Abstract:

The purpose of the present invention is to provide an electromagnetic relay having excellent workability in assembling work, and an electromagnetic device. An electromagnetic relay (1) is provided with a contact point section (2), an electromagnet (5), an armature unit (6), and a base (4B). The contact point section (2) has a fixed contact point (21), and a movable spring (25) having a movable contact point (26). In accordance with excitation of the electromagnet (5), the armature unit (6) moves such that the movable contact point (26) is displaced between a closed position at which the movable contact point is in contact with the fixed contact point (21), and an open position at which the movable contact point is separated from the fixed contact point (21). The base (4B) holds, on one surface (40) side, the contact point section (2) and the electromagnet (5). In an alignment direction in which the base (4B) and the electromagnet (5) are aligned with each other, the movable contact point (26) is disposed between the base (4B) and the fixed contact point (21). The armature unit (6) has a pressing section (80) that displaces the movable contact point (26) by pressing one surface (250) of the movable spring (25), said one surface being on the side facing the fixed contact point (21).
