A forming device wherein: a movable journal mold (10U, 10B) and a movable pin mold (12) are caused to move in an axial direction toward a fixed journal mold (9U, 9B) from a state in which the raw journal section (Ja) of a raw material (4) is held between the movable journal mold (10U, 10B) and the fixed journal mold (9U, 9B), and in which the movable pin mold (12) is applied to a raw pin part (Pa); and the movable pin mold (12) is caused to move in the axial direction and an orthogonal direction. A raw arm section (Aa) is thereby compressed from either side in the axial direction, the thickness thereof being reduced to the thickness of the arm section of the forged crankshaft. Pressure is applied to the raw pin part (Pa) in the axial direction and the orthogonal direction, the amount of eccentricity thereof being raised to the degree of eccentricity of the pin part of the forged crankshaft.
