Abstract: A coil wire material is bent by a first roll, a second roll, and a third roll. The bent coil wire material is pressed in a screwing direction, to shape a coil spring having a desired diameter and a pitch. A desired pitch can he accurately formed in a manner that a second roll provided on a downstream side of a conveying direction of the coil wire material is configured to be able to move hack and forth along the screwing direction of the coil spring and to be tiltable about an axis of rotation parallel to the conveying direction of the coil wire material.
