PROBLEM TO BE SOLVED: To provide a forging method, which improves productivity by press-molding of two pieces of works to be forged at one time in one pressurizing step. SOLUTION: By lowering an upper outer ram 8 vertically downward, press-molding of a member 17 to be forged is carried out in the pressurizing straight axis direction with a lower-part lower-die 6 and a lower-part upper-die 15, and press-molding of a member 16 to be forged is simultaneously carried out with an upper-part lower-die 11 and an upper-part upper-die 14.
