Abstract

An electromagnetic relay includes a mobile component movable at time of energization and de-energization of a coil, and a fixed component immovable at the time of energization and de-energization of the coil. A damping space is provided between the mobile component and the fixed component and changes in volume with the movement of the mobile component. A gap provided between the mobile component and the fixed component serves as a passage that allows gas to flow into or out of the damping space when the damping space changes in volume. A size of the gap is set such that a pressure is generated in the damping space to cause a damping force acting on the mobile component when the damping space changes in volume.
