In a coil forming device, an edge line in an escape region is formed so that a clearance between the edge line in the escape region and a recess portion in an axis direction is larger than a minimum clearance between the edge line in an inclined region and the recess portion in the axis direction. When a second die is rotated relative to a first die in the clockwise direction the flat-square conductive material end is bent in flatwise bending by the recess portion and the inclined region of a protrusion portion, and then, the flat-square conductive material end reaches the escape region.

Coil forming device

A conductor shaping apparatus includes a first shaping die, a second shaping die and a holding section configured to hold the conductor and rotates the second shaping die about a rotational axis with respect to the first shaping die, and it further includes a first movement restricting portion formed in the first shaping die and configured to contact with a portion of the conductor so as to restrict a movement of the conductor together with the second shaping die when the second shaping die is rotated in a direction approaching the first shaping die, and a second movement restricting portion that is formed in the first shaping die and is configured to contact with a portion of the conductor so as to restrict the movement of the conductor together with the second shaping die when the second shaping die is rotated in a direction apart from the first shaping die.
