ABSTRACT:
An electromagnetic relay structure having a plate spring and a yoke secured to a base by forming a vibration damping portion integral with a terminal and by securing the terminal to the base by insertion molding. The vibration damping portion is disposed between an L-shaped yoke, an end of which is secured to the base, and the terminal, which is also fixed to the base. The vibration damping portion is spot welded to a plate spring, which is secured to the yoke. A spot welding machine is provided for fixing the plate spring to the vibration damping portion. The spot welding machine has electrodes that are rotated by motors while effecting spot welding of the material.
