Abstract

In an electromagnetic relay device, a mover includes a movable contact movable to abut onto and separate from a stationary contact through a contact region defined between the movable and the stationary contacts. A plunger causes the mover to reciprocate to accordingly cause the movable contact to abut onto or separate from the stationary contact. A solenoid unit of the electromagnetic relay device includes an electromagnetic coil, a movable core, and a support member that slidably supports an outer peripheral surface of a slidable contact portion of the movable core. A movable wall member is located between the slidable contact portion and the contact region. The movable wall member reciprocates together with the plunger. The movable wall member is arranged to occupy a region in the electromagnetic relay device. The region contains at least the slidable contact portion when viewed in the reciprocation direction.
