<P>PROBLEM TO BE SOLVED: To provide a press forming device in which the height of an opening between a main movable blade and a bearing blade is enlarged without enlarging the stroke width of a movable die and without lengthening a cycle time. Ž<P>SOLUTION: This press forming apparatus 1 includes the bearing blade 21, the main movable blade 31, a cam driver 32 and a passive cam 33. The cam driver 32 has a driver sliding part 321 for moving a first cam sliding part 331 which is formed on the passive cam 33 and the passive cam 33 approximately in the horizontal direction when the driver is lowered. The passive cam 33 has a second cam sliding part 332 for raising the bearing blade 21 by sliding on a bearing sliding part 212 formed on the bearing blade 21 when moving back and forth and is provided with a biasing means 330 for biasing the passive cam 33 in the opposite direction to the moving direction accompanying the lowering of the cam driver 32.
