きるという効果を奏するものである。As described above, the present invention provides a coil bobbin with a plurality of protrusions, holes that fit with the protrusions are drilled in the lower limit expansion button and the upper limit plate, respectively, and a large diameter portion that abuts the periphery of the opening surface of the hole. is formed in a substantially conical shape at the top of the protrusion, and when the protrusion is inserted and fitted into the hole, the outer diameter of the large diameter part bends, increasing the inner diameter of the hole by 1
1. Shape the groove of the upper surface opening with medium diameter into the large diameter part, and insert both corner plates into the magnetic pole teeth of the inner stator, respectively, and the coil is formed by fitting the protrusions and holes. 7 (-") Since it is fixed to the bottle, when inserting the protrusion with a large diameter part into the hole of the shaded plate, the large diameter part has a groove so that the inner lip 11
By bending, the outer diameter overlaps the inner diameter of the hole, allowing the large diameter part to fit smoothly into the hole. Because it is formed slightly smaller than the thickness of the shading plate, the lower surface of the large diameter part comes into contact with the opening edge of the hole in the shading plate, preventing the shading plate from vibrating up and down.In this way, the protrusion of the coil bobbin simply By simply inserting the coil bobbin into the hole of the shading plate, the coil bobbin and the shading plate are firmly fixed. Therefore, vertical and horizontal wobbling of the upper and lower shading plates is eliminated, and the magnetic equal force cut changes at the same time as the rotor rotates. This has the effect of reducing noise without causing distortion.
