 for pushing the raw material into the die 37 hole. A slide block is made to be slid on a slide base by driving a slide block driving cylinder. An elevating cylinder 40 is activated at a position where two slide blocks are separated the most so as to lower die holders 34 along stays 2. Both slide blocks are inserted into the slide block insertion hole 35, which is a rectangular through hole formed on the die holder 34. A product M whose processing is completed can be taken out easily.
