PROBLEM TO BE SOLVED: To provide a stator manufacturing device which can twist mold many number of nearly U shape wire materials in a uniform shape at one time. SOLUTION: This device has an inside jig 3, in which an inside holding part 35 is annularly arranged for holding one part of linear portions 11 of a nearly U shaped wire material 10, and an outside jig 4, in which an outside holding part 45 is annularly arranged in concentric with the inside holding part 35 for holding the other part of two linear portions 11. In a twist molding device 100 in which a connecting portion 12 of the nearly U shape line material 10 is twist molded by rotating the inside jig 3 and the outside jig 4 relatively, an energization mechanism 5 is additionally provided for energizing a tip of the linear portion 11 and the connecting portion 12 in a compression direction. |
