PROBLEM TO BE SOLVED: To provide a press die capable of executing bending and composite bending having mutual interference part in one body. SOLUTION: This press die has freely turnable rotary cams 33 arranged on the lower die side on which the sheet is placed; the rotary cams comprise a stationary rotary cam 41 restricted in axial movement and a movable rotary cam 42 placed coaxially on one end or both ends of the stationary rotary cam 41 and capable of axial movement, and further the contact surfaces 51 and 52 of the edge parts for the contact of the stationary rotary cam 41 and the movable rotary cam 42 are formed slant by a prescribed angleθdeg. to the turning axis.
