も、共に計らんとすることを目的とする。However, in the case of adopting the above configuration, the ears e formed on both sides of the movable iron piece M are pivotally attached to the hinge fixed above the yoke Y. Therefore, in order to prevent contact due to residual magnetism when the magnetic pole P is not energized, the gap g (normally 0.3 to 0.5 [m
m]), the formation of the gap g leads to a decrease in magnetic efficiency, and the sprinkling S ′ arranged on the side of the yoke Y is not limited to the case where the installation space is limited. Has a small amount of extra space, and it is difficult to install it and it is necessary to consider the temperature rise. Further, it is a practical problem that the bending angle (the arrow portion in the figure) with respect to the movable iron piece M is accurately formed at a predetermined angle. However, it is not bulky, does not lead to a reduction in product cost, and cannot improve productivity efficiency. The present invention is intended to eliminate the above-mentioned difficulties as much as possible. The yoke Y and the movable iron piece M are brought into direct contact with each other to enhance the magnetic efficiency, and the structure is simplified to generate a slight noise during operation. The purpose is to reduce the temperature rise and decrease, and improve the productivity.

る。In the electromagnetic relay thus constructed, the upper surface of the elastic piece S is fixed to the movable iron piece M, and the lower engaging portion k 3 of the elastic piece is fixed to the yoke Y. Since the back surface of the joint portion k 2 is restrained, the open state of the magnetic pole P is elastically maintained as shown in FIG. 2 when the coil C is not biased.
According to the present invention, as described above, the elastic piece S acting as a spring is obtained by simply punching out a thin plate, and the engaging portions k 3 and k 4 thereof are elastic to the fixed plate K. Since the movable iron piece M is directly fitted to the notch c 2 and directly touches the yoke Y, it can be assembled quickly because it is only pressed against the yoke Y. Since it does not require a large gear gap g like the one like, it not only has good magnetic permeability and reduces microvibration during operation, but also has less man-hours and can improve productivity. It is possible to expect excellent effects that can be sufficiently achieved.
