To substantially reduce the abrasion wear of a connection part between a drive shaft and a roller, thereby extending the service life of a device and eventually reducing the operation cost of the device.
A device (1) for deformation-processing work-pieces comprises: a rotatable drive shaft (2) about a rotation axis (a); a tool (3), specifically a roller, fixed to the drive shaft (2); and a shape connection part (4), specifically a toothed shaft coupling, between the drive shaft (2) and the tool (3). The torque of the drive shaft (2) can be transferred to the tool (3) by the shape connection part (4). In this configuration, the shape connection part (4) extends across a first axial direction section (5), a second axial direction section (6) is present outside the first axial direction section (5), and in the second axial direction section (6), the drive shaft (2) and the tool (3) are formed so as to transfer a radial force and have first columnar fitting surfaces (7 and 8) which cooperate with each other.
