A mold holder device in a press brake includes a mold clamp that clamps a mold with respect to a mold contacting surface provided for a holder body of the mold holder device. The mold clamp is pivotally arranged on the holder body. A long groove is formed in a mold clamping surface with which the mold clamp clamps the mold with respect to the mold contacting surface. The long groove is in parallel with a pivot axis of the mold clamp. A metal pipe member has a longitudinal slit and is inserted in a rotation restricted state into the long groove. A part of an outer peripheral surface of the pipe member is protruded toward the mold contacting surface.
