Abstract: An electromagnetic relay device includes a mover, a plunger, and a solenoid unit that causes the plunger to reciprocate. The mover includes a movable contact movable to abut onto or separate from a stationary contact. The plunger causes the mover to reciprocate to accordingly cause the movable contact to abut onto or separate from the stationary contact. A heat-resistant member is interposed between the insulator and the mover. The plunger enables indirect abutment onto the mover through the insulator and the heat-resistant member. A heat-resistant temperature of the heat-resistant member is set to be higher than that of the insulator.

Abstract: A press-fit fixing portion fixes a drive unit and a relay unit by press-fitting a claw portion and the recess portion. A sealing member is provided on an outside of the relay unit and the drive unit. An inner cover forms a sealed space for sealing an arc-extinguishing gas together with the sealing member. An electromagnetic relay is configured to make it possible both an adjustment of a press-fitting amount of the claw portion and the recess portion and an adjustment of the gap between a ceramic insulator at an end of a shaft and a movable element by making each of the relay unit and the drive unit in a manufacturing process to the same state as in when a magnetizing coil is energized.
