Abstract
A press brake includes paired fixation links, upper link arm, lower link arm and paired raised-lowered links, which form a parallel link mechanism configured to allow an operation panel to be raised and lowered. The press brake includes a spring configured to generate torque depending on a height position of the operation panel in an opposite direction to torque generated by weight of the operation panel; and a torque hinge configured to maintain a posture of the parallel link mechanism by absorbing a torque difference between the torque generated by the weight of the operation panel and the torque generated by the spring.
