Claims

[Scope of utility model registration request]

An iron core around which a coil is wound, a yoke which is arranged parallel to the iron core and whose rear end is bent at an almost right angle and which is fixed to the rear end surface of the iron core and forms part of a magnetic path together with the iron core. a rotary armature bent at an obtuse angle, an inner bending line supported by the front edge of the yoke, and an outer bending line being pressed toward the yoke by a pressing piece of a U-shaped support spring described later; and both sides of the yoke. an insulator frame fixed to the part and in which fixed terminals, neutral terminals, etc. are implanted;
a movable contact spring whose rear end is fixed to the neutral terminal and has a movable contact at its tip; and a U-shaped support spring disposed in front of the iron core and rotary armature, and which is attached to the insulator frame on both sides. A protruding piece that engages with the formed retaining part is formed protrudingly, and a pressing piece that is biased in a direction to press the outer bend line of the rotary armature toward the yoke is protruded obliquely from the front part. a U-shaped support spring formed therein, one end of the rotary armature is attracted to the iron core, the other end presses the movable contact spring, and the fixed terminal is fixed to the movable contact and the fixed terminal. An electromagnetic relay that opens and closes between contacts, wherein the U-shaped support spring has second protrusions protruding from both sides of the lower front surface thereof that abut against the front end surface of the insulator frame. . ,
