ことを特徴とする負作動形電磁ブレーキ。 A field core disposed within an electromagnetic coil, an armature having a cylindrical portion inserted into an inner hole of the field core so as to be movable toward and away from the magnetic pole surface of the field core, and the cylindrical portion of the armature and the field core. The armature is inserted in a cylindrical space between the inner hole of the armature and the end face of each winding end is pressed against the plane of the field core side and the base of the cylindrical part, respectively, in a direction to separate the armature from the magnetic pole face of the field core. In a negative operation type electromagnetic brake equipped with a compression coil spring that biases, the inner diameter of the armature-side wound end of the compression coil spring is smaller than the inner diameter of a portion other than this wound end, and the cylindrical portion A negative actuation type electromagnetic brake characterized by having approximately the same diameter as the outside diameter of the base.
