Claims

[Scope of utility model registration request]

An excitation coil wound around a cylindrical coil frame, a 7-shaped yoke with a short piece inserted into the coil frame and a long piece arranged along the outer periphery of the excitation coil, and a short piece of the yoke with a long piece arranged along the outer periphery of the excitation coil. A magnetic circuit is constructed with a 7-shaped armature which is rotatably joined to the tip and whose long piece is inserted into the coil frame, and when the excitation coil is energized, the long piece of the armature connects to the short piece of the yoke. In an electromagnetic relay in which the center part of a contact spring having a movable contact at the tip is attached to the long piece of the armature, a guide groove is provided in the inner wall of the coil frame along the insertion direction of the contact spring. An electromagnetic relay characterized by being provided with.
