巻線具１を用い、導出溝６を介して導出した線材
２の先端を引張りながら固定した状態で巻線具１
を回転させ、回転軸方向の往復の送りをかけなが
ら線材２を巻軸部５の外周に多層巻きするもので
ある。 That is, a winding tool 1 is used in which a winding shaft part 5 projects from the center of an end surface 4 of a cylindrical base 3, and a lead-out groove 6 is formed in the end surface 4 extending from the base of the winding shaft part 5 to the outer periphery. The winding tool 1 is fixed while pulling the tip of the wire rod 2 led out through the lead-out groove 6.
The wire rod 2 is wound in multiple layers around the outer periphery of the winding shaft portion 5 while being rotated and fed back and forth in the direction of the rotation axis.
なお、他の円柱状の巻線具（図示せず）の端面
に巻軸部５の先端面を当接させ、それらの巻線具
の対向する端面間にて巻軸部５に巻線することも
ある。 Note that the tip end surface of the winding shaft 5 is brought into contact with the end surface of another cylindrical winding tool (not shown), and the wire is wound around the winding shaft 5 between the opposing end surfaces of those winding tools. Sometimes.
しかし、このような巻線具によつて製造される
コイル７は、第１３図に示すように、線材２の巻

ネツトとコイル７との間隔を狭めることが困難と
なつてモータの小型化を阻害するし、ロータがコ
イル７に接触して断線が生じるおそれがあつて、
特に問題となる。 For example, when the coil 7 is used as a drive coil for a brushless motor, it becomes difficult to narrow the distance between the rotor-side magnet and the coil 7, which impedes miniaturization of the motor, and the rotor comes into contact with the coil 7. There is a risk of wire breakage.
This is particularly problematic.

達していればよい。 Moreover, the cross-sectional shape of the concave groove is arbitrary as long as the wire 34 enters and is held in the groove. The point is to form a step part whose depth changes in the middle of the groove into which the wire rod 34 is fitted, and before and after this step part there is a deep groove part having a depth equal to or greater than the wire diameter of the wire rod, and a shallow groove part smaller than the wire diameter. It is sufficient that the shallow groove reaches all the way to the side of the winding shaft.
そして、カツターを形成する場合にも、上述し
