PROBLEM TO BE SOLVED: To provide a roller type forging machine which applies nearly constant pressure to metal blank passing through between a pair of rotating forging rollers, and thereby can almost uniformize diameter-reduction amount of the worked metal blank. SOLUTION: The roller type forging machine is provided, which applies pressure by a pair of the rotating forging rollers 31 and 32 to the metal blank 2 passing through between the rotating forging rollers 31 and 32 and conveyed along a prescribed conveying root 22 to perform plastic working of the metal blank into a planned shape, wherein the forging rollers 31 and 32 are constituted in such a way that the pushing force to the metal blank 7 passing through the rollers 31 and 32 is adjustable to a prescribed value, and that a pair of the forging rollers 31 and 32 are composed of the fixed roller 31 arranged at a prescribed position and fixed and the movable roller 32 which is juxtaposed to the fixed roller 31 and is arranged so that it can swing by approaching and separating from the fixed roller 31 with the control of a energizing means according to the size of the passing through metal blank 7.
