To provide a press forming machine of a curved plate, by which necessary working ratio is attained even in the end parts of a die, which are apart from the main jack and hardly obtain the necessary load.

An upper die 5 and a lower die 6 are formed so as to coincide with the size of a workpiece, the upper die 5 has the upper die body 50 which is connected with the main jack 7, a center die 51 which is fixed to the upper die body 50 and arranged in the vicinity of the main jack 7 and outer peripheral dies 52 which are arranged by being further away from the main jack 7 than the center die 51 and the outer peripheral dies 52 are arranged movably in the direction so as to approach the upper die body 50 through a sub-jack 8 or be away from the upper die body 50.
