This electromagnetic clutch includes an electromagnetic coil 7 wound in a ring shape, a circular core 20 having a ring groove-shaped coil accommodating portion 8 for accommodating the electromagnetic coil 7, an outer peripheral surface of the core 20 and an opening of the coil accommodating portion 8. The rotor 11 has a shape that substantially covers the surface but is arranged so as not to contact the core 20, and a rotatable armature 13 arranged close to the friction surface 12 of the rotor 11. ing. In this electromagnetic clutch, when a current is applied to the electromagnetic coil 7 while the rotor 11 is rotating, the rotor 11 is excited, and the armature 13 adjacent thereto is attracted and brought into contact with the friction surface 12 of the rotor 11, so that the armature 13 together with the rotor 11 Rotate. When the power supply to the electromagnetic coil 7 is stopped, the excitation of the rotor 11 is released, and the armature 13 that has been attracted to the rotor 11 until then is separated from the rotor 11 by the retraction member 18, and the rotation of the armature 13 stops. That is, the rotation of the rotor 11 is intermittently transmitted to the armature 13 by turning ON / OFF the power supply to the electromagnetic coil 7.

On the other hand, the armature 13 is connected to the rotary shaft 17 of the compressor 16, and the rotary shaft 17 of the compressor 16 is driven when the amateur 13 is rotated. Amateur 13 in this case
Is a double plate of an inner armature 13a and an outer armature 13b arranged concentrically on the outer side of the inner armature 13a. When the rotor 11 sucks the inner armature 13a, the inner armature 13a is first sucked, and then the outer armature 13a is sucked. Amateur 1

The power supply to the electromagnetic coil 7 is turned on / off by a controller (not shown) of the air conditioner.
When the air conditioner is switched on while the engine is started and the rotor 11 is rotating, the current flows from the controller to the electromagnetic coil 7 and the rotating shaft 17 of the compressor 16 is driven. It Further, even when the air conditioner is operating, if the controller controls ON / OFF of the power supply to the electromagnetic coil 7 according to the temperature inside the vehicle, the rotating shaft 17 of the compressor 16 intermittently rotates and stops accordingly, and the air blown out into the vehicle. Is maintained at a predetermined temperature.

Has been conventionally manufactured by the manufacturing process as shown in FIGS. 1. As shown in FIG. 11 (a), a thick ring-shaped steel plate 2
Prepare 1. The steel plate 21 is subjected to a bond process (bonderite process), so that workability in press working is enhanced. 2. The steel plate 21 is pressed by cold forging as shown in FIG.
1 (b), (c) ring-shaped coil housing portion 8
Then, a circular core 20 is formed in which a housing space 9 that can house other members (the inner wall 11a of the rotor 11 and the bearing 19 in FIG. 3) is formed. 3. Annealing the core 20 (annealing),
The residual strain left on the core 20 after pressing is reduced. 4. As shown in FIG. 11 (d), the open end surface 22 of the core 20 is cut and smoothed so that the core 11 comes into contact with the rotor 11 even if the distance between the open end surface 22 and the rotor 11 (FIG. 9) facing the core 20 is narrow. Try not to. Thus, the core 20 is completed. 5. Normally, the core 20 is adapted to be distributed in the state of the core assembly of FIG. 10 to which a mounting bracket (usually called a flange) 10 for mounting the core 20 on the compressor 16 is mounted. Therefore, in this case, a separately press-molded flange 10 is attached to the back side of the core 20 by welding as shown in FIGS. The flange 10 is provided with a screw hole 10a for screwing to the compressor 16 and a protrusion 10b for positioning at the time of mounting. 6. Normally, in the core assembly, as shown in FIG. 11G, the electromagnetic coil 7 is set in the coil housing portion 8 of the core 20.

になるという問題があった。In the method of manufacturing the core shown in FIG. 11, the circular steel plate 21 must be pressed once by cold forging to form the coil accommodating portion 8 having a substantially U-shaped cross section. In order to make the core 20, a deep-drawing press was required. However, for this purpose, a bonding process is required to perform deep narrowing, and large strain is accumulated and remains in the core 20 after performing the narrowing. Therefore, an annealing process (annealing process) for eliminating or reducing the distortion is performed. ) Was needed. For this reason, there is a problem that it takes a long time to manufacture the core 20 and the cost of the core 20 increases.
