摘要： In a forming apparatus, movable journal dies (10U, 10B) and stationary journal dies (9U, 9B) retain rough journal portions (Ja) of a preform blank (4) therebetween, and reference crank pin die (11) and movable crank pin dies (12) contact rough crank pin portions (Pa) thereof, and in this state, the movable journal dies (10U, 10B) and the movable crank pin dies (12) are moved axially toward the reference crank pin die (11) and the reference crank pin die (11) and the movable crank pin dies (12) are moved in a direction perpendicular to an axial direction. With this, weighted rough arm portions (Aa) are axially compressed to reduce their thickness to that of weighted arms of a forged crankshaft, and the rough crank pin portions (Pa) are pressed in the direction perpendicular to the axial direction to increase an amount of eccentricity to that of the crank pins of the forged crankshaft.
