PROBLEM TO BE SOLVED: To perform front and rear turning-over operation of a front and rear asymmetrical die in a short period of time. SOLUTION: A gooseneck die 18 of press brake 10 is attachable to an upper die supporting member 12, which is extended right and left in the direction of a first axis X and moves vertically, and comprises an attachment part 20, a connection part 22, and a die part 24. The attachment part 20 can be attached to the upper die supporting member 12. The connection part 22 is connected to the attachment part 20 so as to swing between a machining posture and a non-machining posture around the first axis X. The die part 24 is attached to the connection part 22 rotatably around a second axis Y crossing with the first axis X, and has a front and rear asymmetrical shape in which blade tips 24a extends obliquely.
