Claims

[Scope of utility model registration request]

The armature is attracted against the elastic force of the braking spring by the excitation of the electromagnetic coil installed inside the yoke.
In this negative actuation type electromagnetic brake that releases the braking of the shaft by releasing the grip of the shaft side member between the armature and the side plate, a release plate formed of a plate material and having a U-shape in plan view is provided, and one end of the release plate is connected to the yoke. A brake release device for a negative actuation type electromagnetic brake, characterized in that the release plate is pivotably pivoted on the side, and the release plate is provided with a pressing part that pushes the armature and separates it from the shaft side member by rotation of the release plate. .
