A upper tool holder for a press brake includes a holder body; an upper tool clamper provided on the holder body and capable of swinging when replacing the upper tool; an auxiliary urging mechanism that functions as resistance when opening the upper tool clamper further in order to replace the upper tool, and functions so as to support a closing operation when closing the upper tool clamper from a further opened state; and a pusher provided in the auxiliary urging mechanism and urged in a closing direction of the upper tool clamper. According to the upper tool holder, unexpected drop-off of the upper tool can be prevented, so that safety can be improved.
