保持せしめて成るリレー。1 A substantially U-shaped yoke 1 with one end of the iron core 3 inserted into the relay coil 4, a contact spring 6 having a contact 15 at its tip to open and close the contact, and one end 2a side of the yoke 1 The other end 2b is attracted to the magnetic pole surface of the iron core 3.
A substantially L-shaped armature 2 that drives the contact spring 6 on the side, and a tip 1 at the other end of the yoke 1.
3 rotatably clamps the armature 2 to urge the armature 2 in the return direction, and a presser spring 7 is integrally formed from the base end 6a side of the contact spring 6. The tip side of the presser spring plate 7a extending from the base end 6a side to the one end 2a side of the armature 2 is used as the support end X of the presser spring 7, and the base end 6a side of the contact spring 6 is used as the free end 31. The presser spring 7 is cut and raised from the presser spring plate 7a, and a bent portion 32 for bending the free end 31 of the presser spring 7 in a direction away from the yoke 1 is formed in the middle part of the presser spring 7. A concave surface 11 with a flat outer surface extending to both ends of the armature 2 is formed at the center of the outer surface of the bent portion of the armature 2 formed in an L-shape, and the tip 13 of the yoke 1 is connected to the folded portion of the armature 2. At the same time, the portion of the presser spring 7 closer to the support end X than the bent portion 32 of the presser spring 7 is brought into contact with the outer surface of the concave surface 11 of the armature 2, thereby applying the biasing force of the presser spring 7. A relay consisting of an armature 2 held by the armature.
