Conventionally, in this kind of electromagnetic relay, as shown in FIG. 8, a permanent magnet 3 and two magnetic pole plates 2a,
2b is attached to the assembly 8.
It was placed from above and covered with cover 1. A holding portion 9 is provided on the front flange portion 16 of the coil assembly 7 for swingingly holding the contact spring driver 4;
The drive body 4 moves in a direction perpendicular to the axial direction of the iron core 5, thereby displacing the contact springs 12 disposed on both sides of the coil assembly 7 to turn on/off the contacts.

る。 Referring to FIG. 1, in one embodiment of the present invention, the coil assembly 7 has grooves 161 on both sides of the front flange portion 16. The insulator coil cover 17 has a protrusion 171 that fits into the groove 161 on the inner wall surface. These protrusions 171 are slid into the grooves 161 from above, and the insulator coil cover 17 is fixed to the coil assembly 7,
Insulation between the contact spring 12 and the coil 15 is ensured.
Referring to FIG. 2, the creepage distance between the coil 15 and the contact spring 12 is between the groove 161 and the protrusion 171.
It is clear that this is ensured by fitting with.
