い。 In Figure 3A, the magnetic cover is already
It is formed by extrusion processing or the like from an aluminum plate approximately 0.3 mm thick, and is inserted into the jig 6. 6
a is a center guide, and 6b is a protrusion for angle positioning. Next, this is press-fitted into the yoke 1 as shown in FIG. 3B. Next, as shown in FIG. 3C, the jig 7
and 8, in which the magnet 3 is inserted into the jig 8, the jig 7 is pulled up, the jig 8 is pushed in, and the magnet 3 is attached to the yoke 1 and the magnetic cover 5.
Press fit between. Here, the inner periphery of the magnet is covered with a cylindrical magnet cover. Next, Figure 3D
As shown in the figure, squeeze the four parts of the magnetic cover 5 where the magnet 3 is not inserted, and press the squeezed part 5b (second
(see Figure E) and position the magnet 3. Next, after preheating this, the adhesive 2 is dripped around the magnet 3 as shown in FIG. It penetrates into the gap between the inner peripheral surface and the outer peripheral surface of the magnetic cover 5, and fixes the yoke 1, the magnet 3, and the magnetic cover 5 to each other. Then, the excess adhesive flows down, but the large diameter part 5a of the magnetic cover 5
It is stopped by the yoke 1 and does not flow out from the yoke 1.

付工程を容易確実化する。 According to the present invention, the magnet can be firmly fixed. In addition, conventionally, it was necessary to strictly control assembly such as the amount of adhesive and bonding time, but the magnetic cover according to the present invention has a structure that allows the magnetic cover to be attached between the large diameter part that fits into the inner periphery of the yoke and the inner periphery of the yoke. Since it has a small diameter part into which the magnet is press-fitted, the adhesive will not flow out and it can provide an excellent field function. Furthermore, magnets,
Not only can adhesives be selected from a wide range, but the management of the magnet fixation status is also greatly reduced.
Although the above embodiment has been explained using an aluminum magnetic cover, it goes without saying that the magnetic cover can be made of any material, whether magnetic or non-magnetic. be. Further, if the bottom part 5c is formed on the magnetic cover, it can be used as a part to abut against the jig 6 when the magnetic cover 5 and the magnet 3 are press-fitted during assembly, making the assembly process easier and more reliable.
