Abstract
A method for producing a forged crankshaft includes: a clumping step of holding a first region by clumping a first region of a bar-like material by a pair of first dies, and a decentering step of decentering a second region of the bar-like material with second dies while the first region is held. The second region is a pin-corresponding part which is to be the pin. The first region is a crank arm-corresponding part which is to be the crank arm. The decentering direction by the second die is a direction perpendicular to each of the clumping direction of the first dies and the longitudinal direction of the bar-like material, and is the same direction as the decentering direction of the corresponding pin. This improves material yield while suppressing increase in the facility cost.
