<P>PROBLEM TO BE SOLVED: To provide a coil winding nozzle which can achieve cost reduction by enhancing productivity of a small-sized coil and can achieve mass production of highly reliable small-sized coil. <P>SOLUTION: A substantially columnar nozzle having a winding hole 4 for feeding out a coil winding 9 is provided with a D-cut region 7 produced by D-cutting the side face of the nozzle by a predetermined length from the distal end 6 in the axial direction. The D-cut region 7 reaches the inner surface of the winding hole 4 and R is formed at the outlet 4b of the winding hole 4 at the distal end 6 toward the outer circumference of the nozzle. Consequently, productivity of small-sized coil is enhanced and a highly reliable small-sized coil can be manufactured. <P>COPYRIGHT: (C)2009,JPO&INPIT |
