Claims

[Scope of utility model registration request]

An armature supported movably only in the axial direction, a disk disposed opposite the armature, a pressing member that presses the armature toward the disk, and a magnetic force that pushes the armature against the pressing force of the pressing member. A field core having a built-in electromagnetic coil for attraction and to which a support member for supporting the armature is fixed, and an elastic member protrudes from one of opposing surfaces of the armature and the field core. In the negative actuating electromagnetic brake installed in
The negative actuation type electromagnetic brake, wherein the elastic member is installed with a gap formed between the elastic member and the opening of a recess or a through hole formed to open on the opposing surface side.
