PROBLEM TO BE SOLVED: To provide a press working device for forming a groove part on a plate member, in which a plate thickness of the groove part can be accurately and easily formed.SOLUTION: In a press working device for forming a groove part on a plate member, the press working device comprises: an upper die 4 on the surface of which a shape corresponding to the groove part is formed; a slide 5 descending when working the plate member; and an uneven load absorption mechanism 6 in which the upper die 4 is fitted to the slide 5. The uneven load absorption mechanism 6 comprises a first mechanism part 6a to which the upper die 4 is fixed and a second mechanism part 6b fixed to the slide 5. The first mechanism part 6a and the second mechanism part 6b are connected to each other by spring bodies 61. The first mechanism part 6a is provided with columnar guide shaft bodies 62 extending in a vertical direction. The second mechanism part 6b is provided with guide holes 63 to which the guide shaft bodies 62 are fitted so as to be linearly and vertically movable.SELECTED DRAWING: Figure 2 |
