Abstract
A compressive torsion forming device for processing a processing material using a first die and a second die facing each other includes a sliding portion that includes a first hydraulic chamber, and slides in accordance with a change in internal pressure of the first hydraulic chamber so as to move the first die in a direction of an axis; a rotating table provided with the second die and rotatable about the axis; a table support portion provided opposite to the second die with the rotating table interposed therebetween in the direction of the axis; and a rotational bearing that rotatably supports the rotating table with respect to the table support portion, and receives a force acting on the rotating table in a direction from the second die toward the rotating table.
