換し、カード６０によって１よねである可動接点板６１
を駆動するので、長いカードストロークと大きな吸引力
を得ることができるという利点がある。This electromagnet device is a flapper type electromagnet, which works between one piece 57 of the five armatures and the magnetic pole part 53 of the magnetic body 55 (the attractive force is converted into leverage by the other piece 58 of the armature 59, and the card 60 is used to The movable contact plate 61 is
, so it has the advantage of being able to obtain long card strokes and large suction power.

引力特性が変化するため、電磁継電器の特性値のばらつ
きが大きくなるという欠点があった。However, in this electromagnet device, the bending accuracy of the angle θ when bending the armature 59 into an abbreviated shape is poor, and as a result, the position of the card 60 with respect to the magnetic pole face 66 is ΔX.
In particular, since the stroke of the card 60 relative to the stroke of the magnetic pole face 66 has become larger due to the increased leverage of the armature 59, the variation including the stroke position of the card 60 becomes large. card 6
If the zero stroke varies, as shown in FIG. 6, the attractive force characteristics change, resulting in a disadvantage that the characteristic values of the electromagnetic relay vary greatly.

カードとを備えたものである。The electromagnet device of the present invention has a coil, a penetration part that penetrates the coil in the axial direction, and a yoke part located on the outside of the coil, and the penetration part and the yoke part are connected at one end side. A magnetic body that is U-shaped and has the other end of the through part as a magnetic pole part and the other end of the yoke part as a fulcrum part, and a bent part is rotatably magnetically coupled to the fulcrum part.

定した吸引力を得ることができる。According to the configuration of the present invention, the armature is biased so that its magnetic pole face separates from the magnetic pole part of the magnetic material.
When the coil is energized, magnetic flux flows through the magnetic material penetration portion, yoke portion, and armature, and an attractive force is generated between the magnetic pole portion and the magnetic pole surface of the armature, causing the armature to rotate. On the other hand, since the cards were simultaneously molded using the armature's magnetic pole surface as the mold reference surface, even if the bending angle of the armature varies during manufacturing, the position where the card's spring system etc. is driven relative to the armature's magnetic pole surface, that is, the card position, will vary. Since it does not stick, variations in stroke can be reduced and stable suction force can be obtained.
