After being fitted in the recess of the upper surface of the base 4, it is bent into a gap 4a formed between the base 4 and the spool 3 into a substantially V shape, and the movable iron piece 5 is attached to the tip of the horizontal portion 6a. When the vertical portion 6b of the hinge spring 6 whose one end side is fixed by crimping is inserted, the elastic tongue piece 6c formed by cutting and raising the vertical portion 6b of the hinge spring 6 presses and contacts the periphery of the magnetic pole portion 1b of the iron core 1. The locking claw 6d cut and raised in one direction engages with the stepped portion 3a provided on the end surface of the spool 3 to prevent the movable iron piece 5 from rotating around the magnetic pole portion 1b of the iron core 1 as a fulcrum. Hinged on. The card 7 engaged with the tip of the movable iron piece 5 is reciprocally movable in the vertical direction, and the lower end of the card 7 is engaged with the tip of the movable contact piece 8 having the movable contact 8a. Further, the movable contact 8a of the movable contact piece 8 faces the fixed contact 9a of the fixed contact piece 9 located on the lower side of the movable contact 8a so that the movable contact 8a can come into contact with and separate from the fixed contact 9a.

Is separated from the magnetic pole portion 1a. When a voltage is applied to the coil 2 to excite it,
The magnetic pole portion 1a of the iron core 1 attracts the movable iron piece 5,
Rotates against the spring force of the movable contact piece 8 and pushes the card 7 downward, so that the movable contact piece 8 rotates and the movable contact 8a comes into contact with the fixed contact 9a. 5 is attracted to the magnetic pole portion 1 a of the iron core 1. Then, when the excitation of the coil 2 is released, the card 7 is pushed upward by the spring force of the movable contact piece 8, the movable iron piece 5 is separated from the magnetic pole portion 1a of the iron core 1, and the movable contact 8a is opened from the fixed contact 9a. Release it to return to the original state.

とになり、抜け止めが確実になるという効果がある。As is apparent from the above description, according to claims 1 to 4 of the electromagnetic relay according to the present invention, the vertical portion of the hinge spring having one end of the movable iron piece fixed to the horizontal portion is the collar portion of the spool. Since it is directly assembled to the end face, unlike the conventional example, the error of the component dimension and the assembly error are not accumulated, and the positioning accuracy of the movable iron piece is high. Therefore, not only the magnetic efficiency is improved, but also the amount of displacement of the free end portion of the movable iron piece does not vary, and the electromagnetic relay in which the operating characteristics and the contact pressure do not vary is obtained. According to claim 2, since the hinge spring is biased in the plate thickness direction by the elastic tongue,
No rattling in the plate thickness direction. According to the third aspect, the lower end portion of the hinge spring is positionally regulated in the plate thickness direction by the step portion provided on the end face of the collar portion of the spool, so that rattling in the plate thickness direction does not occur. According to claim 4, since the lower end of the hinge spring abuts on the locking projection, the upper end of the locking claw locks on the lower end surface of the protrusion formed on the flange end surface of the spool. Eliminates rattling in the vertical direction. Particularly, by letting the lower end portion of the hinge spring ride on the step portion according to the third aspect, the locking claw can be more reliably locked to the lower end surface of the protrusion provided on the flange end surface of the spool. This has the effect of making sure that it will not come off.
