The electromagnetic relay according to the present embodiment is the same as the conventional example, except for the support 17 of the base 10 of the conventional electromagnetic relay. However, for convenience of description, FIGS. 1 and 2 show only the base 10 and the yoke 24. That is, a guide groove 17a similar to the conventional example is formed in the support 17 of the base 10, but a slit 17c communicating with the guide groove 17a is formed above the guide groove 17a. Of the cutout pieces 18 and 19 formed by providing the slit 17c, a pressing projection 18a is formed on the inner surface of the cutout piece 18 so as to press against the engaging projection 24b of the yoke 24 and press in the thickness direction. ing. On the other hand, cut piece 1
A locking claw 19a is provided on the inner surface of the locking member 9 to lock the engaging projection 24b and prevent the engaging protrusion 24b from coming off.

来例と同様であるので、説明を省略する。Therefore, the guide groove 1 of the support 17
When the guide projection 24a of the yoke 24 is inserted into the 7a and pressed down, the pressing projection 18a presses against the engagement projection 24b to urge the yoke 24 in the plate thickness direction. It is locked to the part 24b to prevent it from falling off. The other parts are the same as those of the above-described conventional example, and the description is omitted.

う利点がある。According to the present embodiment, the inserted yoke 24
When the pressing protrusion 18a is pressed against the engaging protrusion 24b, the cutout piece 18 provided with the pressing protrusion 18a elastically deforms outward. For this reason, the frictional resistance during insertion is reduced,
Assembly work becomes easier. Further, even after the insertion, the pressing projection 18a of the cutout piece 18 always presses the engaging projection 24b of the yoke 24 against the cutout piece 19 on the opposite side, so that there is an advantage that the electromagnet block 20 does not rattle. .

作業が完了し、生産性が向上するという効果がある。As is apparent from the above description, according to the electromagnetic relay of the first aspect of the present invention, the pressing projection provided on the support presses the engaging projection provided on the side end surface of the yoke. Then, the yoke is pressed in the thickness direction. For this reason, the electromagnet block composed of the yoke is positioned on the base without looseness. As a result, assembling accuracy is improved, and there is no variation in operating characteristics. In addition, when the engaging projection projecting from the side end surface of the yoke is pressed into the slit provided in the support of the base, at least one of the cutout pieces is elastically deformed outward. For this reason, the frictional resistance is reduced, and the assembling work is facilitated. As a result, there is no need to strictly control the dimensional accuracy of the guide grooves and slits, and the manufacture of parts becomes easier. Further, according to the second aspect, not only the rattling of the electromagnet block can be prevented, but also the locking claw provided on the support body prevents the yoke from coming off, so that the assembling operation can be completed with one touch, and the productivity is improved. There is.
