description PROBLEM TO BE SOLVED: To provide a press forming die device capable of executing a press formation by the so-called press-and-cut work in one process and by one die device and removing the spring-back without necessitating any perception or experience when a work of flat plate shape is pressed into an asymmetric box section. SOLUTION: This press forming die device consists of an upper press die 112 provided with a V-shaped projected part 114 which is projected downward and asymmetric corner parts 112a, 112b on each side and a lower die 1. The lower die 1 consists of a body 2 having a recessed part 3 to be opened upward, a movable die 50 which is arranged in the recessed part 3 movably in the vertical direction and having a V-shaped recessed part 20 corresponding to the V-shaped projected part 114 of the upper press die 112, and fixed dies 6, 7 which are fixed in the recessed part 3 and limit the corner part corresponding to an asymmetric corner part of the upper press die 112.
