ータリ式ネジ転造機。 An arc-shaped stationary die is arranged opposite to a circular rotary die attached to the rotating main shaft with a predetermined rolling space in between, and a material supply means is provided for supplying bolt material to the rolling space. The rotary type thread rolling machine is provided with a reaction force supporting means for supporting the rolling reaction force acting on the main shaft during rolling of the bolt material, and the reaction force supporting means is provided with the above-mentioned rolling reaction force at a position opposite to the fixed die. A plurality of main bearing rollers that come into contact with the circumferential surface of the main shaft, a roller support member that supports these rollers and is slidable in the direction in which the rolling reaction force is applied, and a roller support member that supports these rollers and is configured to provide a predetermined rolling reaction force. A rotary thread rolling machine comprising the roller support member and hydraulic urging means for urging the main shaft toward the fixed die via the main bearing roller.
